the following sensors is used for finding primary productivity
MODIS
SeaWiFS
MODIS
MERIS
OCM
primary productivity can measure with calculating chlorophyll-a concentration.
first need to collect water samples from ocean with GPS location when satellite overpass and to analysis chl-a concentration in laboratory . then to collect the satellite data for the corresponding date of water sample collection.
primary productivity can measure by generating correlation between sensor band values and insitu measured chlorophll-a values by using MATLAB. in near feature without field sample value can calculate the chl-a value in particular region after development of algorithm
