READY Web Server
Accounts & Linking
How
come I can no longer automate the way I get READY meteorological
products and why do I now need to enter a random password for
every product I request?
I
am having trouble getting meteograms and other products. A message
pops up that says I don't have permission to get the information.
Can you tell me if I now need to get an account?
I'd
very much like to set up some shortcuts to the Current Meteorology
products in a similar way that some others have done for Europe
and Australia, for the regions and locations that I most frequently
access. If you'll allow this, do you have any documentation available
on the CGI parameters, etc?
Meteograms
Do
you have a description of the meteogram or profile program for
soaring pilots? (March 2004)
Stability Plots
With
regard to the stability time series plots from the EDAS data,
exactly what am I looking at? Are these model output fields (forecasts),
or am I looking at the results from assimilated data?
What
does it mean by vertical mixing in the stability plots? Does
this represent thermal height? If so, how's that different than
the boundary layer? Also, is instability simply a measurement
of lapse rate? One of the reasons for asking is that I noticed
that for one of the WMO stations I look at the vertical mixing
spike was off the chart, but the same sounding was showing a
so-so lapse rate. On another day the spike was lower while the
sounding for the same day was indicating a much stronger lapse
rate.
Vertical Profiles (soundings)
In
the text format of the forecast-model soundings, there is a section
at the beginning of the file that has four-character abbreviations
followed by numerical values. I can figure out easily what some
of these are, e.g., PRSS=pressure, T02M=temperature at 2 m, but
other abbreviations aren't so obvious to me. Is there a complete
list of the abbreviations and units?
What
is the meaning of red line and green lines on the vertical profile?
Where can I learn more about the plot?
I'd like to get the dT/dz and the potential
temperature. Could you explain me how to get those values?
Maps
Why can't I plot GDAS archive data using the
Interactive Map programs?
What
are the differences between EDAS, FNL, REANALYSIS, and NGM meteorological
datasets, because I got quite different HYSPLIT results between
them?
What
is the source of the Reanalysis meteorological data on your web-site,
and what is it's resolution and content?
In
reference to your FNL archive products, when we retrieve a map
corresponding to a specific date do we get a model predicted
field or an actual one?
Did
anyone else archive EDAS data prior to 1997?
What
is the difference between the FNL and CDC Reanalysis data sets?
Forecast Data
Is there a sanctioned way of retrieving the GFS
data 4 times a day? I don't want to use the READY web interface in
an automated script. http://www.windguru.cz/ is a good example of what I want to do, but with a subset
of data a balloonist would find useful.
I have been using the GFS model data to get
soundings to assist me in the running of advanced gliding courses
in Australia. I have been using the information for the last two
years and, to date, I have been extremely impressed by the
accuracy of the information. My query is, how is the information
derived? The nearest sites that have sounding information are
Moree, Charleville and Brisbane, the nearest being some 250km from
my location. Many thanks for a great service.
What
is the difference between the AVN, MRF and GFS models? (March 2004)
