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 operational SSS products: version 2.00

L4 SSS product. The new binned debiased SSS product is fused with OSTIA SST daily, The animation corresponds to the full year 2015.

L4 SSS product. To product it, the new OA debiased SSS product is fused with OSTIA SST daily. The animation corresponds to a period from February to July 2015.


In a continuous effort to bring the higher quality products to our users, BEC is happy to announce that a new version of BEC SSS products (v2.00) has been put into operations.

In the new operational version, Land Sea Contamination has been mitigated by means of the empirical salinity debiasing method proposed in [Olmedo et al., 2016]. This leads to higher quality products that can be used for many different purposes. This new dataset is available at BEC products – Available variables – Sea Surface Salinity – Operational V2.0 section or by clicking here.
