Please Take the CONDUIT User Survey

14 March 2012

CONDUIT The Cooperative Opportunity for NCEP Data Using IDD Technology (CONDUIT) uses Unidata's Local Data Manager (LDM) and Internet Data Distribution (IDD) technologies to make high-resolution model data sets available to the U.S. Weather Research Program (USWRP) and university communities. These NCEP model data consist of a substantial set of NCEP and NWS model data not currently available on NOAAPort.

NCEP and Unidata are in the process of evaluating the contents of the CONDUIT data feed. We would like your help in determining which of the model output currently included in the feed are in use, which are candidates for removal from the feed, and which new model runs (if any) should be added to the feed.

The survey should take fewer than five minutes of your time. Please give us your feedback!
