The purpose of this article is to assess geographical differences that exist in the differential trends between the satellite‐based lower‐tropospheric temperature measurements and the near‐surface temperatures measured by the land and sea thermometer network. Over the period 1979–1994, a highly significant difference of 0.28°C exists between the two global data sets. Analyses presented in this paper show that most of this difference comes from tropical ocean areas, with a much smaller contribution from the mid‐latitude land areas of the Northern Hemisphere. The implications of these results to the many explanations for the differential trend between the data sets are discussed.
