Abstract
The outgoing longwave radiation is an indicator of the overall state of the Earthatmosphere system and its diurnal variation reveals how the system responds to the solar diurnal forcing. The Earth Radiation Budget Experiment (ERBE) is the first attempt to use a multi-satellite system to obtain improved time sampling necessary for determining diurnal variation. We have used 3-hourly Meteosat data to improve the time sampling still further as compared to the four observations per 24 hours obtained during most of the ERBE lifetime. Regression techniques and radiative transfer calculations allow us to convert the relatively narrow-band Meteosat infrared window (IRW: 11 pm) and water vapor (WV: 6. 3 m) channel data into estimates of broad-band longwave (LW) radiant exitances. We compare the diurnal variations obtained from these data with the ERBE diurnal cycle estimates. Results show that the ERBE diurnal modelling algorithms generally perform very well and that most of the discrepancies that are observed would not have occurred if the system had been complete with scanners functioning together on 3 satellites as originally planned. 1.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering.
