Discrepancies between Nimbus-6 satellite and weighted rawinsonde data on 25 August 1975 and 3 September 1975 are examined over four geographical areas. Good agreement between satellite and weighted linearly interpolated rawinsonde temperature and temperature-derived parameters was found in most instances, with the poorest agreement either near the tropopause region or near the ground. However, satellite moisture data are highly questionable. The smallest discrepancy between satellite and weighted mean rawinsonde temperature and parameters derived from temperature was found over water, and the largest discrepancy was found over mountains. Cumulative frequency distributions show that discrepancies between satellite and rawinsonde data can be represented by a normal distribution except for dew-point temperature. Author
