A range of instruments in an agro-meteorological weather station are used to measure precipitation, temperature, wind and humidity. The measurements are normally made at 09.00 Greenwich Mean Time (GMT) each day. Most of the instruments are housed in a characteristic Stevenson’s Screen although there are usually other instruments on the designated ground or mounted on poles nearby (see Figure 2.1).
