Description |
|---|---|
| 9999 | Indicates pixels that are void of any retrieval due to inherent gaps between available L2A swaths. |
| -9999 | Indicates no retrieval due to bad brightness temperature data or screening by land surface classification, or unsuccessful retrieval due to retrieval values outside the physical range. |
Note: The dimension of each field is 586 rows x 1383 columns.
