Mapping description
The table below details where and how each variable was retrieved from the input product.
| field name | mapping description | |
|---|---|---|
| scan_subindex | description | the scanline and ground pixel dimensions are collapsed into a single temporal dimension; the index of the pixel within the scanline is computed as the index on this temporal dimension modulo the number of scanlines |
| datetime | path | /BAND6_RADIANCE/STANDARD_MODE/OBSERVATIONS/time, /BAND6_RADIANCE/STANDARD_MODE/OBSERVATIONS/delta_time[] |
| description | time converted from milliseconds since a reference time (given as seconds since 2010-01-01) to seconds since 2010-01-01 (using 86400 seconds per day); the time associated with a scanline is repeated for each pixel in the scanline | |
| orbit_index | path | /@orbit |
