The basic meteorological data are measured and recorded simultaneously by a multi-sensor instrument the Vaisala WXT520 multiparameter weather transmitter. The Meteorological parameters measured are: - air temperature unit[deg C], - Atmospheric pressure[hPa], - Relative humidity[%], - Wind speed[m/s] and direction[deg], - Precipitation[mm].

The Pheriche Station is equipped with a rain gauge which is a sensor to measure rain quantity. At the AWS Pheriche station the DQA035 Lsi-Lastem rain gauge is mounted on a 1,5 m pole. This model of Rain gauge has a 1.000 cmq collector area.

An Automatic Weather Station (AWS ) has been installed over the past 10 years in Pheriche (4,260 m a.s.l.) nearby the Pyramid Laboratory-Observatory (5,050 m a.s.l.). The Automatic Weather Station (AWS ) takes hourly measurements of seven standard parameters: temperature, relative humidity, atmospheric pressure, wind speed and direction, global radiation, total precipitation.

At the AWS Pheriche station the CX115P Lsi-Lastem barometer is connected with measurement system (recorder, data logger) that accepts analog signals. The barometer functions according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance. The CX115P model mounts a special thermal compensation system that significantly reduces drift. The sensor take hourly measurements of atmospheric pressure.
