SNICAR snow albedo scheme updates A few substantial changes in the SNICAR module for the following updated snow albedo calculation features: - Updated ice optical properties from Flanner et al. (2021), with multiple types for ice refractive indices. - Updated aerosol optical properties from Flanner et al. (2021) with multiple dust types & new BC and OC optics. - Updated downward solar spectra from Flanner et al. (2021) for multiple condition types. - More accurate radiative transfer solver (adding-doubling) from Dang et al. (2019). - Nonspherical snow grain scheme from He et al. (2017). - BC-snow internal mixing scheme from He et al. (2017). - Dust-snow internal mixing scheme from He et al. (2019). - Hyperspectral (480-band, 10-nm spectral res) capability with all the above features. - New namelist controls for aerosol in snow and additional snow albedo diagnostic output variables. Specific notes - Code contributors: Cenlin He (NCAR/RAL) with advice from Dave Lawrence (NCAR/CGD) and Mark Flanner (UMich). - The manuscript to report this update is Cenlin He, Mark Flanner, David M Lawrence, Yu Gu: New features and enhancements in Community Land Model (CLM5) snow albedo modeling: description, sensitivity, and evaluation. Authorea. June 08, 2023. DOI:10.22541/essoar.168626390.01530324/v1 - These updates will change the snow and surface albedo results along with other surface fluxes changes. - There are a few new namelist options related to SNICAR scheme added to the namelist control. New namelist variables: snicar_numrad_snw = 5 or 480 wavelength bands, default 5 snicar_solarspec, default "mid_latitude_winter" among six available options snicar_dust_optics, default "sahara" among three avail. options snicar_snw_shape, default "hexagonal_plate" among fourn avail. options snicar_use_aerosol, default .true. snicar_snobc_intmix and snicar_snodst_intmix, default .false. means do not activate bc-snow and dust-snow internal mixing do_sno_oc, default .false., already appeared in previous code but in caps use_snicar_frc, default .false., existed before fsnowoptics now points to an updated 5-band file and gives the option for a 480-band file
