A daily time step version for the soil climate, biogeochemical, and trace gas
components of NASA-CASA has been developed and is currently being validated at
a number of research sites around the world. In order to better represent
localized climate and mineral processes on soil water and nutrient dynamics,
several important modifications are made, including development of moisture and
heat fluxes through layers in the plant-soil environment, and refinement of
microbial responses to wetting-drying episodes. A methane flux component is
being tested for northern wetlands sites.
