Documentation Summary

This site has the final documentation for the airborne measurements obtained from the NSF/NCAR Research Aviation Facility (RAF) L-188 Electra aircraft (Tail Number N308D) during the AESOP/TEXAQS-2000 (Texas Air Quality Study) project which took place from 15 August to 15 September 2000.

The standard, low-rate (LRT), 1 sample per second (sps) data set for all flights is now available via 'ftp' or on magnetic tape, upon request. Access is also possible through individual science accounts with the NCAR Computational & Information Systems Laboratory (CISL). Software is available at RAF to view these data in a summary format.

High rate (HRT), 25 sps data have not been processed at this time but will be made available on a flight-by-flight basis. Distribution of these data will be made in response to individual requests by the project participants.

Both the raw and production output data have been archived to the NCAR/CISL Mass Store System (MSS) which has proven to be extremely reliable.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

We are pleased to serve as major providers of information to the AESOP/TEXAQS-2000 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
