| Infrared measurement at the sea surface, which constitutes an operational technology in remote-sensing, has become essential for the study of ocean dynamics. Nevertheless, observations are only usable when clouds do not mask infrared radiation coming from the ocean, a condition which rarely pertains in the Bay of Biscay as a whole. lt is consequently a matter of primary concern to have at one's disposai an effective method which permits the computation of mean SST fields from a chronological succession of incomplete images. In the case under consideration, "kriging" is the most widely practised method of performing geostatistical estimates. Before mapping isotherms, temperatures are estimated by interpolation on a regular gridnet. The process was applied... |
