Landsat Collection 2 Surface Temperature

Landsat surface temperature measures the Earth’s surface temperature in Kelvin and is an important geophysical parameter in global energy balance studies and hydrologic modeling. Surface temperature data are also useful for monitoring crop and vegetation health, and extreme heat events such as natural disasters (e.g., volcanic eruptions, wildfires), and urban heat island effects.

Return to Landsat Science Products Overview

The surface temperature product is generated from the Landsat Collection 2 Level-1 thermal infrared bands, Top of Atmosphere (TOA) reflectance, TOA brightness temperature, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Database (GED) data, ASTER Normalized Difference Vegetation Index (NDVI) data, and atmospheric profiles of geopotential height, specific humidity, and air temperature extracted from Goddard Earth Observing System (GEOS) Model Version 5 Forward Processing Instrument Teams (FP-IT) (for acquisitions from 2000 to present) or Modern Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) (for acquisitions from 1982 to 1999).

Product Availability

Global scene-based surface temperature data are available globally for the following instruments:

  • Landsat 8 Operational Land Imager (OLI): April 2013 to present
  • Landsat 7 Enhanced Thematic Mapper Plus (ETM+): July 1999 to present
  • Landsat 5 Thematic Mapper (TM): March 1984 to May 2012
  • Landsat 4 Thematic Mapper (TM): July 1982 to December 1993

Atmospheric Auxiliary Data

Collection 2 Surface Temperature products require atmospheric auxiliary data input from external USGS data sources. USGS retrieves data from the data source and extracts parameters specific to Landsat Collection 2 Level-2 processing. These subset data sets are available for download for users who wish to perform Level-2 processing. It is not necessary for users to download atmospheric auxiliary data sources to use Collection 2 Level-2 products.

Visit the Landsat Collection 2 Atmospheric Auxiliary web page for additional information.

 

Constraints and Caveats

Most Collection 2 Landsat 4-8 day-lit (descending acquisitions) surface reflectance scenes can be processed to a surface temperature product, but please note the following;

  • The Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Emissivity Dataset (ASTER GED) provided by the Land Processes Distributed Active Archive Center (LP DAAC) is used in the generation of a Landsat surface temperature product. Where ASTER GED data is missing, there will be missing data in the Landsat ST product.  Note : To investigate the availability of any given pixel, the “ASTER Global Emissivity Dataset 100 meter HDF5 V003” data can be attained from https://www.doi.org/10.5067/Community/ASTER_GED/AG100.003
  • Goddard Earth Observing System Model, Version 5 (GEOS-5) Forward Process for Instrument Teams (FP-IT) data are used to generate surface temperature products from 2000 to present. NASA’s Modern-Era Retrospective Analysis for Research and Application (MERRA-2) data are used to generate surface temperature products from 1982 to 1999.
  • Atmospheric auxiliary data used for processing a Collection 2 Level-1 product into surface temperature are described in the Landsat Atmospheric Auxiliary Data Format Control Book.
  • Data products must contain both optical and thermal data (e.g., LC08 products for Landsat 8) to be successfully processed to surface temperature, as ASTER NDVI is required to temporally adjust the ASTER GED product to the target Landsat scene. Therefore, night time acquisitions cannot be processed to surface temperature.
  • A known error exists in the surface temperature retrievals relative to clouds and possibly cloud shadows. The characterization of these issues has been documented by Cook et al., (2014).
  • For Landsat 7 ETM+ products, Band 6 TOA BT and ST data are generated from ETM+ Band 6 High (6H) and 6 Low (6L) merged together. The merged band contains unsaturated pixels from Band 6H. If Band 6H pixels have a BT outside of the 6H dynamic range (240 to 322 Kelvin) then 6L band pixels are used. Pixels that are saturated in Band 6L remain saturated in the merged Band 6 product. The merged thermal radiance is then used in the creation of the TOA BT and ST data.

Data Access

Landsat Collection 2 Level-2 data will be available from EarthExplorer and LandsatLook. The USGS Landsat no-cost open data policy remains intact since its inception in 2008.

New for Collection 2 is the ability for users to select individual Landsat bands for download. The EarthExplorer Bulk Download option also supports individual band selection and will add all files to the Bulk Order for download using the Bulk Download Application (BDA).

Visit the Landsat Data Access webpage for additional data access and download options.
