Utilities for reading Chilbolton radar data and Vaisala lidar ceilometer data
Version 1.2
Copyright (C) 2000-2003 Robin Hogan
This documentation describes how to use various UNIX utilities for
reading, processing and plotting Chilbolton-format radar data,
Chilbolton FFT data, Chilbolton netCDF data and Vaisala lidar
ceilometer data.
Introduction
Scripts for processing multiple files and scans
Unix utilities
Chilbolton-format radar data
- chilinfo: reports basic information on
a radar file; useful in shell scripts
- makesum: for creates radar summary files
- chilnoise: calculates the noise levels
or the PHIDP offset of scanning data
The following programs, as well as the matlab function
loadchil below, share many of the same command line options.
- chilplot: plots radar data in png or
eps format
- chil2a: processes radar data and outputs
it as ascii
- chil2nc: processes radar data and
outputs it as netCDF
Chilbolton FFT data
- cfft2nc: converts Chilbolton FFT data
(profiles of Doppler spectra) to netCDF
- fftplot: plots Chilbolton FFT data
Vaisala ceilometer data
- ceilplot: plots lidar data in png or
eps format
- ceil2nc: converts lidar data to
netCDF
Chilbolton netCDF data
- chilncplot: for plotting radar or
lidar netCDF data in png or eps format
Note that chilncplot replaces cloudncplot
which operated only on cloud data.
- profilencplot: for
plotting profiles of lidar or cloud radar netCDF data in png or eps
format
- chilunfold: for unfolding
Doppler radar data in netCDF
- makenewsum: for making a text
summary of scanning netCDF radar data
- addcomments: for adding comments to
netCDF data files
- recalibrate: for recalibrating the
reflectivity values in netCDF radar data files
Matlab utilities
- loadchil: a `mex' program for reading
processed radar data directly into matlab
- loadceil: a `mex' program for reading
lidar data directly into matlab
Example
Development
- libchil: C library for reading and
processing Chilbolton-format radar data
- libceil: C library for reading and
basic processing of Vaisala lidar ceilometer data
- rplot: C++ library for producing
raster images, used by chilplot
