Validation of Gomos Products Using Salomon Algorithms and Data

چکیده
The UV-visible spectrometer SALOMON, dedicated to the retrieval of vertical profiles of O3, NO2 and NO3, has performed measurements on 19 September 2002, from Aire sur l’Adour (France) between 20h00 and 22h30 TU. At the same time, an ozone sounding has been launched. GOMOS has performed measurements at 21h24 UT, with a spatial coincidence with SALOMON and the sounding of around 250 km. Then, all these sets of measurements can be directly compared. The GOMOS ozone vertical profile exhibits an overestimation in the middle stratosphere, and the NO2 and NO3 profiles are unrealistic. Using the algorithms developed for SALOMON, new slant column profiles are derived from GOMOS transmissions, as well as new vertical profiles. This time, the agreement between SALOMON profiles and these new profiles is excellent. Then, recommendations for algorithm improvements are proposed.

متن کاملEarly Validation of Vertical Profiles from the Envisat Atmospheric Instruments Gomos and Mipas with the University of Bonn Lidar at the Esrange in July and August 2002
The vertical structure of the terrestrial atmosphere is governed by hydrostatic equilibrium, which relates altitude, temperature, and pressure (or density). The mixing ratios derived for the chemically important trace gases depend on a precise knowledge of this basic atmospheric structure. The Bonn University backscatter lidar on the Esrange (68N, 21E) near Kiruna, Sweden, was operated from mid...
متن کاملValidation of Gomos Ozone Profiles Using Ndsc Lidar: Statistical Comparisons
The lidars deployed in the NDSC framework have been used for the validation of GOMOS onboard ENVISAT. During the commissioning phase around ten coincidences per site have been investigated. No significant bias, larger than ±5%, has been reported except around 50 km and 20 km where both techniques are known to present some limitations. The estimated errors of both GOMOS and lidar are in good agr...

G-POD provides an efficient and highly collaborative environment to faster process and interpret large amounts of Earth Observation (EO) data. It combines storage and computing elements, which are located in different geographic locations and combines th...
متن کاملGOMOS ozone profile validation using ground-based and balloon sonde measurements
The validation of ozone profiles retrieved by satellite instruments through comparison with data from groundbased instruments is important to monitor the evolution of the satellite instrument, to assist algorithm development and to allow multi-mission trend analyses. In this study we compare ozone profiles derived from GOMOS night-time observations with measurements from lidar, microwave radiom...
