Hi Joseph, The three alphanumeric characters after the /p in your pattern matching line correspond to the \4 on the product-action line (i.e. the fourth set of parentheses). You should be able to cross-reference these three alphanumeric characters with the specific radar product that is listed here: https://www.weather.gov/media/tg/noaaport_radar_products.pdf What you're looking for is the three alphanumeric characters after the cccc in the WMO Header column in that PDF. For example, N0R is the 124 nmi base (0.5 elevation angle) reflectivity, NAU is the 0.9 elevation angle 162 nmi radial velocity, N0X is the 0.5 elevation angle digital differential reflectivity, etc. >Can all the above data from my pqact be obtained from the tgftp site? This depends on whether the upstream LDM that is specified in your ldmd.conf REQUEST line for the NEXRAD3 feedtype contains the specific radar products you're looking for and/or if you're additionally matching on specific radar products on the NEXRAD3 REQUEST line. If your upstream LDM server is a NOAAPort ingest server, then all of the products listed in the PDF link, above, should be available over NOAAport. (Alternatively, you could follow the instructions here: https://www.weather.gov/tg/radar to receive radar data from the Radar Product Central Collection / Dissemination Service by editing ldmd.conf and pqact.conf to request data directly from the NWS's LDM through the EXP or FT27 feedtypes. (I found that page from https://www.weather.gov/tg/radfiles under the Implementation Guide for a LDM connection. "The data can be obtained either through a direct LDM data feed from the NWS or by standard ftp. Either process follows the directory path established below." Meaning, if you go the route of requesting the radar data through a direct LDM data feed from the NWS, then all of the data from the tgftp site is also available through the NWS LDM feed.) _________________________________________ Jason N.

NEXRAD? ^SDUS[2357]. (....) ([0-3][0-9])([0-2][0-9][0-6][0-9]).*/p(...)(OKX|DIX|BOX|ENX|BGM|FTG|MPX|EMX|LOT) ???????

(and sources of that data): ftp://tgftp.nws.noaa.gov/SL.us008001/DF.of/DC.radar Can all the above data from my pqact be obtained from the tgftp site? Thanks in advance!
