[ES] La misión SMOS (Soil Moisture and Ocean Salinity, Humedad del Suelo y Salinidad de los Océanos) de la Agencia Espacial Europea tiene el objetivo de obtener mapas globales de ambas variables desde el espacio para estudios climáticos y de gran escala. Usa un radiómetro interferométrico en la banda L de microondas (MIRAS) para medir la temperatura de brillo (Tb) emitida por la superficie terrestre, y a partir de ella calcula las dos variables geofísicas. La salinidad se obtiene mediante un proceso complejo de los datos radiométricos que requiere información sobre otros parámetros ambientales como temperatura y rugosidad de la superficie del mar
[EN] The European Space Agency SMOS (Soil Moisture and Ocean Salinity) mission aims at obtaining global maps of both variables from space for large scale and climatic studies. It uses an L-band microwave interferometric radiometer with aperture synthesis (MIRAS) to measure the brightness temperature (Tb) emitted by the Earth’s surface and then computes from it the two geophysical parameters. The retrieval of salinity is a complex process that requires the knowledge of other environmental information, as sea surface temperature and roughness, and an accurate processing of the radiometer measurements
La participación española en SMOS ha sido posible gracias a la financiación del Centro para el Desarrollo Tecnológico Industrial (CDTI) y el Programa Nacional del Espacio. Este artículo es una contribución al proyecto ESP2004-00671
