Most of the radiation emitted by the earth and its atmosphere is in the category of:
infrared
Heat
is a transfer of energy from areas with high temperatures to those with low temperatures.

convection
With an increase in altitude, air pressure:
decreases at a decreasing rate
On the average, for every 1 km increase in altitude in the troposphere the air temperature:
drops about 6.5 degrees Celsius.
Objects with higher temperatures:
emit more shortwave radiation than cooler objects do.
