- Occasionally, Landsat data cannot be processed to Surface Reflectance due to missing auxiliary data.
For the past several months, I have been hearing from users of ENVI about a new set of provisional Landsat products being provided by the USGS.These products, known as Surface Reflectance High Level Data Products, are generated by specialized software that was originally developed by NASA.The software applies radiometric calibration and atmospheric correction algorithms to Level-1 Landsat …
Landsat 8 sr_aerosol Values ..... 16 Table 6-8.
A comparison here shows that Landsat 8 and Sentinel-2 imagery on the same date only 15 minutes apart both converted to surface reflectance with the Frequency 50 - .008 method, have similar values to each other and USGS Landsat 8 Algorithm Surface Reflectance.
I downloaded some Landsat 8 OLI/TIRS C1 Level-1 images from EarthExplorer.

The SR product delivers modeled surface reflectance from Landsat TM/ETM+/OLI data using physical rather than empirical models.
map algorithm, named LaSRC (Land Surface Reflectance Code), developed by Eric Vermote (NASA GSFC).
Ask Question Asked 1 year, 2 months ago. When creating or editing a layer select a processing level (TOA or Surface) if it applies to the product. USGS Landsat 5 Surface Reflectance Tier 1 This dataset is the atmospherically corrected surface reflectance from the Landsat 5 ETM sensor. I was hoping to get reflectance data out of the blue, green and red band; however, when I opened those images in ArcMap, the scale does not seem to be reflectance, given that is not in the … Initially, we are offering surface reflectance versions of all Landsat 8 and Sentinel-2 imagery that we ingest. The Land Surface Reflectance Code (LaSRC) Product Guide describes the LaSRC algorithm and the Landsat 8 Surface Reflectance data products created from it. The Land Surface Reflectance Code (LaSRC) Product Guide describes the LaSRC algorithm and the Landsat 8 Surface Reflectance data products created from it.

a. Prototype Landsat 8 OLI surface reflectance product derived from a 185 km × 180 km L1T image acquired over Chesapeake Bay, MD, USA, April 21 2013. Information about Surface Reflectance processing of Landsat 8 data can be found in the . The product described here, the Landsat 8 Surface Reflectance Code (LaSRC) is distinctly different from the algorithm used by USGS to process Landsat 4–5 Thematic
