This data set contains the MODIS Aqua ocean colour satellite data from the period December 2002 to January 2004. The data are received as monthly composites, with a 4 km resolution, and are constrained to the region between 90E and 180E, and 10N to 60S. The data set is a level 3 product, where the chlorophyll accuracy has been assessed and the uncertainties in the product well established in a systematic and statistically robust way representing global rather than regional conditions. The data was sourced from http://modis.gsfc.nasa.gov/. The data are in hdf format, and consist of 96 files totaling approximately 850 MB. The Moderate Resolution Imaging Spectroradiometer (MODIS) administered by NASA Goddard Space Flight Center, is a 36-band spectroradiometer measuring visible and infrared radiation and obtaining data that are being used to derive products ranging from vegetation, land surface cover, and ocean chlorophyll fluorescence to cloud and aerosol properties, fire occurrence, snow cover on the land, and sea ice cover on the oceans, from a continuous global coverage every 1 to 2 days. The first MODIS instrument was launched on board the Terra satellite in December 1999.
