Note that the desired pressure levels can be easily set for each variable in the NCL script.
These are currently set as follows:
Vlev = (/1000,925,850,300,200,100,50,10/)
Qlev = (/1000,850,700,500,300/)
Tlev = (/1000,850,700,500,300,200/)
Zlev = (/1000,850,500,300,200,100,50/)
NOTES
-----
1. Each of these scripts processes one of two types of data: (a) daily or
(b) monthly means. (There is also a script to process the dataset
ds118.0 which is time invariant). For the daily data, the user must
specify a starting date and a number of days. The available dates are
from 19570901 to 20020831. The requested days must all reside on the file
of the starting date. Most of the files contain one month, but for ds117.2
there are as little as 10 days on the input files. In this case, see
http://dss.ucar.edu/datasets/ds117.2/MSS-file-list.html
to help pick appropriate values for starting date and number of days.
2. For monthly means, the user must specify a starting year and a
number of years. The available years are from 1958 to 2001. Only
full years are processed for the monthly mean data.
3. All input files are in Grib format. Output files are NetCDF.
4. PN in the above tables is the ECMWF Grib parameter number. Please
note that this is not the same as the WMO Grib parameter number.
5. There are two scripts associated with each set of variables:
*.csh -- a wrapper for the NCL script so that command line arguments
can be employed
*.ncl -- actually does the work of converting Grib to NetCDF
6. Upon exit of the script, the working directory contains all input
and output data files.
7. Standard out and standard error files are produced in the current
working directory. Any intermediate files produced during the
execution of the scripts are removed from the disk.
