Radar Product Central Collection Dissemination Service (RPCCDS)

The National Weather Service (NWS) is centrally collecting Level III products from 156 WSR-88D radars and 45 TDWR radars. The Level III radar products can either be obtained by directly connecting to the Gateway for an immediate receipt of the products through a LDM feed, via standard anonymous FTP from the Gateway file servers, or receipt of a OPSnet transmission. The documentation on the products and instructions to download the software needed for the LDM dissemination can be found below.
