CountrySpain  Spain
Time periodFrom 5 December 1982 to 26 October 1991

Temperature of the water column


The TSM and CCP data present in this collection have been taken by AVHRR sensors (aboard satellites of the NOAA series) and CZCS (on Nimbus 7). Their selection has been carried out following criteria by the observation of quicklooks available at the satellite data receiving station of Maspalomas (Gran Canaria). Later the data were processed to the parameters quoted herein after eliminating the effects of atmospheric extinction and geometric distortion of the original data. The spatial resolution of the data is as follows: 1.1 km for TSM data and 0.8 km for CCP data. The temporal resolution of the data is irregular due to the intermittent nature of the data. In total 25 CCP pictures are available (2 in 1982, 16 in 1983, 3 in 1984, 4 in 1985) and 186 TSM pictures (20 in 1987, 29 in 1988, 38 in 1989, 54 in 1990, 45 in 1991). The TSM and CCP satellite pictures are in ERDAS format. ERDAS is a software designed for the treatment of digital images which has a file of subroutines which allows for the creation of special application programs, such as those used for the processing of this collection of data.
