With the 12Z upgrade to the GFS model. I have notice a serious problem with
the data. Many of the fields are not smoothed and are very noisy, which is
causing problems for display applications. I am attaching a couple of
samples.
Is anyone else seeing these problems?

THE UPGRADE TO THE GFS MODEL WAS IMPLEMENTED AT 12Z
WED JUL 28 2010..EARLIER TODAY.
PLEASE SEE THE TIN FOR FURTHER INFORMATION REGARDING THE
SCIENTIFIC AND PRODUCT CHANGE DETAILS. IT IS EXPECTED THAT SOME
OF THE METEOROLOGICAL FIELDS THAT CUSTOMERS RECEIVE, VIA NOAAPORT,
COULD BE A BIT NOISIER DUE TO THE HIGHER RESOLUTION MODEL DATA.
IT IS ALSO EXPECTED THAT SOME PRODUCTS FROM THE
GFS...GEFS...WAVE...GFDL...HWRF AND SREF MODEL SUITES COULD BE
DELAYED/VARY BY 3-8 MINUTES ON ANY GIVEN CYCLE DUE TO THE HIGHER
RESOLUTION GFS..RUN TIME DIFFERENCES.
