mettwr > Surface and Tower Meteorological Instrumentation at NSAInstrument Type(s) > Baseline

The surface and tower meteorological instrumentation uses mainly conventional in situ sensors mounted on a tower to measure wind speed, wind direction, air temperature, dew point, and humidity. It also obtains barometric pressure, visibility, and precipitation data from sensors at or near the base of the tower. In addition, a chilled mirror hygrometer is used for comparison purposes.
