Global Temperatures and Humidity

This site shows the different climate change parameters such as temperature (˚C), absolute humidity, relative humidity, dew point (Td) as well as actual and saturated vapor pressure within the states of America. We get our data from the NOAA (National Oceanic and Atmospheric Administration) site, which is provided in the form of dew point and temperature while the other variables are computed.  The relative humidity (RH) is expressed by the ratio of actual vapor pressure to saturated vapor pressure measured in percentage where actual vapor pressure (E) is given by:

The saturated vapor pressure (Es) is given by:
