About
Landsat 9 Surface Temperature (Landsat 9) is part of Piksel's land surface temperature dataset series, which covers the thermal imagery archive from the US Geological Survey (USGS) Landsat satellite programme. This product is derived from the thermal infrared channel (Band 10) of the Thermal Infrared Sensor 2 (TIRS-2), an enhanced version of the Landsat 8 sensor, at 30-metre resolution. It is ready for monitoring urban heat islands, drought, vegetation stress and geothermal activity. Together with Landsat 8, the mission provides an 8-day revisit interval for high-resolution thermal monitoring across Indonesia.
