The Global Marine Information System has been developed to provide the Users community with an appropriate set of bio-physical information, of importance to conduct water quality assessment and resource monitoring in the coastal and marine waters. The bulk of environmental analysis in GMIS relies on Earth Observation data, and the provision of continuous, detailed and accurate information on relevant marine biophysical parameters as derived from optical, and infrared satellite sensors. The datasets are at global scale and available at a spacial resolution of 9 and 4km.
To access the datasets a http url is provided (http://gmis.jrc.ec.europa.eu/satellite/).
Each folder includes time series of datasets with IDENTIFIER CODED formed as follow:
DATASET IDENTIFIER CODE
Examples: ../satellite/9km/GMIS_A_CHLA_MM_YYYY
../satellite/4km/climatology/GMIS_A_CHLA_MM
../satellite/4km/anomalies/GMIS_A_ANO_CHLA_MM_YYYY
