Re: 20011126: CONDUIT/ECMWF data for European Center for Geodynamics and Seismology



Hello Tonie, 

Your research sounds quite exciting, I hope we can help in some way.
I also worked with pressure fields, modelled vs. measured over Greenland
(atmos applications not geodetic, but pressure is pressure)

From your question,

2) what is the minimal grid spacing available?

I am assuming you are interested in the highest resolution possible.


There are some logistical and bureaucratic issues we need to investigate
before we proceed any further..i.e WMO resolution 40, and connectivity via
the internet to your institution to determine if this is a viable method
for data transfer.

Please see:

http://unidata.ucar.edu/data/data_usage.html

and

http://205.156.54.206/im/wmocovr.htm

regarding data usage.

To start, could you please provide me with the fully qualified domain name
of your machine that you hope to be ingesting the data, this way I can
analyze routings and possible latencies to your location.


 3) who should i talk to about getting the data and the software for

Please see:

and in particular:

http://unidata.ucar.edu/packages/ldm/index.html

for data access, and:


http://unidata.ucar.edu/data/exp.models.html


for more info regarding the high resolution (CONDUIT) model feed.

I hope this answers some of your questions, and hopefully we can help you
with data access for your research.

As an aside, you may also be interested in the SuomiNet project, deriving
water vapor profiles from the delay in GPS signals.
