HLS Known Issues
The list of HLS v2.0 Data Known Issues is maintained at HLS dataset landing pages: HLSL30 and HLSS30
Although HLS does not use the Landsat Collection-2 surface reflectance data directly, it uses an atmospheric correction code that is similar to the one used to produce the Landssat Collection-2 surface reflectance data. Therefore, the HLS surface reflectance shares the same problems present in Collection-2; see the heading “Surface Reflectance Issues” at landsat-collection-2-known-issues.
