Texas Natural Resource Conservation Commission (TNRCC)

Baylor University Airborne Sampling Project

Under contract to the TNRCC, the Baylor University Aviation Sciences Department has been collecting airborne air quality data for approximately three years.

The Twin Otter (pictured above) is a new aircraft for Baylor University and is outfitted with a variety of instruments for measuring Ozone, Sulfur Dioxide, Oxides of Nitrogen, Particulate Matter, and Sulfates. To date, the aircraft has flown over one hundred missions in and around Texas.

Data from these missions can be downloaded from an FTP site at The University of Texas at Austin. The files on this site contain validated data collected by the airborne sampling program, time series charts of that data, and graphic images of each mission's flight path overlaid with ozone and sulfur dioxide measurements. Files are contained in zipped archives. Data and Time Series files are in Microsoft Excel 97 format and the images are in the *.gif format. Several of the data and chart files can be as large as 70MB when unzipped.
