SMOS: A Satellite Mission to Measure Ocean Surface Salinity
The ESA’s SMOS (Soil Moisture and Ocean Salinity) Earth Explorer Opportunity Mission will be launched by 2005. Its baseline payload is a microwave L-band (21 cm, 1.4 GHz) 2D interferometric radiometer, Y shaped, with three arms 4.5 m long. This frequency allows the measurement of brightness temperature (Tb) under the best conditions to retrieve soil moisture and sea surface salinity (SSS). Unli...
متن کاملSea Surface Salinity Retrieval within the ESA Soil Moisture and Ocean Salinity (SMOS) Mission
The SMOS (Soil Moisture and Ocean Salinity) mission will provide from 2007 onwards global maps of soil moisture over land and sea surface salinity over ocean. The radiometry group of the Technical University of Catalonia (UPC) in Barcelona has been involved either in the definition of the SMOS single payload, MIRAS (Microwave Imaging Radiometer by Aperture Synthesis), or in the organization of ...
متن کاملPreliminary Results from Assimilating SMOS-mission Satellite Sea-Surface Salinity Fields in an NCEP Operational Ocean Forecast System
Over thirty occurrence of Ocean storm surges events over the Nigerian coastline were recorded between 1994-2012 and each with its devastating consequences resulting from the massive coastal flooding and erosion. It revealed that all Ocean storm surges apart from the surges of march 2002 were experienced in summer months of April to October, but more frequent in August. Some evidences in the Wes...
متن کاملSalinity from space unlocks satellite-based assessment of ocean acidification.
Approximately a quarter of the carbon dioxide (CO2) that we emit into the atmosphere is absorbed by the ocean. This oceanic uptake of CO2 leads to a change in marine carbonate chemistry resulting in a decrease of seawater pH and carbonate ion concentration, a process commonly called ‘Ocean Acidification’. Salinity data are key for assessing the marine carbonate system, and new space-based salin...
متن کاملAircraft and in Situ Salinity and Ocean Color Measurements: Bridging the Satellite Salinity Coastal Gap
New microwave salinity measuring satellites (SMOS, launched Nov, 2009 and AQUARIUS, to be launched spring 2010) have relatively large pixel size (35-80 km). This does affect their primary ocean missionglobal open ocean salinity measurements on a monthly time scale, to a limited extent. However, the large pixel size has a dramatic effect on measurements near the coast. It requires a large coasta...
