This project will continue analysis of TexAQS II data collected by the Baylor Aztec as part of project H63. The preliminary data analysis indicated several occasions where primary HCHO emissions may have been observed.  These instances will be examined in detail to ascertain the responsible source.  In addition, the entire suite of measurements will be examined to quantify emission ratios of HCHO/CO and HCHO/NOx as a function of source type.  Finally, aloft data collected on the Baylor aircraft will be compared with various surface-based measurements.  Particular attention will be paid to comparison between the aircraft data and the data collected at the Mood Tower site and by the TCEQ surface network.  This portion of the analysis will serve to establish a Level 3 quality assurance (NARSTO QA/QC guidelines) benchmark for both the airborne data and the comparative surface observations.
