SCIAMACHY M-factors: News


Top 17 August 2015

  • One m-factor archive for the whole mission has been added to the download page.

Top 09 May 2012

  • The communication with the Envisat satellite was lost 8 April 2012. After one month of attempts to recover ENVISAT following the anomaly from April 8th, ESA has today declared the ENVISAT mission ended.

Top 30 November 2010

  • M-factor plots for the last 4 weeks and median plots for the measurements used in the m-factor calculation are added to the web-page.

Top 10 November 2010

  • EnviSat has successfully changed the orbit with three manoeuvres from 22 October to 4 November 2010.
  • The new orbit required a S/W update in the m-factor setup. Unfortunately, the first version of the update introduced a problem with the validity start time of the m-factor files:
     25 Oct - 01 Nov: The validity start time is ~1.5 days before the measurements.
     02 Nov - 07 Nov: The validity start time is ~0.5 days before the measurements.
     08 Nov onwards: The validity start time in nominal mode
    No impact for users is expected, because changes in m-factors in this time range are not significant.

Top 08 April 2010

  • NRT m-factors contained erroneous values for channel 6,7, and 8 for the time frame 04 February 2010 - 6 April 2010. They are today replaced by corrected versions.
  • The V7.01 database has been extended to 08 February 2010, covering now the complete period for the upcoming re-processing of SCIAMACHY data.

Top 18 March 2010

  • V6.01 are now complete in the m-factor data base. The NRT V6.01 are therefore removed from this page.

Top 04 February 2010

  • Release of V7.01 m-factors, aligned with the NRT V7 L0-1b processor activation.
  • First NRT V7.01 m-factors will be available 09 February 2010.

Top 08 April 2008

  • Release of V6.01 m-factors.
  • Availability of NRT m-factors.

Top 17 July 2007

  • First release of m-factor data (V6.00) and accompanying documentation for impact studies.

Top 13 June 2007

  • First version of m-factor web pages (still under construction).
