Landsat Collections: Providing a Stable Environmental Record for Time Series Analysis
Why does my Landsat Collection 2 Surface Temperature product have missing data?
Landsat Collection 2 Surface Temperature products are generated from several input data sources and atmospheric profiles. This includes NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Dataset (GED).
The ASTER GED dataset is created from all clear-sky pixels of ASTER scenes acquired from 2000 through 2008. While this dataset has a global spatial extent, there are areas that are missing the mean emissivity information due to persistent cloud contamination in the ASTER measurements. When mean emissivity information is missing, the Surface Temperature product will contain areas of missing data.

How do I rescale Landsat Level-1 digital numbers to reflectance, radiance, and brightness temperature?
Landsat Level-1 data can be rescaled to the top of atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the metadata file (MTL.txt) that is delivered with the Landsat Level-1 product. The MTL file also contains the thermal constants needed to convert thermal band data to TOA brightness temperature (BT). Formulas for these conversions are at Using the...
Where can I get current sea-surface temperature data?
The USGS has studied sea-surface temperature in many areas around the globe; you can find publications from these studies in the USGS Publications Warehouse and by searching on the Internet. World maps and data are available from other agencies, particularly at the NOAA's Sea Surface Temperature , and at the JPL Physical Oceanography Distributed Active Archive Center. For specific data covering...
What updates were made in Landsat Collection 2?
Landsat Collection 2 marks the second major reprocessing event of the USGS Landsat archive. Continuing the tiered collection management structure implemented in Landsat Collection 1, Landsat Collection 2 introduces several advancements in data processing, algorithm development, as well as data access and distribution capabilities, including: Improved per-pixel geodetic accuracy by incorporating...
How do Landsat Collection 2 Level-2 products compare with products from Collection 1?
Landsat Collection 2 Level-2 Surface Reflectance and Surface Temperature science products are scene-based, produced within the standard processing system, and available to download directly from EarthExplorer. Collection 2 Level-2 products are available for Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI/TIRS data acquired from 1982 to present. Landsat MSS 1-5 data are not currently available...
Why are the fill values and scaling factors of Landsat Collection 2 Level-2 products different from those products in Collection 1?
The fill values and scale factors of Landsat Collection 2 Level-2 products were updated to be consistent with that of Landsat Collection 2 Level-1 data, while using the unsigned integer data type more efficiently. As shown in the table below, the fill value of the Surface Reflectance and Surface Temperature bands were changed from “-9999” in Collection 1, to “0” in Collection 2 to be consistent...
How do I search and download Landsat Collection 2 data products?
Landsat Collection 2 Level-1 and Level-2 products can be searched using EarthExplorer, the primary portal used to search all data held in the USGS EROS archives. Landsat Collection 2 products are processed and stored in the USGS Cloud Hosting Solution (CHS) environment; downloads are managed through EarthExplorer. The USGS Landsat no-cost open data policy remains intact since its inception in 2008...
What are Landsat Collection 2 Full Resolution Browse Images?
Similar to Landsat Collection 1 LandsatLook Images, the Landsat Collection 2 Full Resolution Browse Images are .JPG and .TIF images with geographic referencing that are compressed and stretched to create an image optimized for image selection and visual interpretation. They are derived from Landsat Collection 2 Level-1 data and are available to download from EarthExplorer. Learn more: Landsat Full...

Landsat Collections — What are Tiers?
This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors.
