Greetings, all. I just joined this mailing list, so I'm new to the
game, so to speak. At any rate,
I am writing to inquire if there is any interest in the user community
in having access to higher *vertical*
resolution GFS model data than is currently available through UNIDATA?
For simplicity in the following
discussion, I will focus just on isobaric temperature data. And I
apologize ahead of time if there are any
errors in the following -- I believe it to be accurate.
To review: UNIDATA supplies 0.5 degree GFS model data now that has
temperatures
at 26 levels:
1000,975,950,925,900,850,800,750,700,650,600,550,500,450,400,350,300,250,200,150,100,
70,50,30,20,10mb. The forecasts are at 3hr intervals, out to 180
hours, available from the 00Z, 06Z, 12Z and 18Z runs.
I am aware of the availability of 0.5 degree GFS model data at NCEP that
has more vertical levels. In fact, from
what I can see, there are 47 levels for temperature: 1000, 975, 950,
925, 900, 875, 850, 825, 800, 775, 750,
725, 700, 675, 650, 625, 600, 575, 550, 525, 500, 475, 450, 425, 400,
375, 350, 325, 300, 275, 250, 225, 200,
175, 150, 125, 100, 70, 50, 40, 20, 10, 7, 5, 3, 2, 1mb. These
forecasts are also at 3hr intervals, out to 180 hours.
It must be pointed out that these GRIB1 files are typically about 225MB
each. Certainly it would not be necessary
to grab all 180 hours, if bandwidth is an issue -- for our purposes at
CIMSS, 24 hours would be sufficient.

What do folks think about getting this data? Any comments/questions?
Thank you all for your time!
Sincerely,
Jim
