Can you provide a URL for this service (the weather data). It is
hard to judge it without being able to see what the service does.
Thanks,

Hi,
We are currently handling this type of data using WFS with GML
observations or more explicitly GML application schemas (mainly for
the observation result) for the observation result. We are doing
this with weather data, radiation data, traffic data etc.
Cheers

Subject: weather station observation data in netCDF
Hello,
One of the issues confronting GALEON is the appropriate mechanism
for serving point data of the sort that is collected by weather
reporting stations. It could also be ocean buoys or river gaging
stations or air quality monitoring stations, but at Unidata we work
with a lot of real-time weather data so that's easiest to
experiment with. As part of the THREDDS Data Server NetCDF subset
service, there is now an option to use a browser interface to
request a subset of the real-time weather station observations on
our motherlode server:
http://motherlode.ucar.edu:8080/thredds/ncss/metars/dataset.html
In addtion to several options for specifying parameters, spatial
bounds, and a time subset, one can also request different output
formats:
-- "raw" is the form in which the METAR observations are transmitted
-- "xml" is a dialect of xml that's reasonably easy to decipher
-- "csv" is comma separated values
-- "netCDF" is a special netCDF encoding for this type of data
From the GALEON point of view, an interesting question is whether
it makes sense to try to serve this form of netCDF data via the WCS
interface. Or is it more appropriate to use the WFS or SOS
interface for these data collections?
It would also be interesting to know whether any of the GALEON
clients would be able to work with the netCDF-encoded data
delivered by such a server via any of the interfaces.
Your thoughts on these issues would be appreciated as well as
reports on any experiences you have in attempting to work with the
resulting netCDFs.
