Surface temperature and dewpoint are measured by an H1063 Hygrothermometer located outside and adjacent to the weather station. Relative humidity is derived from these data. The surface pressure is measured by a Vaisala model PA-11 digital barometer located in the weather station. A standard mercurial barometer and a recording microbarograph are also located in the weather station. The mercurial barometer is used to calibrate the digital barometer and the microbarograph.
Rainfall is measured by two rain gauges located outside the weather station.
The tipping bucket gauge has an automatic readout in the weather station, and the NWS standard 8 inch gauge is read manually by weather station personnel. A laser ceilometer at the weather station is used to measure cloud base heights up to 12,000 feet. Cloud heights and ceilings above 12,000 feet and horizontal visibility are visually estimated by weather station personnel.
