Abstract

Trends in global lower tropospheric temperature derived from satellite observations since 1979 show less warming than trends based on surface meteorological observations. Independent radiosonde observations of surface and tropospheric temperatures confirm that, since 1979, there has been greater warming at the surface than aloft in the tropics. Associated lapse-rate changes show a decrease in the static stability of the atmosphere, which exceeds unforced static stability variations in climate simulations with state-of-the-art coupled ocean-atmosphere models. The differential temperature trends and lapse-rate changes seen during the satellite era are not sustained back to 1960.

1. Precise Monitoring of Global Temperature Trends from Satellites

2. Trends in globally averaged temperatures for the most recent version (d) of the MSU data for the period 1979–97 are −0.04 K decade −1 for the mid troposphere (MSU 2) and −0.01 K decade −1 for the lower troposphere (MSU 2LT). The previous version (c) yields trends of +0.01 K decade −1 (MSU 2) and −0.04 K decade −1 (MSU 2LT). Trends for the tropical belt (30°N to 30°S) are −0.01 K decade −1 (MSU 2) and −0.07 K decade −1 (MSU 2LT) for version d and +0.03 K decade −1 (MSU 2) and −0.10 K decade −1 (MSU 2LT) for version c. The two versions differ in that d includes adjustments for satellite orbital decay (6) diurnal sampling drift and instrument-body temperature effects as discussed by J. R. Christy R. W. Spencer and W. D. Braswell [ J. Atmos. Oceanic Tech. in press]. The studies cited in (6) (7) (14) and (16) use version c or an earlier version of the MSU data.
