Operated since the end of 2009, European Space Agency (ESA) Soil Moisture and Ocean Salinity (SMOS) satellite mission is first orbiting radiometer that collects regular global observations from space two Essential Climate Variables Global Observing System: Sea Surface (SSS) Moisture. The National Aeronautics Administration (NASA) Aquarius mission, with primary objective to provide SSS measurements operated mid-2011 mid-2015. NASA's Active-Passive (SMAP) primarily dedicated soil moisture...
Abstract. After more than 10 years in orbit, the Soil Moisture and Ocean Salinity (SMOS) European mission is still a unique, high-quality instrument for providing soil moisture over land sea surface salinity (SSS) oceans. At Barcelona Expert Center (BEC), new reprocessing of 9 (2011–2019) global SMOS SSS maps has been generated. This work presents algorithms used generation BEC product v2.0, as well an extensive quality assessment. Three fields are distributed: high-resolution level-3 (with...

The SMOS SSS presented this work are an improved version preliminary three-year dataset generated freely distributed by Barcelona Expert Center. In new version, a time-dependent bias correction has been applied mitigate seasonal that affected previous maps. An extensive database...
Changes in the Earth's water cycle can be estimated by analyzing sea surface salinity. This variable reflects balance between precipitation and evaporation over ocean, since upper layers of ocean are most sensitive to atmosphere-ocean interactions. In situ measurements lack spatial temporal synopticity typically acquired at few meters below surface. Satellite measurements, on contrary, synoptic, repetitive Here we show that satellite-derived salinity evidence an intensification (the freshest...
A new methodology using a combination of debiased non-Bayesian retrieval, DINEOF (Data Interpolating Empirical Orthogonal Functions) and multifractal fusion has been used to obtain Soil Moisture Ocean Salinity (SMOS) Sea Surface (SSS) fields over the North Atlantic Mediterranean Sea. The retrieval mitigates systematic errors produced by contamination land sea. In addition, this improves coverage means multiyear statistical filtering criteria. This allows obtaining SMOS SSS in However,...
Abstract. Measuring salinity from space is challenging since the sensitivity of brightness temperature (TB) to sea surface (SSS) low (about 0.5 K psu−1), while SSS range in open ocean narrow 5 psu, if river discharge areas are not considered). This translates into a high accuracy requirement radiometer 2–3 K). Moreover, TB at cold waters even lower (0.3 making retrieval more challenging. Due this limitation, ESA launched specific initiative 2019, Arctic+Salinity project (AO/1-9158/18/I-BG),...
The Geospatial Open Science Yielding Applications (GOYAS) project, under the umbrella of Horizon Europe project “OSCARS”, proposes a new approach for open science and data in remote-sensing, integrating FAIR principles (Findable, Accessible, Interoperable, Reusable) from initial design phase. GOYAS provides innovative and/or experimental Earth Observation (EO) practices to address diverse environmental challenges, delivering advanced geospatial products that are tailored...

In November 2009, the first L-band interferometric radiometer was launched as second Earth Explorer mission by European Space Agency (ESA), with primary goal of measuring soil moisture over land and sea surface salinity oceans. After more than 15 years, continues to provide excellent monitoring these two essential climate variables, offering unprecedented spatial temporal coverage resolutions.  Over data processing algorithms for retrieval have had evolve address significant...
Abstract Arctic sea ice is retreating. In the Beaufort Gyre (BG), liquid freshwater content (FWC) has increased by 40% in last two decades, with melting being one of contributors. Combining satellite observations and reanalysis outputs, we study meltwaters BG from 2011 to 2019. SMOS surface salinity (SSS) data were limited ice‐free period, outputs showed accuracy capturing postmelt freshening observed SSS. Applying criteria SSS 25 psu presence, identified meltwater lenses (MWLs) across...

Macroplastic pollution is a pervasive global environmental challenge, adversely affecting marine ecosystems, wildlife and human health. Understanding temporal variations crucial for identifying sources developing effective mitigation policies. However, in-situ data from beach surveys are often irregular, both spatially temporally, highly variable, complicating robust statistical conclusions. Here we employ Bayesian machine learning framework to investigate seasonal variations, identify...

Soil moisture and ocean salinity (SMOS) brightness temperature (TB) images calibrated visibilities are related by the so-called G-matrix. Due to incomplete sampling at some spatial frequencies, sharp transitions in TB scenes generate a Gibbs-like contamination ringing spread sidelobes. In current SMOS image reconstruction strategy, Blackman window is applied Fourier components of TBs diminish amplitude artifacts such as ripples, well other effects. this paper, novel algorithm focused on...
The error characterization of satellite observations is crucial for blending from multiple platforms into a unique dataset and assimilating them numerical weather prediction models. In the last years, triple collocation (TC) technique has been widely used to assess quality many geophysical variables acquired with different instruments at scales. This paper presents new formulation (Correlated Triple Collocation (CTC)) case three datasets that resolve similar spatial scales, two being...
Abstract. The hydrography of the Arctic Ocean has experienced profound changes over last 2 decades. sea ice extent declined by more than 10 % per decade, and its liquid freshwater content increased mainly due to glaciers melting. Further, new satellite retrievals surface salinity (SSS) in might contribute better characterizing cold regions. are intimately related such that an increase (decrease) one entails a decrease (increase) other. In this work, we evaluate Beaufort Gyre using...
Estimating sea surface salinity by European Space Agency's soil moisture and ocean (SMOS) mission in coastal regions is still a challenging task. The brightness temperature measured the SMOS interferometric radiometer biased at areas presence of land-sea contamination other variable sources error, mainly human-induced radio frequency interferences (RFI). In this paper, we will discuss on benefits for retrieving maps applying two correction techniques that enhance quality temperatures:...
Abstract The circulation in the Algerian Basin is characterized by presence of fresh‐core eddies that propagate along coast or at distances between 100 and 200 km from coast. Enhancements processing Soil Moisture Ocean Salinity (SMOS) data have allowed to produce, for first time, satellite sea surface salinity (SSS) maps Mediterranean Sea capture signature eddies. SMOS can be used track them long periods especially during winter. SSS are well correlated with situ measurements although former...

Abstract A proper description of ocean-atmosphere interactions is key for a correct understanding climate evolution. The interplay among the different variables acting over complex, often leading to correlations across long spatial distances (teleconnections). In some occasions, those teleconnections occur with quite significant temporal shifts that are fundamental underlying phenomena but which poorly captured by standard methods. Applying orthogonal decomposition such as Maximum Covariance...
