Overview
As of RPG Build 12.3, RPS lists may contain up to 300 products. In AWIPS only 150 different products can be added to the RPS List. Why is there a discrepancy? Well, AWIPS treats multiple elevation angles of the same radar product as a single product since they are requested at the same time. However, the RPG treats each data file it transmits as an individual product. The radar communications infrastructure supports the transfer of 300 separate files per volume scan on a LAN-to-LAN connection. As a result, the remaining documentation on this web site will refer to 300 as the product limit.
Details on the number of products in the national and local RPS lists by VCP are provided below. As a reminder, local RPS list files are saved in /data/fxa/rps-lists while the default RPS lists are available in /data/fxa/radar/lists. 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 OB 9.7.
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 only for LAN-to-LAN connections with an RPG and
- Slower connection speeds will require vastly different guidance than presented on these pages.
Because the national and local lists are combined into a single list, it's a good practice to not include files from the national list in your local RPS lists. When you do so, each request will count separately towards the final product total.
AWIPS National Dataset Products
These products are current as of AWIPS OB 9.7, and can be found locally at /fxa/data/prodList.txt. 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.
From the table below, the following products are not included in a clear-air mode VCP: VIL, STI, HI, M, TVS, and SS. All told, there are a total of 62 products in Clear Air mode (allowing for 238 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.
