MAWS

The MAWS measures temperature, humidity, and pressure at near ground level. It also measures wind speed and wind direction at 10 meters. The MAWS is critical for radiosonde launches as it provides important baseline information for the preflight checks of the radiosondes. It also contributes to the greater ARM facilities by adding another set of surface meteorological instrumentation.

Data are collected daily in one-minute averages of 10-second samples, and a file containing each day’s data is created by Vaisala MetCast Observation Console software.
