Abstract

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 dataset was produced by Anu Dudhia, University of Oxford and National Centre for Earth Observation (NCEO).

Data lineage:

03-JUN-2010: Version 1.02-1.10 data provided to NEODC in netCDF format by Anu Dudhia(Oxford) as an output from the NERC National Centre for Earth Observation

28-JUN-2011: Minor changes were made by Victoria Bennett (NEODC) to netCDF variable attributes (long names) as long names did not match correct variables in original files

04-AUG-2011: Version 1.2 Data added to archive. Data submitted by Anu Dudhia, University of Oxford

19-JUL-2012: MIPAS-Oxford archive separated out from the main MIPAS archive for catalogue records consistency.

Data Quality:
Operational data.
File Format:
Data are netCDF formatted

Title MORSE MIPAS retrieval processor deployed on Oxford Computer
Abstract This computation involved: MORSE MIPAS retrieval processor deployed on Oxford Computer. MORSE (MIPAS Orbital Retrieval using Sequential Estimation) is a FORTRAN77 program developed under NERC's Earth Observation Enabling Fund to allow (mainly) UK groups to perform their own retrievals of atmospheric profiles from MIPAS spectra. The program was developed by Anu Dudhia, University of Oxford. Metadata document Metadata document
