Experiment configuration file Bcmk1120.cfg, file
is here.
Bcmk1120 is just an
example name, you can chose something else,
with
my experience, it is better to have 8 characters with letters for the
first 4 characters and version number for the last 4 ones. Here Bcmk
means bench mark, 1120 shows this experiment is using the var3d version
V_11.2.0. In this file localhost refers to the name of the machine.
Here is the explanation for some variables:
- felix:
the script name to run 3D-Var
- exp:
Experiment
name, usually it is the same as your configuration file name
- gest:
the
place where the model is to be run. localhost is the name of machine
- exc4dv:
if run 4Dvar or not,
default is NON
- nml:
the directory of the namelist, which contains all the variables to
control the grid, the procedure for different goals and etc.
-
file is flnml and
simple explanation is here
- trlmod:
the the background file
(trial files)
- statbg:
the statistics for
background
- statobs:
the statistics for
observation
- statsat:
the statistics data
for satellite
- coefsat:
the data for RTTOV
- obs:
the
observation data
- obstyp:
the observation
type, there are
generally to, ai, ua, pr, sc, sw, sf, ro, etc. More information as

the output variables, you can put 'rehm, rebm, anlm' or one of them
here
rehm: high resolution increment analysis on model levels

levels
- abs:
