Software
All of the R code, input files, C code, and required directory structure are
contained in a tar file that can be downloaded here:
AIRCOA_R_AND C CODE (expand with
command "tar -xvf aircoa_r_and_c_code.tar")
R Data Processing Software
These programs are described in the
AIRCOA User's Manual linked above.
All of the R code and input files are contained in a tar file that can be downloaded here:
AIRCOA_R CODE (expand with command "tar -xvf aircoa_r_code.tar")
The individual files can be accessed here:
AIRCOA/aircoa_raw_day.r
(program to process one day of data)
AIRCOA/aircoa_conc_days.r
(program to process and calibrate up to a month of data)
AIRCOA/aircoa_comp.r
(program to compare output from several units)
AIRCOA/aircoa_make_html.r
(program to create web pages
to organize files)
AIRCOA/aircoa_cylrec.txt
(cylinder IDs and install dates)
AIRCOA/aircoa_inlets.txt
(inlet heights and tubing lengths)
AIRCOA/aircoa_hiside.txt
(cylinder pressures)
AIRCOA/aircoa_timeoff.txt
(clock adjustments)
AIRCOA/aircoa_caldat.txt
(assigned values for calibration cylinders)
AIRCOA/aircoa_mfms.txt
(mass flow meter serial numbers)
AIRCOA/aircoa_mfmcals.txt
(calibrations for mass flow meters)
AIRCOA/aircoa_cylfill.txt
(dates of cylinder refills)
AIRCOA/aircoa_manfilt.txt
(manual data filtering)
AIRCOA/aircoa_fairuse.txt
(header to be added to output data files)
AIRCOA/DATA/AUTORUN/autorun.r
(script to automatically process data every day)
AIRCOA/DATA/AUTORUN/allproc.r
(script to reprocess entire dataset)
AIRCOA/DATA/AUTORUN/oneday.r
(script to process one day of data)
AIRCOA/DATA/AUTORUN/onemonth.r
(script to process one month of data)
Prior to October 2007, the aircoa executable output files with the time stamp in a binary format. These files require the following additional program called data_dump (and input file) to convert the binary times into ascii (data_dump is called by aircoa_raw_day.r):
AIRCOA/data_dump (binary
executable needed to convert binary data files from the older version of the aircoa executable)
AIRCOA/projects/CARBOE/ops1/channel_config (text input file needed by data_dump run - only needed for files from the older version of the aircoa executable)
C Instrument Control Software
Caution: This code was developed at NCAR over many years as a universal data system for a wide range of instrumentation. The code actually used by the AIRCOA system is a very small portion of the total. This code is not described in the user manual and is only provided here should expert C programmers wish to make modifications (at their own risk).
The aircoa executable can be downloaded here:
AIRCOA_EXECUTABLE (place in the directory /usr/local/bin on the Prometheus)
The rrelay executable can be downloaded here:
RRELAY EXECUTABLE (place in the directory /usr/local/bin on the Prometheus)
The aircoa and rrelay executables, as well as other output files from their compilation are contained in a single tar file that can be downloaded here:
AIRCOA_AND RRELAY COMPILE RESULTS (expand with
command "tar -xvf aircoa_c_compiled.tar")
The C code is contained in a tar and gz file that can be downloaded here:
AIRCOA_C_CODE (expand with
commands "gunzip aircoa.tar.gz" and then "tar -xvf aircoa.tar")
In addition, compiling the aircoa executable requires two additional third-party components, which may be downloaded from the following links.
