smos soil moisture resolution

The Soil Moisture Ocean Salinity (SMOS) mission, launched in November 2009, incorporates an interferometric radiometer at L-band (1.4 GHz) and provides SM with a resolution of 30–55 km and a sensing depth of 3–5 cm (Kerr et al., 2001, Kerr et al., 2010). The synergy of SMOS and SEVIRI provides a pathway to enhance water cycle EO capabilities taking full advantage of the new observational records of SSM and operational geostationary information. The pixels are consolidated in a pole-to-pole product file (50 minutes of sensing time), with a maximum size of about 350MB per half orbit (29 half orbits per day).
Instantaneous and daytime averaged SSM agree well with in situ measurements. In addition, the US Department of Agriculture Foreign Agricultural Service has started to incorporate data into their forecasting system to help predict how the health of plants will change and, therefore, how productive they will be. SSM instantaneous estimates at the time of SMOS overpass and daytime-averaged SSM estimates have been obtained and evaluated separately against collocated in-situ measurements acquired from a total of 40 stations belonging to the REMEDHUS, VAS and SMOSMANIA permanent soil moisture measurement networks. The SSM retrieval technique allows for: i) enhancing the spatial resolution of SMOS SSM product estimates to 3 km spatial resolution, and, ii) providing a temporal average daytime SM product from the instantaneous fine-scale SSM estimates acquired every 15 min; the latter is allowing higher coverage in presence of clouds and representativeness (up to 96 estimates per day) in comparison to the instantaneous estimate at the time of satellite overpass.

Earth Observation (EO) technology is today at a maturity level that allows deriving operational estimates of Surface Soil Moisture (SSM) from a variety of sensors; yet, such products are provided at present at a coarse spatial and/or temporal resolution, which restricts their use in local or regional scale studies and practical applications. The proposed technique has been implemented to SMOS and MSG (Meteosat Second Generation) SEVIRI (Spinning Enhanced Visible and Infrared Imager) observations acquired over the Iberian Peninsula and Southern France during year 2011. SMOS is now helping to fill this gap thereby improving our knowledge of the global water cycle. In addition, the mission is expected to provide useful data for cryosphere studies.
For example, the mission’s near-realtime observations are now being integrated into the European Centre for Medium-Range Weather Forecasts’ system, helping to improve air temperature and humidity forecasts near the surface.

Going way beyond its original scientific brief of delivering critical information to understand Earth’s water cycle, SMOS continues to … For further detailed information on the SMOS instrument please see here. In addition, the mission is expected to provide useful data for cryosphere studies.

The SMOS (Soil Moisture Ocean Salinity), mission is a direct response to the current lack of global observations of soil moisture and ocean salinity which is needed to further our knowledge of the water cycle, and to contribute to better weather and extreme-event forecasting and seasonal-climate forecasting. SMOS measurement goals for soil moisture and ocean salinity are provided here. The principal objective of the SMOS mission is to provide maps of soil moisture and ocean salinity of specified accuracy, sensitivity, spatial resolution, spatial coverage and temporal coverage. © 2016 Elsevier Inc.
