Surface Energy budget/Fluxes
Incoming fluxes are in blue, outgoing are in green, turbulent exchanges with
the atmosphere are in purple. Sub-surface heat fluxes are in red.

Hydrology
Water sources due to the various components of the precipitation
are in blue, evapotranspiration sources/sinks are in green, and
canopy drip, snowmelt runoff, surface runoff, drainage and soil
water fluxes are in red.

Prognostic variables are in
blue.
