Weather and climate know no borders. The International Satellite Cloud Climatology Project (ISCCP) was set up in 1983 and pioneered the use of GEO-Ring data by combining measurements from all geostationary satellites above the Earth’s equator for studying cloud climatology. The aim was to make first global cloud assessments and to coordinate research on cloud products and their use in climate models. First GEO-Rings provided 3-hourly data from two channels. Nowadays, the GEO-Ring can provide data every ten minutes for about ten common channels.
Concerted efforts of satellite agencies are ongoing to produce GEO-Ring fundamental climate data records by addressing consistent quality control and recalibration, which will be the basis for the gridded level-1 radiance (L1g) data record. Since its first workshop in 2019, the project has generated a test L1g data record, by combining measurements from all geostationary satellites that were operating in 2021 and 2023, which is hosted by the University of Wisconsin / Cooperative Institute for Meteorological Satellite Studies (CIMSS). Multiple groups have been using this data to demonstrate its usefulness to derive geophysical parameters such as clouds and aerosols which will be presented at the workshop.
This workshop will review the progress made by the project and gather feedback from data users to finalise plans for the first routine production of GEO-Ring L1g radiance data record.
This event, organised and hosted by EUMETSAT at its headquarters in Darmstadt, is open to members of the GEO-Ring project upon invitation only.
