Understanding soil processes beyond the traditional Darcy scale is essential to advancing hydrological and biogeochemical process-representation at the landscape scale. Soil's critical zone plays an outsized impact on water-carbon-energy exchanges between land and atmosphere. Although, observational constraints severely restrict measurements of several components of the critical zone, remote sensing observations from satellites or uncrewed aerial vehicles provide valuable proxies for understanding large-scale soil processes. We invite studies on process understanding of the critical zone beyond the Darcy scale using remote sensing for (but not limited to):-Scaling of critical zone processes -Land-atmospheric interactions/feedback -Soil moisture dynamics and controls -Soil hydraulic parameterization -Soil carbon and nutrient cycle -Surface-rootzone connectivity -Soil salinity and microbiological activityWe invite applications of soil moisture observing satellites (SMAP, SMOS, SENTINEL-1, NISAR, etc.), multi/hyperspectral remote sensing (MODIS, LANDSAT, SENTINEL-2, EMIT, PRISMA, EnMAP, PACE, etc.), large-scale reanalysis products, CYGNSS, etc., for studying critical zone soil processes.
