Radar Product Central
Collection Dissemination Service
(RPCCDS)

The National Weather Service is centrally collecting Level III products from 155 WSR-88D radars and soon will begin collecting Level III products derived with data obtained from 45 TDWR radars. The Level III radar products can either be obtained by connecting to the Gateway via NOAANet for an immediate receipt of the products through a LDM feed or via standard anonymous FTP from the Gateway file servers. The documentation on the products and instructions to download the software needed for the LDM dissemination can be found below.

• File Transfer documentation on how to FTP data from the Gateway file servers
• Gateway FTP description of the radar products on the file server (subdirectories and file names for retrieval)
• Directory & File Standard used for establishing Gateway file server product subdirectories and file names
• Data Formats of radar products are found in the following ICDs: ICD for RPG to Class 1 User, ICD for Product Specification. The ICDs are updated with each RPG software release. The SPG ICDs will be posted soon.
  
• Upcoming WSR-88D Software Changes that may impact RPCCDS users
  
• Central Collected TDWR Products are available soon to RPCCDS users.
