  1. Data Status and Validation Temperature John Gille

  2. Conclusions • HIRDLS temperatures are within 1-2K warmer than sondes and ECMWF temperatures from 100 - ~ 5hP (cooler above and below) • HIRDLS appears warm at the tropical tropopause by 1-2 K • HIRDLS temperatures ± 2K from 300-1 hPa • Precision 0.5-0.8K between 100 - 1 hPa • No variation of accuracy with latitude • No discernable drift with time

  3. Conclusions
