RSGB archives images from AVHRR HRPT collections at the local HRPT receiving station at Bern, Switzerland (46.917° N 7.467° E). These data provide a current and complete picture of land and cloud cover for studies related to the atmosphere and surface processes. Data from the NOAA- 12, -14, -15, -17, and -18 are recorded. Image files consist of five bands within the visible, near-, middle-, and thermal-infrared spectral regions. Image spatial resolution is 1.1 km along swath centerlines, but degrades to several kilometers at the outer edges of the swaths. The sensor channel gains have 10-bit (0-1023) sensitivity and span the range of normal surface and atmospheric radiances in their respective bands. Temporal coverage begins in June 1996 for the local received HRPT images. Data reception continues through present. For the time after 1996, the frequency of spatial coverage ranges from one up to ten within 24 hours. From June 2001 on, night passes are received and archived. With foundings of the Oeschger Centers for Climate Research (OCCR) we could extent our archive to one out of three large archives in Europe.
Started in August 2002 with the launch of MSG-1 (renamed to Meteosat-8 once in orbit), the Meteosat Second Generation (MSG) program ensures the continuity of the European geostationary meteorological satellite service. A total of four MSG satellites is planned until around 2018. The primary payload of the MSG Satellites is the Spinning Enhanced Visible and Infrared Imager (SEVIRI). SEVIRI measures reflected and emitted radiance in 11 spectral channels located between 0.6 µm and 14 µm with a nominal spatial resolution of 3 km at the sub-satellite point. Additionally there is a broadband high-resolution visible (HRV, 0.4-1.1 µm) that has a 1 km spatial resolution.
