METEOROLOGICAL OBSERVATORIES


 

 

A TYPICAL METEOROLOGICAL OBSERVATION STATION

An observing station should be located on a flat area free from obstacles e.g. buildings, trees etc. The station should have a compound of not less than 5 hectares so that it is able to house an office block, an observatory and staff houses.

The instruments that are normally installed in the Observatory are shown in the table of METEOROLOGICAL INSTRUMENTS To operate a meteorological station, 8 Meteorological Assistants are required.

The observations are normally made at 0000Z, 0300Z, 0600Z, 0900Z, 1200Z, 1500Z, 1800Z and 2100Z. The observed parameters are then relayed to the National Meteorological Centre immediately by use of Telephones, Fax, Radio telephone and Teleprinters from the four Data Collection Centres in the country

METEOROLOGICAL INSTRUMENTS 

The department runs a Meteorological Instruments Workshop which has a capability of manufacturing basic meteorological instruments such as Standard Rain gauges, Evaporation Pans, Stephenson screens and basic mechanical spare parts for repair and maintenance of instruments.

The Workshop has the capability of preparing materials for meteorological observatory such as sunshine pillars, optical pilot balloon pillars and fencing pillars for an observatory.

Calibration

The department has a well equipped Instrument Calibration Unit. The function of this unit is to repair and calibrate instruments namely:- Rain gauge, Thermohygrographs, Barometers etc. The unit also maintains and calibrates instruments from other Organizations including instruments from neighbouring countries within the African Region.
