    Space data support Earth’s ecosystems

    ESA’s Earth observation (EO) missions are making a critical contribution to monitoring transformations in our planet’s ecosystems, helping track changes in the vegetation, soil, and ocean that affect these systems.

    Space and the Arctic 2009 Workshop

    Temperatures in the Arctic are rising at an unprecedented rate. This workshop looked at the needs and challenges of working and living in the rapidly changing Arctic and explore how space-based services might help to meet those needs.

    SMOS L3 Sea Ice Thickness

    The SMOS Level 3 Sea Ice Thickness product, in NetCDF format, provides daily estimations of SMOS-retrieved sea ice thickness (and its uncertainty) at the edge of the Arctic Ocean during the October-April (winter) season, from year 2010 onwards. The sea ice thickness is retrieved from the SMOS L1C product, up to a depth of approximately 0.5-1 m, depending on the ice temperature and salinity. Daily maps, projected on polar stereographic grid of 12.5 km, are generated by the Alfred Wegener Institut (AWI). This product is complementary with sea ice thickness measurements from ESA's CryoSat and Copernicus Sentinel-3 missions.

    SMOS - CryoSat L4 Sea Ice Thickness

    The SMOS-CryoSat merged Sea Ice Thickness Level 4 product, in NetCDF format, is based on estimates from both the MIRAS and the SIRAL instruments with a significant reduction in the relative uncertainty for the thickness of the thin ice. A weekly averaged preliminary product is generated every day by the Alfred Wegener Institut (AWI) by merging the weekly CryoSat Sea Ice Thickness product and the daily SMOS Sea Ice Thickness retrieval. A final product is provided with a latency of about 3-4 weeks using a different global sea ice concentration product and a reprocessed CryoSat product. All grids are projected onto the 25 km EASE2 Grid based on a polar aspect spherical Lambert azimuthal equal-area projection. The grid dimension is 5400 x 5400 km, equal to a 432 x 432 grid centered on the geographic pole. Coverage is limited to the October-April (winter) period for the Northern Hemisphere, due to the melting season, from year 2010 onwards.

    Satellite data central to ocean monitoring

    Over 95% of Earth’s water is found in our oceans, and yet sadly, oceans are under stress from climate change and pollution. Monitoring our oceans is vital for Earth’s survival and satellites are the primary means of long-term and independent observation of our vast ocean bodies and their associated coastal zones.

    Satellite data boost global understanding of land surface

    Understanding our changing land surface is essential in the study of climate change. Satellites are used to monitor changes to the material that covers Earth’s surface, so-called land cover, such as vegetation and water.

    Overachieving SMOS mission primed for continued success

    ESA’s Soil Moisture and Ocean Salinity mission (SMOS) was the second Earth Explorer launched in 2009. Over 13 years on, having already vastly exceeded its predicted lifetime and initial objectives, the mission has been further extended until at least the end of 2025.
