We’ve been working with Synoptic for a while now to feed Tempest data through the National Mesonet Program. We only recently realized how it might negatively affect CWOP. One of the topics that Synoptic and the NMP is trying to address is the de-duping of redundant data sources (as part of an overall quality-control system). It’s not the end of the world if NWS gets the same data from multiple channels, so you don’t need to worry if you’re sending your Tempest data to CWOP - they deal with redundancy already. But there is no need to submit your Tempest data through CWOP, because the data can be provided more directly to the end-users through the National Mesonet Program.
