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
