Beginning April 7, 2015, NWS will more frequently disseminate
radar products generated by the NWS Supplemental Product
Generator (SPG) from the remaining FAA Terminal Doppler Weather
Radars (TDWRs) during hazardous weather. Currently, 18 TDWRs are
already disseminating this data.

The remaining TDWRs include:

The products will be provided via the NWS Radar Product Central
Data Collection Dissemination Service (RPCCDS) and/or NOAAPort.

When certain thresholds of precipitation are met, the TDWR shifts
into hazardous weather mode, also known as Volume Coverage
Pattern 80 (VCP 80). While the TDWR is in hazardous weather mode,
the short-range lowest elevation scan is repeated every minute.
In addition, most of the other short-range elevation scans and
volume products are repeated every 3 minutes.

Two example TDWR products that will be repeated every minute in
hazardous weather mode (VCP 80):

SDUS55 KPSR TV0PHX 182 Velocity (V)

Nine example TDWR products that will be repeated every 3 minutes
in VCP 80:

SDUS35 KPSR NMDPHX 141 Mesocyclone (MD)

As with other centrally collected TDWR products, National
Climatic Data Center (NCDC) will archive the additional products.
The archived products will be listed with other TDWR products
under the NEXRAD Level III tab at:

Yes, very good news. It's always mesmerizing watching storms evolve with 1 minute scans. The structures and features you miss with ~4-5min scans is astounding.
