Why HRLDAS need to combine snow and rain as Precipitation? Why this need hourly interpolation of solar radiation?

Dear coworkers, my questions are about HRLDAS. I am runing HRLDAS with GLDAS-based forcing data. For running offline LSM such HRLDAS, we know we need atmospheric forcing and initial data. In...
