The short-term m-factor data base consists of an archive
of daily
m-factor files. Each m-factor file is an ASCII file
formatted according
to the ENVISAT Product Specification.
The data base covers the whole mission: 02-Aug-2002 until 12-Feb-2012.
The m-factor version is 7.01, valid for Level 1b products version 7.xx. Click here for the release notes.

These data are no longer needed!
NRT (near-real-time) M-factors are calculated based on NRT Level 1b data products. They are (usually) released once per week. Each release adds calculated m-factor files for the previous week and predicted m-factor files for the following week to the database. The predicted m-factors will not be choosen by the applicator, if calculated m-factors already available. Each release goes along with a delivery document (MF_delivery_yyyymmdd.pdf).
Click here to enter the directory with NRT m-factors, valid for Level 1b products version 7.xx. The m-factor files itself are in the subdirectory V07.01. The delivery documents are in the subdirectory Delivery_document_07.01.
NRT m-factors contained erroneous values for channel 6,7, and 8 for the time frame 04 February 2010 - 6 April 2010. They are replaced by corrected versions 08 April 2010.
M-factors may be applied to SCIAMACHY Level 1b products
using an
appropriate applicator software. The following software is
available
for this purpose:
