The Land Surface Analysis SAF released the All Sky Land Surface
Temperature product on 16 March. The product provides radiative
temperature over land surfaces with spatial completeness due to
the combination of satellite and model data. It is derived from infrared
observations (from the Meteosat SEVIRI instrument) in cloud-free
situations and is obtained from the surface energy balance model
in cloudy conditions. A full-disc image is produced every 30 minutes
with a spatial resolution of 3-5km.
The Atmospheric Composition Monitoring SAF released a sulphur
dioxide product on 15 April. The product provides vertical profiles
of sulphur dioxide and is based on observations from the GOME-2
instrument on Metop-C. It complements operational products from
Metop-B. This product includes new volcanic flags, allowing different
source types of sulphur dioxide to be identified. The product is
validated with reference data from satellites and ground stations.

The Radio Occultation Meteorology SAF released radio occultation
products from Copernicus Sentinel-6 Michael Freilich on
16 December. The product provides vertical profiles of atmospheric
temperature, humidity, pressure and refractivity. It is based on data
from the radio occultation sensor (GNSS-RO) on the satellite. It
provides stable and controlled data for non-time-critical applications.
