The implementation follows conventional HDF usage (See HDF Users Guide): float value = scale_factor*(stored integer - add_offset) The unit of the derived floating point value is indicated in the 'units' local attribute which is also provided. identifier_product_doi String 10.5067/MODIS/MYD05_L2.061 identifier_product_doi_authority String http://dx.doi.org
