SMOS-IC v2

Wigneron, Jean-Pierre, Li, Xiaojun · Recherche Data Gouv France · 2021

The SMOS-IC v2 product includes both a soil moisture (SM) and a L-band vegetation optical depth (L-VOD) data set which are currently at the basis of several studies evaluating the impact of climate and anthropogenic activities on aboveground carbon stocks. Since the release of the first version, the algorithm has been significantly changed in support to key applications. It has a spatial resolution is around 0.25° and a daily temporal resolution. All the details concerning the SMOS-IC v2 product can be found in: Jean-Pierre Wigneron, Xiaojun Li, Frédéric Frappart, Lei Fan, Amen Al-Yaari, Gabrielle De Lannoy, Xiangzhuo Liu, Mengjia Wang, Erwan Le Masson, Christophe Moisy, SMOS-IC data record of soil moisture and L-VOD: Historical development, applications and perspectives, Remote Sensing of Environment, Volume 254, 2021, 112238, ISSN 0034-4257, https://doi.org/10.1016/j.rse.2020.112238.

SMOS and hydrology

Kerr, Yann, Al Bitar, Ahmad, Leroux, Delphine et al. · Prodinra (INRA Bordeaux-Aquitaine) · 2015

SMOS, a L Band radiometer using aperture synthesis to achieve a good spatial resolution, was successfully launched on November 2, 2009. It was developed and made under the leadership of the European Space Agency (ESA) as an Earth Explorer Opportunity mission. It is a joint program with the Centre National d’Etudes Spatiales (CNES) in France and the Centro para el Desarrollo Teccnologico Industrial (CDTI) in Spain. SMOS carries a single payload, an L band 2D interferometric, radiometer in the 1400‐1427 MHz protected band. This wavelength penetrates well through the vegetation and the atmosphere is almost transparent enabling to infer both soil moisture and vegetation water content. SMOS achieves an unprecedented spatial resolution of 50 km at L‐band maximum (43 km on average) with multi angular‐dual polarized (or fully polarized) brightness temperatures over the globe and with a revisit time smaller than 3 days. SMOS has been now acquiring data for 5.5 years. The data quality exceeds what was expected, showing very good sensitivity and stability. The data is however impaired by man‐made emission in the protected band, leading to degraded measurements in several areas including parts of Europe and of China. However, many different international teams are now addressing data use in various fields including hydrology. We have now acquired data over a number of significant “extreme events” such as droughts and floods giving useful information of potential applications. We are now working on the coupling with other models and or disaggregation to address soil moisture distribution over watersheds. We are also concentrating efforts on water budget and regional impacts. From all those studies, it is now possible to express the “lessons learned” and derive a possible way forward. This paper thus gives an overview of the water cycle science goals of the SMOS mission, a description of its main elements, and a taste of the first results including performances at brightness temperature as well as at geophysical parameters level and how they are being put in good use for hydrological applications.

SMOS: The Payload

Kevin McMullan, Mike Brown, Manuel Martín‐Neira et al. · IEEE Transactions on Geoscience and Remote Sensing · 2008

The European Space Agency's Soil Moisture and Ocean Salinity satellite comprises a single payload instrument known as the Microwave Interferometric Radiometer with Aperture Synthesis (MIRAS) coupled to a PROTEUS platform. MIRAS synthesizes a large aperture from a reasonably sized 2-D array of passive microwave radiometers. By using interferometric techniques, the required coverage and spatial resolution can be achieved without the need for a large antenna. This paper describes the MIRAS instrument, its observation modes, the imaging geometry, and data products.

SMOS User Support Tools: SMOS-Box and Cal/Val Data Distribution

Quast, Ralf, Fomferra, Norman, Block, Thomas et al. · Figshare · 2014

The SMOS Toolbox for BEAM (SMOS-Box) consists of a collection of BEAM compliant software modules for decoding, visualization and basic inspection and analysis of operational products from ESA's Soil Moisture and Ocean Salinity (SMOS) mission. Since March 2010 the SMOS Data Distribution Facility of the CEOS Cal/Val Portal is delivering mission data to principle investigators coordinating the calibration and validation of the SMOS instrumentation.

SMOS 1km Soil Moisture

CSIC - Instituto de Ciencias del Mar (ICM) · DIGITAL.CSIC (Spanish National Research Council (CSIC)) · 2014

Soil moisture maps at 1 km spatial resolution over the Iberian Peninsula are obtained by optimally merging SMOS and MODIS data. Maps from the first two years of SMOS in orbit (historical dataset) are available. Furthermore, near real-time maps are daily generated at 4.30 am and 4.30 pm, corresponding to SMOS ascending and descending orbits
