To ensure that the end-user needs are met, EUMETSAT maintains the quality of its operational products through the continuous assessment and evolution of its scientific algorithm baselines.
As an example, the Polar Multi-sensor Aerosol product (PMAp) provides daily satellite-derived measurements of aerosol optical depth (AOD) over the land and oceans. Aerosols are solid or liquid particles in the atmosphere (e.g. smoke or dust) and AOD is the used to identify the amount of aerosols in the atmosphere.
PMAp was developed at EUMETSAT and is based on a retrieval algorithm that that combines measurements from three Metop instruments: Global Ozone Monitoring Experiment (GOME-2), Advanced Very High-Resolution Radiometer (AVHRR), and Infrared Atmospheric Sounding Interferometer (IASI).
