(Presenter)
The European Space Agency (ESA) acquires and distributes MODIS Aqua and Terra products as a Third Party Mission (TPM). Data is acquired over Europe via Direct Broadcast at the Matera (Italy) and Maspalomas (Gran Canaria) receiving stations and used to populate the MERCI MODIS and MyOcean Catalogues, available to Users in Near Real Time (NRT). MyOcean forms the marine branch of the Global Monitoring for Environment and Security (GMES) initiative; a European Union (EU) led programme aimed at the establishment of a European capacity for Earth Observation. GMES consists of a set of systems which collects data from multiple sources (satellite and in situ) making it available to policy makers and public authorities to aid environmental decision making, with a particular focus on climate change. Through conformation to Quality Assurance for Earth Observation (QA4EO) guidelines, GMES aims to form part of the Group on Earth Observations (GEO) vision for a Global Earth Observation System of Systems (GEOSS), providing near-real-time environmental data, information and analysis worldwide. ARGANS Ltd is a company based in Plymouth UK, which under the VEGA-lead IDEAS SPPA service, performs routine quality control and handling of ESA MODIS data; this includes product processing using the SeaDAS processor, regular reporting, help to User queries, and on demand anomaly investigations . In addition, following the cessation of the SeaWiFS mission in December 2010, plans to reprocess ESA archives of SeaWiFS data using the most recently available NASA code and calibration configurations (available via SeaDAS 6.2) are imminent. A research effort aimed to increase awareness of ESA acquired MODIS and SeaWiFS data products is also under consideration; the project aims to make comparisons between ESA and NASA atmospheric correction schemes through the analysis of MODIS, SeaWiFS and MERIS data alongside NOMAD and AERONET-OC match-ups.
