Pertaining to Lab 3 Q14, why is the peak net radiation approximately the same on the two dates seen in figures 3-5 and 3-6? The weather conditions must have been the same on those dates (i.e. clouds, pressure, temperature, etc.) The data for both days must have been taken on surfaces with the same albedo Botswana is right on the equator so it has very little variation throughout the year The latent heat, sensible, heat, and soil fluxes when averaged together are about the same on both days The sun angles are similar on both dates

Pertaining to Lab 3 Q14, why is the peak net radiation approximately the same on the two dates seen in figures 3-5 and 3-6?
The weather conditions must have been the same on those dates (i.e. clouds, pressure, temperature, etc.) |
||
The data for both days must have been taken on surfaces with the same albedo |
||
Botswana is right on the equator so it has very little variation throughout the year |
||
The latent heat, sensible, heat, and soil fluxes when averaged together are about the same on both days |
||
The sun angles are similar on both dates |

Transcribed Image Text:Surplus net radiation at the surface can be expended
in three general ways:
sensible heat flux to the atmosphere (energy
expended in heating the air at Earth's surface),
soil heat flux (energy expended in heating the
soil)
latent heat flux (energy used in evaporating
moisture from the surface).
Figures 3-5 and 3-6 show the net surface radiation
at Maun on March 19, 2000, and September 24, 2000,
respectively.
