@EUMETSAT has officially taken command of the Meteosat Third Generation Sounder 1 (#MTGS1) – Europe’s first-ever geostationary sounder satellite. https://t.co/XbSheds543

The monthly AMV monitoring web pages have been updated to include O-B plots against the DWD global model background. Please visit the @NWP_SAF pages for details: https://t.co/R2L2BDZAvB

Platform assemble! 🦸‍♀️🦸‍♂️ The ALTIUS satellite platform has been assembled at Redwire's facilities, Belgium. It is the technical backbone of the satellite, responsible for power supply and management, thermal regulation, navigation, attitude pointing and orbit control, and more.

📢The @NWP_SAF teams are please to announce the release of the Radiance Simulator version 4 🌐🌍🛰️. RadSim v4 comes with numerous improvements and new features, for additional details please visit https://t.co/V5tBv3Mil1

On 1 July, the 108ᵗʰ EUMETSAT Council approved the updated SAF Strategy — a major step to keep the SAF Network agile, innovative, and user-focused. It introduces an Innovation Layer, supports EU activities, and enables open-source licensing for SAF software.

Signal acquired, #MTGS1 says hi! 👋 Launch and communication established with our new addition in space. This is a huge moment for all teams involved - now we wait for solar array deployment 🛰️

And there they go! 🛰️ MTG-S1 and @CopernicusEU Sentinel-4 have separated from @SpaceX’s Falcon 9 and are now flying solo. We have also received acquisition of signal📡

Following the recent release of the new dataset of 100,000 atmospheric profiles from CAMS, Emma Turner (ECMWF) has kindly prepared a fantastic Feature Article on the subject: https://t.co/cIhYfAzHgQ Good read!

📢A new extra-large set of diverse atmospheric profiles has recently been compiled by the NWP SAF and is now available to the scientific community for the first time in nearly 10 years! https://t.co/oOzEfJX0V4

The free webinar (@crews Central Africa) Training on hydrometeorological variability - EUMETSAT H-SAF Soil Moisture Products Programme will be held on monday 5th May. @WMO @eumetsat_users https://t.co/zEIpeqQvsA

The @NWP_SAF 11th Analysis Report of the AMV monitoring has been released and is available from our website. The analysis reports identify features from the monitoring statistics and document how these evolve over time. Details on https://t.co/esFbqnrwDh

The @NWP_SAF monitoring pages have been enhanced to include Meteosat 12 (MTG-I1) near real-time (NRT) radiance quality monitoring and Atmospheric Motion Vector (AMV) monthly monitoring. For details, please visit https://t.co/CfgTmEkt2D

Exciting news! 🤩 @eumetsat teams are looking forward to launching and operating our next-gen, polar-orbiting satellites. 🛰️ Once fully deployed they will provide detailed global observations of the atmosphere, oceans & land. Find out more:
