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