This collection of resources, provided by the National Weather Service Forecast Office for the El Paso area, allows users to be their own meteorologists. For example, armed with data such as current temperature, humidity, and windspeed, users may calculate the heat index or wind chill. Using the resources on this page, and providing basic meteorological data such as temperature, air pressure, and dew point, users can calculate such things as the vapor pressure, maxing ratio, or density altitude. This site also provides unit conversion calculators, allowing users to convert temperatures, air pressures, and wind speeds into various units. For some of the conversions, this site presumes its users to have an understanding of meteorological terms and to be able to read basic meteorological instruments.
