HPC QPF GRIB Files
- The HPC makes available its Day 1-3 6-hourly QPF files in GRIB 1 format at 32km resolution.
The GRIB files are available for download via the
NCEP anonymous FTP server (ftp.hpc.ncep.noaa.gov), under:
/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.
For example, p06m_2000032112f060.grb represents the 6-hourly QPF from
54-60 hours from the 03/21/2000 1200 UTC cycle. By default, QPF GRIB data are coded in millimeters.
- 24-hour Day 3 (p24m_ccYYMMDDhhf072.grb),
48-hour Days 4-5 (p48m_ccYYMMDDhhf120.grb),
and 5-day total
