Today I received an email from USGS as a notice of planned changes to the processing and output options of Landsat Surface Reflectance (SR) Climate Data Records (CDR).
In the near future, users will be able to select from three output formats when submitting requests through the Earth Resources Observation and Science Center (EROS) Science Processing Architecture (ESPA) on demand interface (https://espa.cr.usgs.gov): HDF, GeoTIFF, or Binary. (CDR products requested from EarthExplorer will be delivered in GeoTIFF format only.)
The metadata will be delivered in an Extensible Markup Language (.XML) file, and the brightness temperature delivered as Band 6 in the top of atmosphere (TOA) reflectance product will be labeled in Kelvin instead of currently-noted Celsius.
Samples of the updated data are available for download from http://landsat.usgs.gov/
You will be notified again when the exact date of change-over to the updated products is determined. You may also check the news items posted on http://landsat.usgs.gov/CDR_
