Global upper tropospheric relative humidity over ice observed by MIPAS


The above figure shows global upper tropospheric relative humidity observed by MIPAS from 6 November to 7 December 2005.

A global distribution of upper tropospheric relative humidity over ice (RHi) observed by MIPAS is shown. MIPAS RHi profiles are computed from MIPAS temperatures and H2O profiles using the Goff and Gratch (1946) formula. In the tropics at approximately 100 hPa supersaturation is observed.
