Question
Please help with these questions!!! Figures 7 and 8 below show the net surface radiation at Maun on March 19th and September 24th in 2000. The energy from surplus surface radiation can be used to heat the atmosphere via conduction and convection (sensible heat flux = H), heat the ground (soil heat flux = G), or evaporate moisture (latent heat flux = L). Think of the ‘surface’ as a very thin layer of soil (or other substrate) where energy continually fluxes into or out of by R, H, G, & L. In Figures 7 & 8, positive values of R, G, H, and L indicate an energy gain for the surface whereas negative values indicate an energy loss by the surface. Remember that with conduction and convection, heat flows from hot to cold. For example, when G is positive (a gain for the surface), the ground beneath the surface must be warmer than the surface itself.
Question 15) Would you expect incoming shortwave radiation at the top of the atmosphere to be fairly similar or quite different for this location on these two dates?
Question 16) Which date shows more evidence of clouds?
Question 17) On which date would you expect the dewpoint to be higher at 2pm, only considering local moisture sources?

15. Net radiation=absorbed solar+ net longwave.The incoming shortwave radiation at the top of the atmosphere is quite different for this location on these two dates. Shortwave radiation is reflected by clouds and absorbed by the atmosphere.If there are larger part of aerosol then the shortwave radiation gets absorbed and gets emitted as longwave.As shown in figure there is more emittance in september 24 than the other day, which indicates there is difference in shortwave radiation absorbed at the top of the atmosphere(toa).
16. .The radiative cooling of the atmosphere is primarily balanced by latent heat release in fprecipitaing cloud systems.March 19 shows more latent heat than that of September 24.Hence March 19 shows more evidence of clouds.
17.Spetember 24 would have dewpoint higher at 2pm, since the sensible heat of the atmoshpere to is more on this day.
