Description The similarity between the diurnal patterns of monthly mean dew-point temperatures for April in Nlamey, West Africa and Patancheru, India is striking The small diurnal varlatxon in vapour pressure relative to the vapour pressure defictt is similar in both locations.
Although the error m estimating dally mean vapour pressure deficit from two spot readings of humidity is small xn the example given by Culf et al (1994), in India this is
not always so for lndlvmal days (as opposed to monthly means) To illustrate this I have compared dally mean vapour pressures from the automatic weather statxon at the ICRISAT Center (readmgs every 5 mln) with means from spot readings at 07 15 and 14 15 h The difference between the two, expressed as a percentage of the mean dally vapour pressure deficit, was computed between May 1981 and October 1985 for
each day in the analysis of Butler (1992) This gave the distribution of the error in calculating mean dally vapour pressure deficit from two spot readings of humidity
(Fig 1) Overall, the mean error for the whole period was close to zero, but on individual days the error commonly exceeded 10% ...
