Included are: 1) 1h QPF exceeding 1h FFG for all forecast hours: :FFLDRO:surface:0-1 hour acc fcst: 2) 3h QPF exceeding 3h FFG for the 3h forecast: :FFLDRO:surface:0-3 hour acc fcst: 3) 6h QPF exceeding 6h FFG for the 6h forecast: :FFLDRO:surface:0-6 hour acc fcst: 4) 12h QPF exceeding 12h FFG for the 12h forecast: :FFLDRO:surface:0-12 hour acc fcst: ========================================================================= 2019-12-03: Eric James (17 UTC) HRRR-primary: Updated wrf.exe and real.exe to the top of the trunk. Two changes: 1) Maximum smoke concentration implemented (should only affect very small regions around the most intense fires; Ravan Ahmadov). 2) Bug fix for RRTMG shortwave, which should lead to a very small reduction in low-level daytime cold bias (Joe Olson) wrf.exe_21nov19_41992d4d and real.exe_21nov19_41992d4d ========================================================================= 2019-11-13: Tanya Smirnova (16 UTC) HRRR-primary: 1. Introduced a separated freezing point temperature for salty lakes: the Great Salt Lake, UT and Mono Lake, CA. The ice that has been built on these lakes already, was removed. wrf.exe.13nov19_f7485f48 and real.exe.13nov19_f7485f48 ========================================================================= 2019-09-24: David Dowell (21 UTC) HRRRDAS: "Rolling" ensemble design turned on. 18 of the ensemble members (odd-numbered members) are initialized at 0900 UTC, and the other 18 (even-numbered members) are initialized at 2100 UTC. Each member is cycled for 24 hours before being replaced. (Previously, all 36 members were initialized at 0900 UTC.) ========================================================================= 2019-09-24: David Dowell (09 UTC) HRRRDAS: Source of IC perturbations changed from GDASv14 to GDASv15. ========================================================================= 2019-09-20: Tanya Smirnova (19 UTC) HRRR-primary: Updated wrf.exe. The new executable uses Xu-Randall formulation to compute cloud fraction only when CLDFRA_BL is < 0.001. This is a better solution for cycled models. ========================================================================= 2019-09-20: David Dowell (18 UTC) HRRR-primary: CLDFRA_BL, QC_BL and QKE are added to HRRRX initialization from HRRRDAS. ========================================================================= 2019-09-18: Tanya Smirnova (23 UTC) HRRR-primary: Updated wrf.exe. The new executable includes bug fixes for the HRRR initialization in the pre-forecast. ========================================================================= 2019-09-17: Tanya Smirnova and Ming Hu (23 UTC) HRRR-primary: Updated surface cycling. The new executable adds QVG, QCG, QFX, HFX, UST and PBLH to cycled variables. This will help with cold-start initialization in the HRRR pre-forecast. ========================================================================= 2019-09-06: David Dowell (17 UTC) HRRRDAS: Turned off hourly, non-variational cloud building in ensemble members. Although it was producing a desirable increase in low-level water vapor, it was also causing spurious convection at short lead times. ========================================================================= 2019-08-27: Ming Hu (21 UTC) HRRR-primary: change GSI executable from: gsi.x_ProdGSI_soiltune_20190809_8e95ae2ff_Intel18_impi2018 to : gsi.x_ProdGSI_gsddev_20190827_2a6fb97_Intel18_impi2018 This is to use the original soil moisture/temperature adjustment before we increased the adjustment range to moisture and temperature. New executable works since cycle: 2019082721 ========================================================================= 2019-08-23: David Dowell (09 UTC) HRRRDAS: Atmospheric initial conditions (ensemble mean) now come from RAPX at 0900 UTC. Previously, HRRRDAS was initialized from GFS at 0300 UTC. ========================================================================= 2019-08-20: David Dowell (21 UTC) HRRRDAS: Turned on hourly, non-variational cloud building in ensemble members. The method is like that in HRRRX. ========================================================================= 2019-08-21: Eric James (17 UTC) HRRR-primary: Script change to eliminate the use of "ncks" tool that is apparently too inefficient to be used on WCOSS. Emissions info is now always copied in using Sam Trahan's "fires_ncfmake" tool (for both pre-forecast and full forecast), and smoke is cycled at the beginning of the 1h pre-forecast using Sam Trahan's "cycle_netcdf" tool. ========================================================================= 2019-08-14: David Dowell (23 UTC) HRRR-primary: Script change that affects initialization of QNIFA and QNWFA. These fields had been copied from HRRRDAS, when available, but now QNIFA and QNWFA will always be initialized from the RAP-primary through WPS. ========================================================================= 2019-08-14: David Dowell (04 UTC) HRRRDAS: Discontinued EnKF assimilation of METAR-based qv pseudo obs, which had been used for cloud building. ========================================================================= 2019-08-09: Tanya Smirnova (21 UTC) HRRR-primary: Update in soil temperature adjustment in GSI. This version will allow soil warming up to 1.5 K instead of 1.0 K in the previous version. ========================================================================= 2019-07-31: Tanya Smirnova (20 UTC) HRRR-primary: Bug fix for lake ice, that prevented ice from melting. ========================================================================= 2019-07-30: Tanya Smirnova (16 UTC) HRRR-primary: Tuned down albedo dependence on Solar Zenith Angle (SZA) for short vegetation. The parameter d=0.4 is changed to d=0.25. This modification will slightly reduce modrning/evening albedo to more reasonable values. ========================================================================= 2019-07-26: Ming Hu (23 UTC) HRRR-primary: Pulled back some changes for more aggressive soil moistening in GSI. The previous version was turning dry bias into moist causing too cold daytime temperatures. ========================================================================= 2019-07-19: Eric James (21 UTC) HRRR-primary: Emergency bug fix to FVCOM update to correct the check for missing value flag in FVCOM output. Missing values were being copied in for SST and TSK over Lake Superior. This is corrected starting with 21 UTC run. ========================================================================= 2019-07-16: David Dowell (21 UTC) HRRRDAS: Bug fix. HRRRX was previously receiving the mean of 36 member 1-h forecasts for initial conditions. Now HRRRX is correctly receiving the mean of the 36 member analyses. ========================================================================= 2019-07-09: Ming Hu (23 UTC) HRRR-primary: Modification to soil moisture update in GSI to more aggressive moistening to compensate for growing dry bias in 2-m dewpoint ========================================================================= 2019-06-19: Eric James (17 UTC) HRRR-primary: wrf.exe and real.exe and updated to revision cd7a535a. This update installs smoke-related code changes to fix a few minor bugs and make the code consistent with the recent changes made in the 6th order diffusion and interpolation of the RAP fields to the HRRR vertical grid (linear vs. lagrangian). The unused code was deleted in the plumerise module. Minor impact on meteorology via the smoke impact on radiation. ========================================================================= 2019-06-05: David Dowell (04 UTC) HRRRDAS: Bug fix. The change in GSI executable on May 10 led to erroneous radar-reflectivity DA in HRRRDAS. Today's change allows the reflectivity DA to work properly. ========================================================================= 2019-06-01: David Dowell HRRRDAS: LSM perturbations turned back on. Magnitudes are 25% of what had been used before May 23. ========================================================================= 2019-05-23: David Dowell HRRRDAS: LSM perturbations turned off after discovery that magnitudes were too large. ========================================================================= 2019-05-23: David Dowell HRRRDAS: Assimilation of METAR-based qv pseudo obs, for cloud building, turned on. ========================================================================= 2019-05-23: Eric James (22 UTC) HRRR-primary: Direct feedback effect for smoke turned on, with namelist change from: simple_dir_fdb = 0, to: simple_dir_fdb = 1, starting with free forecast at 22 UTC. ========================================================================= 2019-05-21: Jaymes Kenyon (20 UTC) HRRR-primary: wrf.exe and real.exe are updated to revision be9517d0. This update installs: 1) updates to the MYNN, intended to increase diffusion in the convective PBL 2) updates to the radiation driver, which remove the Xu–Randall cloud-fraction contribution 3) bug fixes for initialize_real (from G. Thompson), which correct the initialization of hydrometeor number concentrations and fix vertical-interpolation issues 4) bug fixes for the HAILCAST diagnostic (for HRRR applications) ========================================================================= 2019-05-21: Eric James (18 UTC) HRRR-primary: Bug fix for 1h pre-forecast radar processing: since the SLURM transition, only the first of the four sub-hourly radar tten arrays was being correctly calculated; the other arrays were set to zero (convective suppression). This is corrected with 18Z run. ========================================================================= 2019-05-21: Tanya Smirnova (16 UTC) HRRR-primary: SOILPARM.TBL is updated. This table produces good results with the new soil classification. ========================================================================= 2019-05-14: Jaymes Kenyon (19 UTC) HRRR-primary: wrf.exe is updated to revision 88fd813d. This update installs numerous bug fixes, modifications to the lake model initialization, and compiling optimizations. No change to real.exe. ========================================================================= 2019-05-10: Eric James (17 UTC) HRRR-primary: Bug fix in UPP to correct upward shortwave radiation at the surface. Field was always zero due to use of the wrong name for albedo variable used in the calculation. ========================================================================= 2019-05-10: David Dowell (04 UTC) HRRRDAS: gsi.x updated to latest version. (See June 5 log entry regarding the error in reflectivity DA that was introduced by this change.) ========================================================================= 2019-05-07: Jaymes Kenyon (13 UTC) HRRR-primary: wrf.exe and real.exe are updated to revision 4d7ff6c. This update installs Thompson MP from RAPv4/HRRRv3 into HRRRX. Static lookup tables for the revised MP sheme are also installed. ========================================================================= 2019-04-26: Jaymes Kenyon (15 UTC) HRRR-primary: wrf.exe and real.exe are updated to revision a5d47e49. Accompanying this update, the following WRF namelist settings are made: added: diff_6th_factor2 = 0.04 changed: moist_mix6_off = .false. (was .true.) scalar_mix6_off = .false. (was .true.) ========================================================================= 2019-04-25: Ming Hu HRRR-primary: da_update_bc.exe is updated to da_update_bc.exe_20190425_056e213_intel18 This update is to fix a bug in update_bc that accidentally change snow fields in wrfinput_d01. Please see GSD_UTL revision 056e21375d4bdc6b4548e180c8431a00cc347722 for more details. This version works since cycle 2019042518. ========================================================================= 2019-04-19: Eric James (19 UTC) HRRR-primary: Bug fix for FVCOM update. All land surface variables are now forced to be consistent with the new fractional sea ice field brought in from FVCOM. This is revision 664ca5ae ========================================================================= 2019-04-19: Jaymes Kenyon (17 UTC) HRRR-primary: wrf.exe and real.exe are updated to revsion a202b11d. No science-related mods are introduced, but significant improvements in memory usage and disk footprint are expected. ========================================================================= 2019-04-18: Jaymes Kenyon (19 UTC) HRRR-primary: updates to WRF namelist settings: (1) Wicker's adaptive implicit vertical-advection scheme is active via "zadvect_implicit = 1" (2) w-damping is removed via "w_damping = 0" (change to free forecast only) (3) the microphysics temperature-tendency limit ("mp_tend_lim") is removed (change to free forecast only) ========================================================================= 2019-04-15: Eric James (21 UTC) HRRR-primary: Backing out the previous change; got a crash in the LSM ========================================================================= 2019-04-15: Eric James (20 UTC) HRRR-primary: Bug fix for FVCOM update. ISLTYP, VGTYP, and LANDMASK were not getting updated to be consistent with fractional ice cover. Pending more discussion with Tanya, for now these variables will be set to ice value for gridpoints with FVCOM ice coverage greater than 10%, and water value elsewhere. ========================================================================= 2019-04-12: Eric James (20 UTC) HRRR-primary: Bug fix in FVCOM update: Implemented a check to make sure we don't copy in missing values (-99C) from FVCOM for SST/TSK. Sometimes not all of the Great Lakes have data in GLERL's FVCOM, and we want to only use the data if it's not missing! ========================================================================= 2019-04-12: Eric James (17 UTC) HRRR-primary: Enabled 15-min precip output in sub-hourly GRIB2 files. Currently includes total precip, snow (liquid equivalent), and graupel. ========================================================================= 2019-04-12: Trevor Alcott / Joe Olson (15 UTC) HRRR-primary: Turned on non-local transport of momentum in mass-flux scheme bl_mynn_edmf_mom = 1 ========================================================================= 2019-04-05: Eric James (21 UTC) HRRR-primary: Updated WRF executable to revision 460ae41b, which includes TKE cycling when cycling = true, as well as new subhourly precipitation bucket capability. Also this is the first compilation on the new OS, resulting in minor speedup. ========================================================================= 2019-03-12: Eric James (18 UTC) HRRR-primary: UPP is updated to output smoke on the lowest model level as 8m above ground level smoke, in 2D GRIB2 files. ========================================================================= 2019-03-11: Ming Hu HRRR-primary: process_NESDIS_imssnow.exe is updated to process_NESDIS_imssnow.exe_20190311_95b5446 This update is to fix a bug in snow/ice trim/building.

Fix for lake ice/snow - 971158fb. 2. Updated surface MYNN from Joe Olson - d5b15332. 3. Smoke change from Ravan - 8968e34c. It adds smoke extinction to the surface visibility diagnostics. ========================================================================= 2019-02-27: Ming Hu HRRR-primary: Since cycle 2019022722, GSI-hyb analysis uses pre-porcessed ensemble perturbations instead of reading GDAS ensembles directly. ========================================================================= 2019-02-26: Eric James (19 UTC) HRRR-primary: Turned on copying in of fractional sea ice from NOAA GLERL's FVCOM model with every run. FVCOM runs twice a day, and has output at 3h intervals, so we are grabbing the most recent run's forecast valid at the time closest to the HRRRX init time. This is expected to have a minor impact, most noticeable on fluxes and low-level temperatures over the Great Lakes. ========================================================================= 2019-02-21: Ming Hu HRRR-primary: process_NESDIS_imssnow.exe is updated to process_NESDIS_imssnow.exe_20190221_e19cbf3 This update is to fix a bug in snow/ice trim/building.
