Research Data Sets: Land Atmosphere Interactions
In this section of the proposal, we elaborate our work that addresses the interactions among climate, physiography, and biotic interactions. The processes with which we are primarily concerned in this section are H2O, energy, and gaseous fluxes that represent important atmosphere-biosphere interactions. In some cases (C and N fluxes), the key processes overlap with work described under the biogeochemistry section of the proposal, but the focus here is on land-atmosphere interactions. Three major hypotheses guide the work in this section (L1–L3). The first of these is important for guiding a number of monitoring experiments focused on precipitation and soil H2O.
