WebCertain instruments are located at every Mesonet site to measure the standard-primary variables. These variables are as follows: air temperature measured at 1.5 meters above the ground, relative humidity measured at 1.5 meters above the ground, wind speed and direction measured at 10 meters above the ground, barometric pressure, rainfall, In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore, total air temperature is higher than the static (or ambient) air temperature.
