such as humidity, temperature, wind and precipitation.
1.1.3 In agricultural meteorology, macro and micro scale
observations are required. While macro-scale observations
provide information on the climatic background, most of the
agricultural planning and research activities require data on
the meso- or micro -climatic scales. Standard instrumentation
and standard exposure conditions in agricultural meteorology,
are important as far as comparability is concerned. However,
in research work, instruments and exposure conditions are not
always standard.
1.2 Meteorological Stations
1.2.1 Basic information on the physical environment can be obtained
from observations made at stations of the synoptic,
climatological and hydrological networks. Since these
networks maybe restricted in density and in kind of
observation, it is desirable that they be supplemented by
