MOD29P1N and MYD29P1N Local Sea Ice Attributes, Version 5
Local attributes describe the data and provide summary information about the results of the sea ice algorithm. Two types of local attributes are reported: Hierarchical Data Format (HDF) predefined and custom local attributes.
HDF Predefined Local Attributes
| Attribute Name | Reserved Label(s) | Definition | Sample Value |
| Label | long_name | Long name of the Scientific Data Set (SDS). | Ice surface temperature for daily tile |
| Unit | units | International System of Units (SI) of the data. This attribute may or may not be used. | degree_Kelvin |
| Format | format | How the data should be viewed in Fortran format notation | F4.1 |
| Coordinate system | coordsys | Coordinate system to use for the data | cartesian |
| Range | valid_range | Maximum and minimum values within a selected data range | 21000,31320 |
| Fill Value | _FillValue | Data used to fill gaps in the swath | 7 |
| Calibration | scale_factor |
Value by which each data element is to be multiplied¹ | 0.01 |
| scale_factor_err | Error induced by scaling¹ | 0.0 | |
| add_offset | Value to add to each array element¹ | 0.0 | |
| add_offset_err | Error induced by offset¹ | 0.0 | |
| calibrated_nt | HDF data types of the calibrated data¹ | 23 |
¹ These values are only used for Ice Surface Temperature (IST).
