March 23, 2017 - Landsat 7 ETM+ Surface Reflectance Interruption

On March 12, 2017, the Ozone Monitoring Instrument (OMI) onboard the NASA Aura satellite entered survival mode.  Successful recovery efforts allowed data to resume on March 18, 2017.  Since OMI ozone auxiliary data are required for the processing of Landsat 4-5 TM and Landsat 7 ETM+ Surface Reflectance from ESPA, no L7 ETM+ scenes acquired from March 12  to March 17, 2017 can be successfully processed to Surface Reflectance.  We apologize for this inconvenience.

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
