Radar Product Central Collection Dissemination Service

The Weather Hazard Threefold

A large dome of high pressure will continue the sweltering heat in parts of the West and the central Plains.

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.
