Hi Andrey

I am working with MODIS data

There are l2 and l3 data sets in the 'images' directory of 
the MODIS Ocean Color tutorial 
http://jeager.gsfc.nasa.gov/modis_workshop_unh/

I suggest that we use these as our 'standard' MODIS test files

Note I hope to eventually be able to duplicate the functionality of the 
matlab and IDL code in this tutorial with GDAL and Python

Cheers

Norman
