The availability of cloud-free Landsat ETM+ data over the conterminous United States and globally

  title={The availability of cloud-free Landsat ETM+ data over the conterminous United States and globally},
  author={Junchang Ju and David P. Roy},
The U.S. Landsat satellite series provide the longest dedicated land remote sensing data record with a balance between requirements for localized high spatial resolution studies and global monitoring. As with any other optical wavelength satellite sensor, cloud contamination greatly compromises image usability for land surface studies. Additionally, selective scene acquisition due to payload, ground station and mission cost constraints further reduces Landsat image availability. Since the 1999… CONTINUE READING
