Processing MODIS satellite images for phytoplankton chlorophyll estimates
Satellite remote sensing is widely used for phytoplankton distribution evaluation. 
For mapping of chlorophyll, multivariate calibration was applied to validate MODIS 
satellite data against automated fluorescence records of chlorophyll. The 
measurements were carried out with a ferrybox system on board the ferry Finnpartner 
with regular route from Travemünde to Helsinki (Alg@line data). The satellite data 
was received in HDF-EOS format. Data for each band was extracted with HDFLook-MODIS 
software and further analyzed together with chlorophyll data with GRASS-GIS versions 
6.1 and 5. Statistical analysis was done with PLS and PCR analysis with the R 
statistical software.
Partial least square (PLS) regression analysis was used to validate chlorophyll 
records against 1 km resolution bands. Satellite data was received from Sodankylä 
Station, Finland and NASA GES Distributed Active Archive Center (DAAC) Data Pool 
through the Internet. The production of daily maps is automated with shell scripts 
and published in the Internet on
