hi philippe--- the international water management institute has an
online query tool that you might find helpful
(http://www.iwmi.cgiar.org/WAtlas/AtlasQuery.htm). my grad student,
eugenia lo, discovered it, and we have used it to obtain meteorological
data for sites from which we have collected crataegus spp.

as a result of this use i can say that while it is convenient, it
provides *interpolated* data that may be inaccurate in detail, while not
in overall pattern. iwmi also provides software (and data) for download,
but i have found the accompanying explanatory text to be insufficient to
my needs as a potential user.
another tool that i found out about from a graduate student in mexico is
FloraMap (http://www.floramap-ciat.org/). it also is a package of data
and software, in this case available for a modest charge on a cd. altho
a manual is provided, i found that using it required more effort than i
could spare in the absence of another, more experienced user to call
upon for help. the manual for floramap is much more comprehensive than
the documentation accompanying the iwmi product, and provides many more
hints about the limitations of the data and the caution with which their
analyses should be interpreted.
