Minimize MWR
Instrument image

The main objective of the microwave radiometer is the measurement of atmospheric humidity as supplementary information for tropospheric path correction of the radar altimeter signal, which is influenced both by the integrated atmospheric water vapour content and by liquid water. In addition, MWR measurement data are useful for the determination of surface emissivity and soil moisture over land, for surface energy budget, investigations to support atmospheric studies, and for ice characterisation.

The MWR instrument on board Envisat is a derivative of the radiometers used on the ERS-1 and ERS-2 satellites. It is a dual-channel nadir-pointing Dicke-type radiometer, operating at frequencies of 23.8 GHz and 36.5 GHz.

Envisat - MIPAS Level 1b dataset processed with IPF version 7.11 is available

22 May 2015

The Level 1b re-processing of the full MIPAS mission (from 01/07/2002 up to 08/04/2012, including both Full Resolution and Optimized Resolution mission phases) has been completed with the ESA processor IPF version 7.11. The re-processed MIP_NL__1P data has now been released to the user community and made available online for direct download via the ESA centralised dissemination service (DissHarm).
