The WPC is currently making gridded 6-hourly QPF files (in GRIB format), in addition to a Day 3, Days 4-5 and 5-Day total, available for download via the
NCEP anonymous FTP server (ftp.ncep.noaa.gov), under:
/pub/hpc/grib/ccYYMMDD
where:
cc = century;
YY = year;
MM = month;
DD = day.
The files use the following naming convention:
p06m_ccYYMMDDhhfFFF.grb
where:
cc = century;
YY = year;
MM = month;
DD = day;
hh = hour valid from (00, 06, 12, 18);
FFF = forecast hour.
(thus, p06m_2000032112f060.grb represents the 6-hourly QPF from
60-66 hours from the 03/20/2000 1200 UTC cycle).
24-hour Day 3 (p24m_ccYYMMDDhhf072.grb),
48-hour Days 4-5 (p48m_ccYYMMDDhhf120.grb), and 5-day total
(p120m_ccYYMMDDhhf120.grb) are also available
for download.
These files are usually available around 1100/2300 UTC, with the Days 4-5 and
5-Day available around 2300 UTC.
Please read the NWS disclaimer about the
availability of this data. This is being made available on an experimental basis, and we would
like to hear if you find this data useful.
If you have any questions or
