Hi all,

I'm preparing a course in Geostatistics for ESRI Germany and
I never thought it was so difficult to find a simple dataset
to demonstrate some typical geostatistics-related topics.

I dream of data with the following properties:
a) area: in Germany
b) point data to calculate variography and do kriging
c) containing variables with different spatial behaviour,
e.g. Temperature, Precipitation and concentration of ozone.
d) free
e) it must make sense to apply Kriging & Co.

I was very happy if someone could help me to find
appropriate data or point me to something helpful...

Last I have to apologize fo my bad english.

I always consider as very useful, if not a necessary step, to built a fully
well known, because you monitor them, except maybe some part of random
noise or probability driven parameters (e.g. it could be the locations of
sampling). So, your statistical treatment(s) should be able to find what
you know being there !

Moreover, a priori sensitivity analysis is, from that point, and specially
if your test set of data is somehow "not too far" from the real sets of
data, just the next step, with systematics or Monte Carlo repeated
variations of the same procedure.

So do I !

There are also many data sets available on the web, if
