General Overview

Surface and Tower Meteorological Instrumentation at NSA (METTWR) use mainly conventional in situ sensors to measure wind speed, wind direction, air temperature, dew point, and humidity mounted on either a 10-m or a 40-m tower. It also obtains barometric pressure, visibility, and precipitation data from sensors at or near the base of the towers. In addition, Chilled Mirror Hygrometers are located on the towers for comparison purposes.
