**Thanks to the entire Aqua, Calipso, and Aura Teams!**

## Texas Air Quality Study 2006 (TexAQS)
mainly NOAA and State of Texas
Support new State Implementation Plan to meet EPA requirements
AIRS, TES and MISR teams for NASA
AIRS in near-real-time for flight-planning
Satellites provided large-scale context
Satellite air quality measurements contributed to Texas State Implementation Plan (SIP) to EPA.

## Regional Influences During Aug 30 - Sep 02, 2006 

**Houston Ozone AQ event – ****from REALTIME forecasts**
**Synthesis of EPA AIRNOW, NOAA P3, NASA AIRS measurements**
**and RAQMS chemical analyses **

- 24hr averaged
- ozone shows 30ppbv enhancement during the period that could be due to regional transport

**5-day Lagrangian mean ozone mixing ratio, altitude, and pbl height Houston AIRNOW sites 09/01/06**

- Daily ozone production along back trajectories results in Lagrangian mean ozone increase of
- nearly 30ppbv during previous 4 days

- Trajectories remain within boundary layer during the previous 5 days
