The Institut Royal Meteorologique de Belgique ( RMIB ) and its On Line Short-term Service ( ROLSS ) provides near real-time Level 2.0 (radiances and fluxes) data from the GERB instruments. This FTP site aims to provide data to the user community within less than 4 hours. The data are automatically removed from the site after 40 days. The long term archive is hosted on the GERB Ground Segment Processing System, located at the Rutherford Appleton Laboratory. Therefore, this page provides the minimal information needed to access the near real time data from the GERB instruments.
