Global diabatic heating during FGGE SOP-1 and SOP-2With the increase in the observational data provided by FGGE and the use of global circulation models with full physics for the data assimilation, it is now becoming feasible to attempt to estimate globally the atmospheric diabatic heating. The thermodynamic equation in isobaric coordinates and the data generated by the FGGE III-b analysis of the Goddard Laboratory for Atmospheres (GLA) are employed to serve this purpose. The results of the present study generally agree with other previous investigations. However, some important differences are also revealed. (1) The diabatic heating obtained in the tropics in the present study is larger than that obtained elsewhere; (2) the relatively large heating over the mountainous areas shown in other studies does not appear; (3) no significant negative values of diabatic heating are found in the polar regions; and (4) unlike other studies, cooling is noted over parts of Eurasia in the summer.
