Documentation Summary

This site contains the final documentation for the airborne measurements obtained from the NSF/NCAR Research Aviation Facility (RAF) C-130Q Hercules aircraft during the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia). This field campaign was conducted out of Iwakuni, Japan from 30 March to 4 May 2001, exclusive of ferry flights.

Orders for the low-rate (LRT; 1 sample per second) production data sets may be directed to the RAF Data Manager, Ron Ruth. The data files are also available via the NCAR/EOL Data Retrieval Web Page.

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

Software to be used in 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.

Both the raw and production output data from the C-130Q data system have been archived to the NCAR/SCD Mass Store System (MSS). The latter has proven to be an extremely reliable archival platform. However, we strongly urge data recipients to make their own archival copies in order to protect against damage or loss. These data files may be revised and replaced with updated versions if problems are discovered with particular variables and/or new variables are merged in. Please consult the project web-page to keep informed of these revisions.

Data products recorded on individual investigator data systems on the C-130Q - as well as satellite, surface, upper air, and model output data products - have been archived to the NCAR/EOL ACE-Asia Data Management web site. Users wishing to obtain any of the above-listed data products are referred to this site.

As you proceed with the analysis of C-130Q data system products, 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 other users. We ask that you bring these issues to the attention of the ACE-Asia project managers:

We look forward to assisting you and the other investigators as the analysis of these data proceeds. 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. If we can be of further assistance, please do not hesitate to call on us.
