英文摘要: In recognizing the importance of Stratospheric Sounding Unit (SSU) onboard historical NOAA polarorbiting satellites in assessment of long-term stratospheric temperature changes and limitations in previous available SSU datasets, this study constructs a fully documented, publicly accessible, and well-merged SSU time series for climate change investigations. Focusing on methodologies, this study describes the details of data processing and bias corrections in the SSU observations for generating consistent stratospheric temperature data records, including 1) removal of the instrument gas leak effect in its CO 2 cell; 2) correction of the atmospheric CO 2 increase effect; 3) adjustment for different observation viewing angles; 4) removal of diurnal sampling biases due to satellite orbital drift; and 5) statistical merging of SSU observations from different satellites. After reprocessing, the stratospheric temperature records are composed of nadirlike, gridded brightness temperatures that correspond to identical weighting functions and a fixed local observation time. The 27-yr reprocessed SSU data record comprises global monthly and pentad layer temperatures, with grid resolution of 2.5° latitude by 2.5° longitude, of the midstratosphere (TMS), upper stratosphere (TUS), and top stratosphere (TTS), which correspond to the three SSU channel observations. For 1979-2006, the globalmean trends for TMS, TUS, and TTS, are respectively -1.236 ± 0.131, -0.926 ± 0.139, and -1.006 ± 0.194 K decade -1. Spatial trend pattern analyses indicated that this cooling occurred globally with larger cooling over the tropical stratosphere. © 2012 American Meteorological Society. Citation statistics:
