Summary: | This report presents measurements of surface meteorological data taken during three cruises of R/V Alliance to the Iceland-Faeroe frontal area during August 1991 (NORDIC'91), March 1992 (NORDIC'92a) and October 1992 (NORDIC'92b). Wind velocity and direction, as measured at three different locations on the ship, are compared with wind information retrieved from the scatterometer of the European Remote Sensing Satellite (ERS-1). As coincident in situ and satellite measurements are relatively rare, analysed winds from the UK Meteorological Office are also used for comparison. For the satellite data, different retrieval algorithms are applied. Beside the wind vector, its horizontal derivatives (e.g. horizontal divergence and curl) are also investigated.
