Abstract

It is widely assumed that variations in Earth's radiative energy budget at large time and space scales are small. We present new evidence from a compilation of over two decades of accurate satellite data that the top-of-atmosphere (TOA) tropical radiative energy budget is much more dynamic and variable than previously thought. Results indicate that the radiation budget changes are caused by changes in tropical mean cloudiness. The results of several current climate model simulations fail to predict this large observed variation in tropical energy budget. The missing variability in the models highlights the critical need to improve cloud modeling in the tropics so that prediction of tropical climate on interannual and decadal time scales can be improved.

The record of overlapping climate-quality satellite radiation data now extends from the Nimbus-7 mission launched in 1978 through the current Earth Observing System Terra mission launched in late 1999. Measurement of these fluxes in sufficient accuracy for climate research however is a serious challenge. Radiation fields vary greatly with spectral wavelength time latitude longitude and height from the surface of Earth; solar elevation angle; satellite viewing elevation angle; and satellite viewing azimuth angle relative to the solar plane (2). Achieving calibration accuracy of 1% or better as well as sufficient sampling of this eight-dimensional space is a major challenge to achieving data of climate accuracy of order 1 Wm −2 .
