Project 2004-125 ACME Airborne Carbon in the Mountains Experiment Principal Investigator(s):   David Schimel, et al. NSF/NCAR C-130Q Hercules (N130AR)

Documentation Summary

This site has the final documentation for the airborne measurements obtained from the NSF/NCAR Research Aviation Facility (RAF) C-130Q Hercules aircraft (Tail Number N130AR) during the ACME (Airborne Carbon in the Mountains Experiment) project which took place from 14 May through 2 August 2004.

Both the Low-Rate (LRT, 1 sample per second) and High-Rate (HRT, 25 sps, mixed) production data sets are available on-line at the URLs:

• LRT    http://www.eol.ucar.edu/raf/Catalog/taplog.lrt.125.html
• HRT    http://www.eol.ucar.edu/raf/Catalog/taplog.hrt.125.html

Both the raw and production output data have been archived to the NCAR/SCD Mass Store System (MSS) which has proven to be extremely reliable. However, we strongly urge data recipients to make their own archival copies to protect against damage or loss.

Software for viewing the Low- and High-Rate data is available from the RAF. Please consult the RAF Software Product Guide for more information on available RAF data-perusal programs.

As you proceed with analysis of your data, you may have questions, encounter problems, or uncover discrepancies or other aspects of the data set that may be of interest to the RAF and to other users. We ask that you bring these issues to the attention of the Project Manager or the RAF Manager.
