Documentation Summary

This site has the final documentation for the airborne measurements obtained from the NSF/NCAR Research Aviation Facility (RAF) EC-130Q Hercules aircraft (Tail Number N130AR) during the EPIC 2001 project which took place from 3 September to 10 October 2001.

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.161.html
• HRT    http://www.eol.ucar.edu/raf/Catalog/taplog.hrt.161.html
• (See Note in "Data Logs" section below.)

If this access method is unacceptable, data orders may be directed to the RAF Data Manager, Ron Ruth, phone:  (303)497-1084. Access is also possible through individual scientist accounts with the NCAR Computational & Information Systems Laboratory (CISL).

Both the raw and production output data have been archived to the NCAR/CISL Mass Store System (MSS) which has proven to be extremely reliable.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

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 managers or the RAF Manager:

Allen Schanot, (303)497-1063
Jeffrey L. Stith, Ph.D, (303)497-1032, Research Aviation Facility Manager
FAX phone number: (303)497-1092

We are pleased to serve as major providers of information to the EPIC 2001 program, as it was an exciting project. We look forward to assisting you and the other investigators as the analysis of those data proceeds. If I can be of further help, please do not hesitate to call.

Sincerely,

Jeffrey L. Stith, Ph.D.
Manager, Research Aviation Facility

  Note:	(updated 18 September 2007)
  The production netCDF data file headers for this project have an error in the "long_name" attribute for the variable "CS200_RPO." It should be:  SPP-200 (PCASP) Concentration (per cell) - DMT. (The probe's name was incorrectly identified as "SPP-100.")
