ceilplot
This program produces a quicklook on standard output from Vaisala
lidar ceilometer data read on standard input:
cat file1.dat [file2.dat ...] | ceilplot [options] > image.[png|eps]
You may find it convenient to convert the data
to netCDF and then plot it using cloudncplot.
Options
- -prefix s
- Put the netCDF files in the directory s.
- -png
- Produce PNG images. This is the default.
- -eps, -ps
- Produce encapsulated postscript images. These files can be
incorporated into documents or sent directly to a postscript printer.
- -date date
- Output only data written on the specified data (of the form
YYYYMMDD).
- -averays n
- Average groups of n rays together.
- -avegates n
- Average every n gates.
- -xfs s
- Contact the X font server s. By default the
program tries to contact unix/:7100, but this is not always
the appropriate port to use; under RedHat Linux 6.0 you should use
`-xfs unix/:-1'. If X is running then you can find the
address of the font server by running `xset -q'. In XFree86
version 4.0 the font server has been incorporated with the X server,
so an X font server needs to be run independently: as root run
`xfs -port 7100'. Unfortunately at present there are no
fall-back fonts built into the program.
- -hourrange f1 f2
- Plot data from f1 UTC to f2
UTC. The default is to plot 6 hours of data starting at the time of
the first ray. See also the -duration option.
- -rrange f1 f2
- Use f1 km and f2 km as the
horizontal range of RHI plots, rather than adapting to the data.
- -duration f
- If the -hourrange and -date options are not
specified, then the plots will start at the time of the first ray and
proceed for f hours.
- -heightrange f1 f2
- Set the height range to be from f1 km to
f2 km.
- -size {width}x{height}
- Set the size of the axes in pixels.
- -noisefactor f
- Set the noise-rejection threshold. The default value is now 4.
- -noclean
- By default an attempt will be made to get rid of the peculiar
speckle noise that very often occurs throughout a whole ray. Specify
this option if you like noise.
- -verbose
- Print progress information, such as points for each ray processed.
