METEOROLOGICAL OBSERVATORY

The main purpose of meteorological observatory is to access the net availability of water and plan its optimum utilizations for irrigation. A model meteorological observatory is established in 1970 at Gotri campus, GERI. The main instruments installed in the observatory are as under.  

(1)               Rain Gauge

-                     Non recording

-                     Self Recording

(2)               Thermometers

-                     Maximum

-                     Minimum

-                     Dry Bulb

-                     Wet Bulb

(3)               Open Pan Evaporimeter

(4)               Anemometer

(5)               Wind Vane

(6)               Sunshine recorder

(7)               Barometer

Wind - Tunnel  

Accurate measurement of wind speed is very important in irrigation, shipping transport, aerodynamics etc. The instrument used for this purpose is three cup anemometer. Anemometer requires periodical calibration. For calibration purpose a wind tunnel is installed at Gotri, GERI. The tunnel having two test sections operates at maximum speed of 100 km/hr.
