EOL/RAF Aircraft Platform Software Product Guide


This page describes the software that has been developed for internal use and is available to outside users.


NCAR-RAF/nimbus netCDF file conventions/format.
Examples for extracting Time from the netCDF file.

Program Descriptions

ncplot time-series plotting: https://github.com/ncar/ncplot
ncpp size-distribution plotting: https://github.com/ncar/ncpp
NetCDF Utility programs: https://github.com/ncar/aircraft_nc_utils
OAP Utility programs (including xpms2d): https://github.com/ncar/aircraft_oap
A sample netCDF file

LRT = Low RaTe. All data has been averaged to achieve 1 sample per second.
HRT = High RaTe. Variables at different rates, mostly at 25 samples per second. Rates achieved through FIR filtering.


Overview

Development platform(s)

Linux
Our primary development platform is Redhat Enterprise 7.

Other
ncplot, ncpp, and xpms2d have been ported to a number of Unix platforms, including MacOS. All of the programs will require editing the Makefile to suit your environment.


netCDF

All the programs will require that you have installed the netCDF library from Unidata (available via anonymous ftp from ftp.unidata.ucar.edu).

We have developed a set of conventions for aircraft data; NCAR-RAF netCDF conventions.


Motif

For all the GUI-based programs, you will need Motif 1.2 (or greater) installed on your system. Motif is available and packaged as openmotif for Linux and MacOS.


Building


ncplot still uses make for building. The rest of the above use scons. If you just type scons, they will build in place into a bin directory. If you prefer to install them at the system level type scons --prefix=/opt/local install


Installing

The following environment variables are used by the programs:

  setenv DATA_DIR         /my/data/directory
setenv LPDEST my_printer # May already be set.
setenv HOME ~ # Should already be set.


Known problems
