General Problems

• Missing data in 1985-86: Almost half of the ISCCP cloud data were missing during 1985-86 (only one NOAA satellite available), so the flux results are almost certainly biased.
• Fluxes too small: Through comparisons with monthly and daily station data and fluxes generated by a climate model, it appears that the downwelling longwave flux at the surface may be too small. For higher sun conditions the downwelling shortwave flux may also underestimate the true flux. This potential problem is under investigation.
