-heat transfer and energy budgets: -basics: warmer regions radiate more energy than cooler regions, thus, there is a net transfer of radiation from warmer to cooler regions (ex. air is transparent to IR locally but absorbs increasing proportions of IR over broader scales); heat always moves from where it is warmer to where it is cooler, thus, there is a transfer of heat energy to regions that are cooler -radiation transfer-net radiation (Q*) is the amount of radiation available to warm a medium; local radiation budget (Q*=[incoming shortwave – outgoing shortwave] + [incoming longwave – outgoing longwave]); if Q*>0 net energy gain and temp. increase, if Q*<0 net energy loss and temp. fall, if Q*=0 radiation balance and no temp. change; factors control values of incoming shortwave (cloud cover, air pollution/ particulate matter, ozone layer), outgoing shortwave (type of surface, albedo, vegetation), incoming longwave (temp. of atmosphere, clouds), outgoing longwave (temp. of surface); Q* most negative at sunset, most
