Jason was part of team that had to calculate the incoming solar radiation and outgoing terrestrial infrared radiation. what did jason’s team study?

Heat budget of the earth.

Explanation:

The heat budget is defined as the balancing of heat energy between the incoming solar radiation that is captured by the earth and the released heat from the earth into the outer atmosphere in the form of radiations. This heat budget helps in maintaining an average temperature on earth. When this heat budget is not in equilibrium, then it adversely affects the climate on earth, leading to an extensive increase or decrease in the earth's global temperature.

Thus, when Jason and his team calculated the incoming solar and outgoing terrestrial infrared radiation, they actually studied the earth's total heat budget.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
