| - | This field gives the quantity of the incoming solar radiation which is reflected by the Earth-atmosphere system. The higher values for the solar reflected flux are observed over optically thick cloud cover located close to the Sun-subpoint where the illumination is maximum. The physical unit for this quantity is the Watt per square meter (W/m2). In the GERB data file, the solar flux is quantify using a quantification factor 0.25 W/m2. An animation showing the variation of the solar reflected flux for a 48-hour period is available [[http://gerb.oma.be/gerb/LastImages/anim_sol_flux.gif|here]]. | + | This field gives the quantity of the incoming solar radiation which is reflected by the Earth-atmosphere system.

| - | This field gives the quantity of energy thermally emitted by the Earth-atmosphere system. The higher values for the thermal flux are observed over hot desert areas under clear sky conditions. Clouds usually cause a decrease of the thermal emission from the Earth to the space (greenhouse effect of clouds). The physical unit for this quantity is the Watt per square meter (W/m2). In the GERB data file, the thermal flux is quantify using a quantification factor 0.25 W/m2.
