... - I where S is the solar insolation, or is the planetary albedo, and I is the outgoing longwave radiation emitted by Earth to space. The goal of ERB measurement programs is to provide observations of the space and time distributions of both or and I and usually S as well (Wielicki et al., 1995~.

... satellite (Wielicki et al., 1996~. The measurement approach of CERES is ostensibly the same as that of ERBE, with advances in the improved angular sampling and cloud classification that reduce the monthly mean flux error to 1 or 2 Wow.

... So far, only the broadband shortwave ERB measurements have demonstrated sufficient calibration accuracy and stability. · Averages of TOA fluxes and surface fluxes, at climate time and space scales, are expected to be closely related for shortwave fluxes (approximately linear)

... In the CERES era, this will include a combination of measurements from the AM and PM satellites as well as from the processing TRMM satellite. Simulations of the sampling errors in TOA fluxes that are due to undersampling by a single satellite and by combinations of all three satellites demonstrate how these errors can be systematically reduced by adding temporal sampling provided by measurements from two and three satellites.

... Second, unlike low-Earth-orbiting satellites, the geostationary satellite view limits the climate observations for any given region of Earth to a single viewing zenith angle. This limitation causes an even larger dependence on angular model corrections and will increase the angular sampling errors shown in Table 9.1.

... Current ERB satellite measuring programs provide useful information about the TOA fluxes, but this information has its limitations, two of which follow: 1. Progress toward confirming our estimates of radiative forcing of climate requires careful monitoring of the radiation budget.
