Weather and methane satellite MetOp-SG-A1 launched

On August 12 late at night, ESA has launched the European MetOp-SG-A1 satellite from its base in French Guiana. The partly Dutch Sentinel-5 instrument onboard is an addition to the already active Sentinel-5p/TROPOMI satellite. SRON has contributed the immersed grating for both and developed the software tools to derive methane and CO data from the observations.
