Landsat 4-5 TM Level-2
Coming later Landsat 4 and 5 carried the Thematic Mapper (TM). This collection is their Collection 2 Level-2 archive from USGS: surface reflectance from six bands and surface temperature from the thermal band, the longest run of 30 m surface reflectance in the Landsat record.
Schema v1 defines this collection, but lean v1 does not serve it yet. Requests for it answer 404 unknown-collection. GET /v1/collections will list it once it is live.

- Revisit 16 days per satellite, swath 185 km, WRS-2 path and row.
- Same scale and offset as the other Landsat Level-2 collections.
- The thermal band was acquired at 120 m and is delivered at 30 m.
- The time span is what schema v1 expects. The live collection document will publish the extent measured from the index.
- Phases refer to the build plan; see the Data overview.
