Portland

The August 23, 2014 Land Surface Temperature (LST) map  for the Portland, Oregon area, which is shown below, was created using Landsat Analysis Ready Data from USGS. The original Kelvin temperatures have been converted to Fahrenheit.  LST temperatures below 80ºF have been group together and are dark blue. LST temperatures from 80ºF to 99ºF  have been group together in 10ºF increments and are colored light blue. LST temperatures from 100ºF to 130ºF have been grouped in 5ºF increments.  Cloud covered areas do not have any LST data shown in the map. Grouping of temperature areas has been done to reduce the file size, which improves web site performance. The reduced file size takes about one minute to load into your web browser (depending on your network). Please be patient.
