1973-1996 Trends in depth-averaged tropospheric temperature

Stratospheric and tropospheric SSU/MSU temperature trends

Analysis of spatial distribution in tropospheric temperature trends

[1] Regional patterns in tropospheric and sea surface temperature (SST) trends are examined for the period 1979 – 2001 using MSU, NCEP-NCAR, ECMWF reanalyses, NOAA OI SST, and the CARDS radiosonde data set. Trends are estimated using a nonparametric approach. Substantial regional variability in temperature trends is seen in all data sets, with the magnitude of the variability (including substan...

Satellite-derived vertical dependence of tropical tropospheric temperature trends

[1] Tropical atmospheric temperatures in different tropospheric layers are retrieved using satellite-borne Microwave Sounding Unit (MSU) observations. We find that tropospheric temperature trends in the tropics are greater than the surface warming and increase with height. Our analysis indicates that the near-zero trend from Spencer and Christy’s MSU channel-2 angular scanning retrieval for the...

Disparity of tropospheric and surface temperature trends: New evidence

[1] Observations suggest that the earth’s surface has been warming relative to the troposphere for the last 25 years; this is not only difficult to explain but also contrary to the results of climate models. We provide new evidence that the disparity is real. Introducing an additional data set, R2 2-meter temperatures, a diagnostic variable related to tropospheric temperature profiles, we find ...

Tropospheric temperature trends: history of an ongoing controversy

Changes in atmospheric temperature have a particular importance in climate research because climate models consistently predict a distinctive vertical profile of trends. With increasing greenhouse gas concentrations, the surface and troposphere are consistently projected to warm, with an enhancement of that warming in the tropical upper troposphere. Hence, attempts to detect this distinct ‘fing...
