delay for some products. Here is part of a directory listing for one

The filetimes can be about a minute later than when the data actually
arrive on our actual NOAAport system, since the raw data for a 1-minute
interval are put into a file and then sent to my server (listing above)
and acquired via ldm. There is so much data that it can't be
instantaneous, especially since the NWSTG channel also handles all
conventional data and model data. The precip data does seem to lag the
N0R data and probably due to the order inwhich the products are
transmitted. Note: the times in the filenames above do correspond to
data observation times.
