Re: THREDDS aggregation capability

Title: Re: THREDDS aggregation capability

Hi Ben:

THREDDS allows you to aggregate along any dimension, including a "new" one.  In your case, you would aggregate across time, and then do the normal OPeNDAP call for the one location, treating it as if it were one series.

You can see a lot of examples of this at:

http://oceanwatch.pfeg.noaa.gov:8081/thredds/catalog.html

All of the Items under the heading  "Aggregation Satellite Datasets" are aggregated in just this fashion . You can pick one and go to the html interface and see that you can select to get a time series at a point.  In fact, you can get a time series for a region.

HTH,
