MODIS HDF File Specification MOD05_L2: MODIS Level 2 NIR and IR Total Precipitable Water
|
| Slope_and_Offset_Usage: |
The local SDS scale_factor and add_offset attributes are used for the
conversion of stored integer data to geophysical floating point numbers.
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.
