Calibration results are available in JSON format. This format will allow the user to download and save the results as a file, which can be used for further analysis. The results will be formatted like:

 [
    {
        "fill_code": "A", 
        "num_samples": 3, 
        "instrument_code": "S5", 
        "flag": ".", 
        "date": "2005-07-06", 
        "std._dev.": 0.022, 
        "tank_pressure": 2000, 
        "parameter": "CO2", 
        "value": 402.920, 
        "time": "12:21:00", 
        "serial_number": "CA06244", 
        "type": "NDIR"
    }, 
...
] 

This shows the results of a single calibration. There would be multiple sections enclosed by curly braces {} for results with more than 1 calibration.

Using the results

Programming languages most likely have a mechanism for reading json formatted data (see the json.org website for links to appropriate software). For example, in python, the 'json' package can be used to read in and decode a json formatted file.
import json

f = open("CA06244.json")
data = json.load(f)
for row in data:
        for k in sorted(row.keys()):
                print "%10s" % row[k],
        print
which would result in:
2005-07-06          A          .         S5          3        CO2    CA06244      0.022       2000   12:21:00       NDIR     402.92
2005-07-08          A          .         S5          3        CO2    CA06244      0.009       2000   12:13:00       NDIR    402.997
2005-07-11          A          .         S5          3        CO2    CA06244      0.009       2000   13:46:00       NDIR    402.978
2013-02-07          A          .         L9          3        CO2    CA06244       0.01       1800   21:01:00       NDIR    402.908
2013-02-09          A          .         L9          3        CO2    CA06244      0.005       1800    0:51:00       NDIR    402.914

Using the API

There is a web api that you can use to get results for tank calibrations from NOAA/GMD CCL website without filling in the web page form. The main URL is

http://www.esrl.noaa.gov/gmd/ccl/getresults.php

There are 3 options to include in the URL, 'sn=serial number', 'gas=co2', 'format=json', e.g.

http://www.esrl.noaa.gov/gmd/ccl/getresults.php?sn=CC71623&gas=co2&format=json

will return json CO2 data for tank CC71623. The 'sn=' option is required, and the 'format=json' is required to get the json format, otherwise you'll get an html formatted response. The 'gas=' part is optional, if not included results for all gases will be returned.

For example, you can use the 'wget' program to retrieve and save calibration results:

 wget -O tst.json "http://www.esrl.noaa.gov/gmd/ccl/getresults.php?sn=CC71623&gas=co2&format=json" 

which places the results in a file called 'tst.json'
