WashDC TIR Map



The 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 413,978 polygons (65.9MB) to 106,089 polygons (17MB). 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 Washington D.C. on 7/8/2018 was: Average (75 ºF); Max (85 ºF); Min (64 ºF). See this  web site link for more details.

The July 29, 2020 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 130ºF have been grouped in 5ºF increments.  The LST temperatures from 130ºF to 150ºF 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 Washington D.C.  for the day of July 29, 2020 was: Average (84 ºF); Max (92 ºF); Min (75 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  about 89 ºF. See this  web site link for more details.

The August 17, 2015 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 130ºF have been grouped in 5ºF increments.  The LST temperatures from 130ºF to 136ºF have been grouped as as single polygon area. 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 Washington D.C.  for the day of August 17, 2015 was: Average (82 ºF); Max (95 ºF); Min (72 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  about 87 ºF. See this  web site link for more details.
