This dataset contains atmospheric profiles from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on Envisat, processed with the Oxford L2 retrieval algorithm MORSE. This differs from the European Space Agency L2 products in that it uses an optimal estimation approach rather than a regularised least squares fit, and has additional molecules. The L1B spectra are made available by ESA approximately 2 weeks after acquisition and L2 processing takes another week or so depending on the number of orbits and observation mode.
The dataset was produced by Anu Dudhia, University of Oxford and National Centre for Earth Observation (NCEO).
In the first processing version (v1.00-1.10) the following L2 products are generated: pT, H2O, O3, HNO3, CH4, N2O, NO2 (ie the ESA products), plus CFC-11, CFC-12, ClONO2, N2O5 and CO. However for the Middle Atmosphere (MA) and Upper Atmosphere (UA) mode data, only the ESA products plus CO are produced.
