The August 13, 2018 Land Surface Temperature (LST) map shown below was created using Landsat Analysis Ready Data from USGS. The original Kelvin temperatures have been converted to Fahrenheit. When you move the cursor over the map, the temperature for each 30 square meter area will be displayed. Only LST values greater than (>) 99ºF are displayed, which reduces the file size from 477,852 polygons (81.7MB) to 157,312 polygons (26.2MB). The reduced file size takes about one minute to load into your web browser (depending on your network). Please be patient.

Note: The ambient air temperature in Minneapolis on 8/13/2018 was: Average (82 ºF); Max (92 ºF); Min (71 ºF). See the National Weather Service web site for more details.

The June 13, 2019 Land Surface Temperature (LST) map shown below was created using Landsat Analysis Ready Data from USGS. The original Kelvin temperatures have been converted to Fahrenheit.  LST temperatures below 100ºF have been group together and are colored light blue. LST temperatures from 100ºF to 120ºF have been grouped in 5ºF increments.  The LST temperatures from 120ºF to 137ºF have been grouped as polygon areas. This 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.

Note: The ambient air temperature in Minneapolis for the day of June 13, 2019 was: Average (62 ºF); Max (72 ºF); Min (52 ºF).  The time of this Landsat data collection was at 11:32am (for the center of the Landsat scene). The ambient air temperature at this time was ~ 72 ºF. See this  web site link for more details.
