New features in ELM and MOSART

  1. Implementation of topography-based subgrid structure (topounits) and downscaling methods of atmospheric forcing from atmosphere grid to land topounits. (https://github.com/E3SM-Project/E3SM/pull/4273)

  2. Implementation of a sub-grid topographic parameterization in ELM that quantifies the effects of sub-grid topography on solar radiation flux. (https://github.com/E3SM-Project/E3SM/pull/4590 )

  3. Implementation of two-way land-river hydrological coupling through the infiltration of water on
    the floodplain during the flooding period. (https://github.com/E3SM-Project/E3SM/pull/5017 )

  4. Implementation of two-way river-ocean hydrological coupling between MOSART and MPAS-O. ( )

  5. Updates SNICAR-AD snow radiative transfer model to include non-spherical snow grain shape, internal mixing of dust-snow and solar-zenith-angle dependence of surface spectral irradiance under different atmospheric profiles. ( )

  6. Implementation of the impacts of irrigation, conservation agriculture, crop residue, glacier, and lithology on soil erosion and sediment yield in ELM-Erosion ( )
