wrf/v4.0.2
a9017c2d · ·WRF Version 4.0.2 WRF Model Version 4.0.2: UPDATES The WRF model has been updated to Version 4.0.2 on November 9, 2018. The WRF Preprocessing System (WPS) has also been updated to Version 4.0.2. Acknowledgements: We would like to thank Tanya Smirnova (NOAA), Alexander Davies (US Naval Academy), Jeremy Silver (U. Melbourne), @sodoesburningbus, and Alexander Ukhov (KAUST) for their contributions to this release. This is a bug fix release. Following are fixes associated with this release. Dynamics: * Fix zero-valued d02 dry potential temperature perturbation from horizontal interpolation.This fix does not change the WRF model simulation results. However, if users grab the initial condition dry potential temperature perturbation field, "T" in the netcdf file, that value will be identically zero (the field is initialized within the solver routine for all subsequent time steps). Most WRF post-processors will assume that the field is a horizontally and vertically uniform dry potential temperature = 300 K, which would provide almost reasonable-looking values for temperature near the surface. After the first time step, the model results will be correct. This bug is in v4.0 and v4.0.1. Physics: Microphysics: * Morrison 2-moment scheme with consideration of CESM-NCSU RCP4.5 climatological aerosol A loop counter and an array index are changed from real to integer. This change makes the code able to compile on Cray. Explicitly name a small value as a PARAMETER so that the small value can be represented with single precision on Cray Cumulus parameterization: * A minor modification was made to the Grell 3 scheme to prevent random seed array bounds errors in the cup_forcing_ens_3d subroutine * Correct a few syntaxes in multi-scale Kain-Fritsch to make the code able to compile on Cray Land surface scheme: * Bug fix in RUC LSM for the computation of LAI for particular day when LAI parameter is read in from the VEGPARM.TBL. The bug makes the value of LAI smaller than it should be. * Bug fix for Noah LSM when rdalai2d is set to true. In areas where LAI is zero (and vegetation fraction isn’t), unrealistic sensible and latent heat fluxes are produced due to this bug, leading to model crash. PBL scheme: * The MYJ and QNSE PBLs use surface water vapor mixing ratio as low boundary condition for moisture and compute it from the latent heat flux, while other PBL schemes use directly latent heat flux as low boundary condition. Therefore, there is a special computation of latent heat flux inside RUC LSM to get correct surface Qv. In original code the check in the surface driver is made on the option of surface layer scheme, land not PBL scheme. Therefore, if MYJ PBL is not used together with MYJ surface layer scheme, there will be inaccuracy in low boundary condition for moisture. * A check was implemented to stop the real or wrf program if bl_mynn_edmf (which is set to 1 by default in the MYNN scheme) is being used in combination with either the ishallow or shcu_physics option turned on. A message informs the user that bl_mynn_edmf cannot be used with the other 2 options and the namelist must be modified. Ideal case: * The default value for vegfra in idealized cases was modified from a fraction to a percentage, consistent with the Noah LSM driver Data Assimilation: * Bug fix for WRFDA RANDOMCV when put_rand_seed=.false. and the compiler has a minimum size of random seed array larger than 10. * Fix WRFDA compilation when RTTOV-11 is built with HDF5-enabled. Chemistry: * Correct the chemical reaction rate constant for reaction: SO2 + OH -> SO4. This change applies only to the following chem_opt options: MOZART_KPP,MOZCART_KPP, T1_MOZCART_KPP,MOZART_MOSAIC_4BIN_KPP,MOZART_MOSAIC_4BIN_AQ_KPP. * Bug fix in optical_prep_gocart to better represent dust particles that have radii less than 0.46 microns. With this fix, the underestimation of AOD is overcome. * Bug fix for the contribution calculation of dust and sea salt bins into the MOZAIC bins. This fix leads to increased contribution of small dust and sea salt particles to AOD.

wrf/v4.0.1
f729619f · ·WRF Model Version 4.0.1: UPDATES The WRF model has been updated to Version 4.0.1 on October 2, 2018. The WRF Preprocessing System (WPS) has also been updated to Version 4.0.1. Acknowledgements: We would like to thank Mike Barlage, Jim Bresch, Greg Thompson, and May Wong for their contributions to this release. This is a bug fix release. Following are fixes associated with this release. Dynamics: * Hybrid vertical coordinate - In the original implementation of the hybrid vertical coordinate (v3.9), the cpp directives utilized capitalization to differentiate between the use of full-level (c1f, for example) and half-level (c1h, for example) 1d coefficient arrays. For several locations in module_small_step_em.F, the use of the "mu" array with the "t_2" field incorrectly was assigned to full levels. These errors are minor. * Moist potential temperature - In the porting of the theta_m mods from being ONLY inside of the WRF model to being part of the initialization step in the real and ideal programs, the start_em file was modified. Part of the computation of the pressure involves dry_theta * ( 1 + Rv/Rd Qv ). When the incoming data from the real or ideal program has the namelist option use_theta_m==1, then the factor ( 1 + Rv/Rd Qv ) was already included in the theta field. This error is dramatic for the initial conditions (more than 30 hPa in some locations), but the error dies out over time. Physics: * Microphysics, Thompson: * Bug has been in the code for approximately 10 years, skipping a reduced number of rain. * Increased maximum ice concentration permitting 10000/Liter whereas previously 500/Liter upper limit. * A series of new checks using "EQV" construct to provide some loops to be skipped. * Minor changes to lower limits of precip to eliminate really tiny values (~1E-9). * Removed extraneous ELSE blocks in reading lookup tables. * Eliminate air density - fix for extreme model top heights by Tanya Smirnovich for FIM model (and MPAS). * Set a higher value for min dust concentration when nucleating ice. * Land Surface Model, NoahMP: * Noah-MP frozen soil initialization- An incorrect sign change was introduced in v4.0, impacting soil moisture and soil temperature initialization. * Array out of bounds Noah-MP - Fix possible/likely array out of bounds by assuming homogeneous soil with depth.Only applies to opt_run=2. * Noah-MP snow liquid water movement - prevent excessive gravitational water movement. Fixes unrealistic snow density values during melt season. * Noah-MP divide by zero - Bug fix in v4.0 introduced a possible divide by zero when LAI is zero. * Noah-MP leaf aerodynamic resistance - limit leaf aerodynamic resistance to prevent very large canopy exchange coefficients with high wind speed. Fire: * Wrong namelist entries given in test/em_real/namelist.input.fire Data Assimilation: * Cheyenne path change for crtm_coeffs_2.2.3 corrected for new file system directory structure. An array out-of-bounds error is fixed when cloud_cv_options is set (0, 1, or 2) and mp_physics is set (any value besides 0 or 98) such that any of xa%qrn, xa%qcw, xa%qci, xa%qsn, or xa%qgr are disabled and such that moist scalars qc, qr, qi, qs, and qg are enabled. See registry.var for more info. Error mode without fix: WRFDA will have a fatal error during the analysis update when bounds checking is turned on (debug mode). It is also possible that those moist scalars and correlated variables will be incorrectly updated when bounds-checking is turned off. * Bug fix for max_ext_its>=2 and cloud/w BE scaling factors (i.e. var_scaling6..11 and len_scaling6..11) that vary with outerloops. * Bug fix for ob.radar that contains rv=-999.99, rv_err=-888888.0, rf_err=-888888.0 to avoid excess check_max_iv prints. Chemistry: * convert_emiss compilation - Minor bug fix for convert_emiss compilation issue. The build target for convert_emiss was accidentally removed when error detection (not recognizing an argument for the ./compile script) was introduced with v4.0. Users will not be able to build the WRF Chem executable convert_emiss without this fix. * The WRF and WPS source codes are available from GitHub. Source code via tar files: 1.
