Meteorological instrument systems contains sensors for atmospheric measurements. For example, a subset of the PBO GPS network uses a combination of Vaisala WTX510 and WTX520 units, which are low power devices with temperature, pressure, humidity, rain intensity, wind speed, and wind direction sensors. GPS and meteorological systems are good candidates for collocation because GPS and meteorological data are easily integrated into one data stream. Most of the meterological systems in the PBO and COCONet networks are configured for five-minute sample intervals and hourly downloads with the GPS data.
The meteorological data from these systems are used for augmenting weather forecasting as well as for hydrological studies. For example, the atmospheric pressure data at a site are used to separate the zenith total delay of precipitable water vapor (PWV) in the troposphere into the hydrostatic and wet components of PWV and the other met observables are compared with model results after PWV and other processing.
