Switch from Meteosat-8 to Meteosat-9 over Indian Ocean planned on 23 June

Meteosat-8 (IODC for Indian Ocean Data Coverage), providing coverage of the Indian Ocean from the geostationary orbit in position 41.5°E, will be replaced by Meteosat-9 in 45.5°E in OSI SAF products on the 23 of June around 08:00 UTC.

Please note that Meteosat-9 will cover the area between 14.5°E and 105.5°E, instead of 18.5°E to 101.5 °E for Meteosat-8. We are confident that the quality of the product will be as good as before but the file_quality_level will be set to 0 (unknown quality) until the validation of the products can be fully performed.

Tests files based on Meteosat-9 are available on the LML FTP server hosted by Ifremer, in the same directories as products based on Meteosat-8 (in the sub-directories 2022/158):
