"Gomos Validation: Air-density and temperature profiles"
Earth and related Environmental sciences
MetadataShow full item record
Lidar system and radio-soundings were used to validate both air-density and low and high-resolution temperature profiles of the GOMOS instrument onboard ENVISAT-1 satellite. No bias greater than 7% was found for the air-density comparisons with lidar and there is a very strong global agreement. The conditions of the occultations have a large impact on the comparisons concerning the temperature profile. The “dark limb” measurement conditions show great agreement between 35 and 60 km with no bias greater than 5% whereas the “bright limb” measurement conditions show poor results. The High Resolution temperature shows a very interesting potential.
