The 15-year data set from the Earth Radiation Budget Experiment (ERBE) wide field-of-view (WFOV) radiometer aboard the Earth Radiation Budget Satellite (ERBS) includes the ScaRaB-1 time period. The ERBS was launched on October 4, 1984 into a 611 km orbit with an inclination of 57 degrees. This orbit precesses through all local times every 72 days and the ERBE instrument has temporal sampling problems similar to those of the ScaRaB-1 instrument. However, when measurements from both instruments are combined into a single data product, it is possible to compute a set of monthly means which is more nearly complete than would be possible from either instrument alone. We use a modification of the ERBE data processing software to produce a combined ScaRaB-ERBS data product. The ScaRaB project produced instantaneous averages for 2.5 degree regions, while the smallest spatial resolution for regional averages from the ERBS WFOV data is 5 degrees. Thus the first step in producing our combined product is to nest the ScaRaB 2.5 degree regions into 5.0 degree regions. We describe the results of combining the ScaRaB-1 and ERBS measurements to provide monthly-mean regional results.
