SMOS data reveal ecosystems' resistance to drought
Climate change is rapidly altering the world’s ecosystems, causing extreme weather conditions, such as droughts, to become increasingly frequent. Understanding the factors that contribute to ecosystem resilience to extreme events is vital to develop more effective strategies for climate adaptation and mitigation.

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.

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.

Data - Data Description
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.
Data - Data Description
SMOS Soil Freeze and Thaw State
The SMOS Level 3 Freeze and Thaw (F/T) product provides daily information on the soil state in the Northern Hemisphere based on SMOS observations and associated ancillary data. Daily products, in NetCDF format, are generated by the Finnish Meteorological Institute (FMI) and are available from 2010 onwards. The processing algorithm makes use of gridded Level 3 brightness temperatures provided by CATDS. The data is provided in the Equal-Area Scalable Earth Grid (EASE2-Grid), at 25 km x 25 km resolution.
