295GEOSTATS: Questions about universal and IRF-k kriging
- Apr 24, 1997Hello All,
I am a geostatistics novice seeking to apply an objective
statistical tool to some 3-D environmental sampling data. We
do artificial tracer release experiments to study horizontal and
vertical mixing processes in the ocean. We release our tracer
onto a constant density surface. We then sample the tracer's
spatial distribution on an irregularly spaced horizontal grid pattern
with approximately 25 data points in the vertical at each
sample location. The results are vertically integrated. We get
various "patchy" tracer distributions in the horizontal plane depending
on the mixing. I'm looking for a software package and reference
materials to explore both universal kriging and intrinsic random
function of order k processing. Our requirements are that I cannot
assume a stationary mean. I need to assume a gradient in the mean
within a window, and I would like to calculate the uncertainties in a
global mean not just uncertainties at a point.
Thanks in advance for any help you can provide.
