Welcome to the Routine Product Set (RPS) list decision aid from WDTD. This page provides general guidance for setting up VCP (Volume Coverage Pattern)-specific and event-specific RPS lists. Every office has its own unique needs in the generation of radar products. As a result, your lists may not match what we show here. If you do have a question, or see a descripancy in our lists, please e-mail so I can contact you. Additional field input is strongly encouraged.

Overview

As of RPG Build 12.3, RPS lists for may contain up to 300 products (except for backup connections, where the limit is 150 products). There is a different, more practical, limitation on the number of products an office may request: The product distribution communications between the RPG and the local office's AWIPS. The primary AWIPS connection to a NWS radar can handle a full RPS list under almost any circumstance. Primary AWIPS connections to a DoD or FAA radar are almost always slower than those to a NWS radar. However, primary connections to FAA radars are much more susceptible to load shedding at faster VCPs like 12 or 212. Likewise, supplemental or temporary backup connections to any radar are much slower than a primary connection. As a result, you will need to be judicious with the products you request via a RPS list on these connections because you will not be able to request as many products as you are otherwise used to receiving.

Details on the number of products in the national and local RPS lists by VCP are provided below. The products that are automatically added to the list the RPG uses varies depending on the VCP used. Click on the collapsible panels below to view the full list used for clear air and precipitation VCPs. These lists are current through AWIPS 17.1.1.

NOTE: RPS list files are saved in multiple locations on your office AWIPS. When you make edits to your RPS lists, make sure to:

  • copy any lists you edit to dx1:/awips2/rcm/data/config/drop-ins AND
  • ensure your lists follow the proper naming convention (e.g., KLWX.storm.VCP12, KGWX.clear-air.VCP32) so that the Radar Server will handle them properly when changing VCPs.

Guidance for local RPS lists for each of the VCPs are included on linked pages at the bottom of this page. While perusing these pages, assume the following:

  • RPS list guidance on these pages is for primary AWIPS connections with a dedicated DoD or NWS RPG and
  • For primary FAA, supplemental, or temporary backup AWIPS connections, slower connection speeds may require a shorter list of products than those presented on these pages. RPS lists from these connections will want to balance your goals (e.g., supplemental radar site samples section of CWA better than primary radar) verses your wants (e.g., the hightest resolution base data analysis for all elevation angles).

Because the national and local lists are combined into a single list for primary and backup situations, there's no need to to include files from the national list in your local RPS lists. However, AWIPS is smart enough to identify products listed in both places so that a product isn't requested twice. If you are using a RPS list to request radar products through a supplemental connection (or if your office is using a backup connection over the WAN for an office to gain situation awareness prior to switching officially to service backup), things work differently. In these cases, you will need to do the following:

  • Most products from the national RPS list are transmitted to all offices via the SBN. Those products from the national list not received via the SBN include:
    • Spectrum Width (28 & 30),
    • Composite Reflectivity (38),
    • Hail Index (59),
    • Tornado Vortex Signature (61),
    • Storm Structure (62),
    • Layer Mean Reflectivity (65, 66, 67, & 90), and
    • Supplemental Precipitation Data (82).
  • Include any of these products from the national list you want to see on your local RPS list for a supplemental connection,
  • Structure your list so the most important products are listed first (i.e., if loadshedding does occur, make sure the most important products are received), and
  • When loadshedding occurs, consider removing any derived products from your list that your office already receives over the SBN for that site (i.e., products may be a little slower coming in, but there's a better chance you receive all the products you want).

AWIPS National Dataset Products

These products are current as of AWIPS 17.1.1. There are some minor differences between the clear air and precipitation VCPs. Expand the collapsible panels below to see a complete list that is included for each. The products in the table below are not listed explicitly on local RPS lists. When local lists are created or edited, only products not included on the national list need to be selected. The only constraint on local lists is that the total number of products (local + national) cannot exceed 300.

All told, there are a total of 62 products in Clear Air mode (allowing for 232 products on a local RPS list) and 68 products in Precip mode (84 products if operating in VCP 12/212) allowing for 232 products (or 216 products in VCP 12/212) on a local RPS list.
