GOME-2 Metop-A 1rst solar gap |
Loss of GOME-2/Metop-A solar calibration between 26/01/2018-19/02/2018:The Metop-A satellite with GOME-2 on-board is currently in drifting orbit. As a consequence there will be periods in the future during which the GOME-2 instrument will not be able to carry out its daily solar calibration measurement. The first such period will be from 26th January 2018 to 19th February 2018 (24 days). During this period, the solar mean reference spectrum provided in the Metop-A/GOME-2 level-1B product will be automatically replaced by a modelled solar spectrum using information on solar activity from Metop-B. Therefore, it is expected that the product quality of both level-1B and level-2 products might undergo slight changes during this period. Thus, there will be a risk of degraded product quality for GOME-2 Metop-A products during these days. |
IASI SO2 | May 2017 - Validation of IASI SO2 MetopA and MetopB data products |

08/12/2016 -The EUMETSAT Council agreed that the ageing, but still healthy, Metop-A satellite will be exploited on a “drifting” orbit from June 2017 onwards, in order to extend its useful lifetime from 2019 to 2022. See the press release here. |

Since 15th July 2013: Metop-B/GOME-2 products are available and the measurement configuration of Metop-A/GOME-2 has been changed to the narrow swath mode (960km). Metop-B/GOME-2 instrument is measuring with in the default mode of 1920 km swath since that day. More information on tandem operations (EUMETSAT site) More information on O3M SAF L2 Metop-B products |
