  • On 1 April 1960, NASA sent the Television Infrared Observation Satellite (TIROS-1) into space. TIROS-1 was developed during the 1950s and, after years of experimental programmes and attempts, became the world’s first weather satellite. Since weather satellites were a new technology at that time, the mission also tested various design issues for spacecraft, such as instruments, data, and operational parameters, in order to improve satellite applications for Earth-bound decisions. TIROS-1 thus paved the way for further weather satellite development and research. Today, weather satellites provide highly accurate and near-real-time measurements that can efficiently monitor and forecast extreme weather events, such as floods and droughts, as well as enhance the understanding of the climate and of the Earth as a whole.

  • The European Centre for Medium-Range Weather Forecasts (ECMWF), after months of careful testing, has started to operationally assimilate data from the European Space Agency's Aeolus satellite in its daily weather forecasts. Aeolus measurements have been considered ready for operational use as early as 14 months after the satellite launch, which is unusual for data collected from a new type of satellite. Aelous provides accurate and near-real time measurements that can improve weather forecasting and contribute to better preparedness for possible hazards.

    The Aeolus satellite is the first of its kind as it is able to calculate atmospheric winds in cloud-free areas or winds throughout vertical wind columns. To date, satellites could estimate winds only from the movements of...

  • The Global Ecosystem Dynamics Investigation (GEDI) produces high resolution laser ranging observations of the 3D structure of the Earth. GEDI’s precise measurements of forest canopy height, canopy vertical structure, and surface elevation greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. GEDI’s data on surface structure are valuable for weather forecasting, forest management, glacier and snowpack monitoring, and the generation of more accurate digital elevation models.
  • ESA's Earth Observation Thematic Exploitation Platform (TEP) is a browser for satellite imagery and specific products on an environmental topic. The TEP platforms are divided into 7 categories: Coastal; Forstry; Geohazards; Hydrology; Polar; Urban; and Food Security. Each platform is a collaborative, virtual work environment providing access to EO data and the tools, processors and Information and Communication Technology resources required to work with them. TEP aims to bridge the gap between the users and the data and tools.
