New release of 1-km SMOS soil moisture over European and Mediterranean countries

Dear users,

First, we hope that you and your family are doing well in these challenging days.

We are pleased to announce the latest version (v5.0) of cloud-free BEC SMOS (Soil Moisture and Ocean Salinity) L4 soil moisture maps at 1 km covering Europe, the northern-most countries of Africa and western Russia. These maps are obtained from the synergy of:

  • SMOS L1C brightness temperature,
  • Terra MODIS (Moderate Resolution Imaging Spectroradiometer) NDVI (Normalized Difference Vegetation Index), and
  • ECMWF (European Center for Medium Weather Forecast) skin temperature.

The use of an adaptive window allows the downscaling algorithm to be applied over any non-frozen region of the world, regardless of the size of the region to be processed, and its spatial climatic variability. The BEC SMOS L3 soil moisture is used as a benchmark.

As a novelty, daily and 3-day L4 soil moisture maps are distributed in two different modes:

  • Near Real-Time maps provided with a latency of only 2 days,
  • Reprocessed maps provided with a latency of 3-4 weeks.

The reprocessed mode contains the series of all maps since June 2010.

Additionally, nomenclature and metadata of the latest version (v3.0) of global SMOS L3 soil moisture have been revised and updated.

A detailed explanation of both L3 and L4 algorithms and the resulting products is included in BEC SMOS Soil Moissture Products Description. Please, do not hesitate to contact us in case you have any question or comment at Your feedback is most welcome!

Enjoy the products!

New release of global SMOS soil moisture products at BEC

We are pleased to announce the new near real-time global SMOS L3 soil moisture products v003. These products have different averaging periods (and frequency rates): 1-day (daily) maps in both ISEA 4H9 and EASE-2 25 km, and 3-day (daily), 9-day (every 3 days), 1-month (monthly) and 1-year (yearly) maps in EASE-2 25 km. All of them have been generated using the latest version of SMOS L2 soil moisture processor (v650, which supersedes the previous L2 v620). The main improvements of v650 are related to algorithm updates, parameters configuration and auxiliary files changes.

New Research: Ocean Currents at BEC

Ocean currents are a key element for the understanding of many oceanic and climatic phenomena and their knowledge is crucial for navigation and operational applications. Following the official broadening of its scope, BEC has extended its research activity towards the diagnosis of ocean surface currents from satellite observations. This new research line, led by Dr. Jordi Isern-Fontanet, is being funded through the ComFuturo program ( granted by the FundaciĆ³n General del CSIC ( and through the GlobCurrent project ( funded by ESA.
