Lower Rio Grande Valley Transboundary Air Pollution Project (TAPP)

摘要

The Lower Rio Grande Valley Transboundary Air Pollution Project (TAPP) was a U.S.-211u001eMexico Border XXI project to find out if air pollutants were moving across the 211u001eborder from Mexico into the Lower Rio Grande Valley of Texas and to see what 211u001elevels of air pollutants were present. Ambient measurements and meteorology were 211u001ecollected data for a year (March 1996-March 1997) at three fixed sites in and 211u001enear Brownsville, Texas very close to the U.S.-Mexico border on a continuous and 211u001e24-h internal basis. Overall levels of air pollution were similar to or lower 211u001ethan other areas in Texas and elsewhere. Based on wind sector analyses, transport 211u001eof air pollution across the border did not appear to adversely impact air quality 211u001eon the U.S. side of the Valley. Southeasterly winds from the Gulf of Mexico were 211u001elargely responsible for the clean air conditions.
