Feb 6, 2014 • [Source: USGS] Landsat Surface Reflectance Climate Data Records (CDRs) are high level Landsat data products that support land surface change studies. Climate Data Records, as defined by the National Research Council, are a time series of measurements with sufficient length, consistency, and continuity to identify climate variability and change. The U.S. Geological Survey (USGS) is using the valuable 40-year Landsat archive to create CDRs that can be used to document changes to Earth’s terrestrial environment.
Landsat Surface Reflectance CDRs are generated using Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) software, which applies Moderate Resolution Imaging Spectroradiometer (MODIS) atmospheric correction routines to Landsat Level-1 scenes.
The following products are available as options when requests for surface reflectance processing are made through the on-demand USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) system (https://espa.cr.usgs.gov/):
● Source Products (Landsat Level-1 Product or Metadata, or both)
● Top-of-Atmosphere Reflectance [Hierarchical Data Format for Earth Observing System (HDF-EOS) data format]
● Surface Reflectance (SR) (HDF-EOS data format)
● Band 6 Brightness Temperature (HDF-EOS data format)
