La teledetección de la temperatura superficial del mar: una validación de los algoritmos en las aguas litorales del Mediterráneo español

Abstract

La temperatura superficial del mar es el auténtico motor del sistema climático. Los satélites meteorológicos han ampliado sensiblemente la cobertura espacial de esta variable fundamental. Sin embargo los datos llegados desde el espacio deben pasar una validación con datos in situ, la cual no carece de puntos débiles. Este artículo muestra un ensayo de validación de tres algoritmos existentes mediante datos procedentes de boyas marinas. La metodología consiste en comparar los datos de las boyas con los aportados por el satélite para las mismas coordenadas temporales y espaciales. Cabría concluir que los resultados observados son incluso mejor de lo esperado ya que el error medio máximo es inferior a 0,5 grados

The sea surface temperature (SST) is a key element in the climate system. Meteorological satellites extended the spatial coverage of this essential parameter. However, data from remote sensing systems must be validated with in situ data which, unfortunately, have their own weaknes. In the present work a validation test over three existent SST algorithms was carried out matching up the satellite data with buoy data. The approach consisted in a comparison of the two kind of data, a matchup of both data measured at the same or similar time. The result derived from this test was a good accuracy, better than expected, with a mean bias less than 0,5º C within the three algorithms
