Local attributes describe the data and provide summary data on the results of the snow cover algorithm. Two types of local attributes are reported: HDF predefined, and custom local attributes.
| Attribute Name | Reserved Label(s) | Definition | Sample Value |
| Label | long_name | Long name of the SDS | Snow_covered_land |
| 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 | latitude, longitude |
| 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 scale_factor_err add_offset add_offset_err calibrated_nt |
Not used | Not used |
| Attribute Name | Definition | Sample Value |
| Cell_area | Nominal cell area | 0.21 |
| Max_snow_area | Estimated area covered by snow | 445772.2 |
| Cloud_cover_area_pct | Percentage of cloud in the tile | 5 |
| Key | Key to interpretation of coded integers | 200 = snow 100 = lake ice 50 = cloud 39 = ocean 37 = inland water 25 = land 11 = night 4 = erroneous data 3 = beyond 45 degree scan angle 1 = missing data 0 = no decision |
