We found that the seasonal variation of water vapor are strongly correlated to that of long-wave downward radiation while the CO_2 concentration are uncorrelated to the long-wave downward radiation.The long-wave upperward radiations of H_2O and CO_2 are discussed by compairing the collision relaxation time and the re-radiation relaxation time of molecules., 紀要論文}, pages = {9--17}, title = {日本域における下向き赤外放射と温室効果ガスの相関}, year = {2014} }
