Slight discrepancies were seen in the monthly means from the two data sets, and possible causes were discussed. All TISA subsystems are on target for delivery to meet TRMM schedules. These algorithms are still in the development stage. IBM Explorer is an effective visualization tool, especially for global data. Computed fluxes are consistently higher than measured fluxes for clear-sky conditions.
Further work is needed to clarify absolute accuracy of the different surface radiation sensors.
The new methodology requires only a single pass through the observations to analyze the cloud properties. The new ADMs eliminated albedo growth to the limb, reduced latitudinal bias, and reduced cloud cover growth with viewing zenith. However, the monthly global flux was almost unchanged. At least 6 different mathematical definitions are in the literature. Cloud heights are assumed in accordance with the International Cloud Atlas.
