Is alpha simply the portion of solar energy that hits the biosphere (or species) or is it that part of the solar energy reaching it that the biosphere manages to assimilate? Also, is alpha assumed to be constant or variable?
Also, is Lambda only the loss as heat of energy that has previously been assimilated by the biosphere or that loss plus the part of solar energy that is transformed into heat directly aftr having hit the the biosphere?
