8. b values have been theoretically evaluated, and have been determined to be small for MSU channel 2 (0.01°C or less) on a hemispheric and global basis. Larger effects could conceivably occur over small regions. In contrast, MSU channel 4 is essentially unaffected by any of these changes. The radiative transfer theory involved in the analysis of these effects is covered in (6).
9. Low-pass filtering of the time series allows isolation of the more slowly varying temperature variations that are of interest to climatologists. Here, the filter retains 50 percent of the power of cycles having 90-day periods, progressively less power of periods shorter than 90 days, and more power of longer periods.

20. R. Jenne and D. Joseph provided the MSU data used in this study; R. Hood provided data processing and programming support; N. Grody collaborated on portions of this research and provided general advice; F. Wentz provided updated sea surface emissivity estimates; P. Olsen, F. Soltis, and P. Swanson assisted us in obtaining technical data on the MSU; G. Wilson helped obtain the satellite data sets; discussions with J. Dodge and R. McNider led to the present research.
