MPAS Version 8.2.0 This release of MPAS introduces several significant changes to MPAS-Atmosphere. New physics * The Noah-MP v5.0.1 land-surface model is now available by setting config_lsm_scheme = 'sf_noahmp' in the &physics namelist group. - New static files that include the 'soilcomp', 'soilcl1', 'soilcl2', 'soilcl3', and 'soilcl4' fields are required when activating Noah-MP in the model. * The aerosol-aware Thompson microphysics (as in WRF v4.1.4) is available by setting config_microp_scheme = 'mp_thompson_aerosols' in the &physics namelist group. - An aerosol climatology file (QNWFA_QNIFA_SIGMA_MONTHLY.dat) is used when running the init_atmosphere_model program to produce initial and lateral boundary conditions for nifa and nwfa. Physics changes * Physics schemes in the physics_mmm directory are now obtained from a separate, shared MMM-physics repository at compile time using the manage_externals tool. * The revised Monin-Obukhov scheme replaces the Monin-Obukhov scheme in the 'mesoscale_reference' suite. GPU capabilities * The scalar transport code has been ported to GPUs using OpenACC directives. - The atmosphere core must be compiled with OPENACC=true. - Additional timers in the log file capture host-device data transfer times. Infrastructure * The build system no longer requires an intermediate clean step when compiling one core before another.
