HDF Predefined Local Attributes

Attribute Name Reserved Label(s) Definition Sample Value
Label long_name Long name of the SDS Sea ice by reflective characteristics
Unit units SI units of the data, if any none
Format format How the data should be viewed in Fortran format notation I3
Coordinate system coordsys Coordinate system to use for the data cartesian
Range valid_range Max and min values within a selected data range 0-254
Fill Value _FillValue Data used to fill gaps in the swath 255
Calibration scale_factor
