Record Label : surface_net_upward_longwave_flux
Record Title : Surface Net Upward Longwave Flux
CF Standard Name : surface_net_upward_longwave_flux
Record Description : The surface called "surface" means the lower boundary of the atmosphere. "longwave" means longwave radiation. "Upward" indicates a vector component which is positive when directed upward (negative downward). Net upward radiation is the difference between radiation from below (upwelling) and radiation from above (downwelling). In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics.
