GIS TOOL: TEMPERATURE EXTRACTION BY COORDINATE

Gridded objective analysis of current global dewpoint temperature at 2 m above ground level. Dewpoint temperature is a measure of atmospheric moisture. It is the temperature to which air must be cooled to reach saturation (assuming air pressure and moisture content are constant), and fog and/or water drops on exposed surfaces will likely form. A higher dew point indicates more moisture present in the air. The dewpoint temperature contributes to relative humidity and human comfort (e.g. heat index). Dewpoint temperature in this service is provided in degrees Celsius and analyzed on a 7km grid. WDT Technology
