MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) is a Fourier transform spectrometer (FTS) on the Envisat satellite, used for high resolution limb sounding of emission in the infrared region between 4.15 and 14.6 microns. The species covered by MIPAS are O3, H2O, CH4, N2O, HNO3, NO2, CFC-11, CFC-12, ClONO2, N2O5.
Although the ENVISAT mission has been declared as ended by ESA after the sudden loss of the Envisat platform, on the 8th of April 2012, efforts on algorithm development and reprocessing are still continued and improved datasets will be provided to the users.
The Level 1b reprocessing of the full MIPAS mission (from 2002/07/01 up to 2012/04/08, including the Full Resolution and the Optimized Resolution mission phases), using the ESA Instrument Processor Facility (IPF), has been completed following delivery of V7.11 of the IPF after preliminary processing with V7.10. Further delta L1 reprocessings have been performed, and the dataset released to users. This has been followed by the complete L2 reprocessing.
The reprocessing was performed by the eXpert Product Reprocessing Scalable Service X-PReSS consortium under ESA management.
The progress of the different activities is summarized in the figure above.
