Please consider using the USGS Level-2 Surface Temperature product, rather than using this site to calculate surface temperature.
The Surface Temperature product is available for the entire Landsat archive.
For more information, see the USGS Collection-2 Level-2 product description.
Please do not submit queries more often than every 2 minutes. Repeated rapid querying of the site causes problems for all users. Thanks for your cooperation.
Please email me if you have issues with this.
