Project # 2006-146 INTEX-B2 INtercontinental Chemical Transport EXperiment, Phase B2 Principal Investigator(s):  Bill Brune, 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 INTEX-B2 project which took place from 17 April to 15 May 2006.

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.146.html
• HRT    http://www.eol.ucar.edu/raf/Catalog/taplog.hrt.146.html
• (See Note in "Data Download" section below.)

Both the raw and production output data have been archived to the NCAR/CISL Mass Store System (MSS) which has proven to be extremely reliable.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-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.

We also solicit your more general comments on the quality, usefulness, and/or new applications of the data.

We hope the support of this project provided by the Research Aviation Facility has been satisfactory.   It has been our pleasure to serve you.

We are pleased to serve as major providers of information to the INTEX-B2 program and look forward to assisting you and the other investigators as the analysis of those data proceeds.   If we can be of further help, please do not hesitate to call.

Sincerely,

Pavel Romashkin
