From August 27 to September 8, 2006, OASIS and the HSRL were flown as part of the NOAA-led Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) and the Texas Air Quality Study (TexAQS). These two field components are part of the larger, INTEX-B (Intercontinental Chemical Transport Experiment, Phase B), a major multi-institutional intensive field program that focuses on investigating important scientific questions that are common to both climate and air quality.

The GoMACCS/TexAQS intensive field study focuses on providing a better understanding of the sources of ozone and aerosols in the atmosphere and the influence that these species have on the radiative forcing of climate regionally and globally, as well as, their impact on human health and regional haze. The area studied was Texas and the northwestern Gulf of Mexico.

The two different field components are defined by NOAA's goals for the individual segments. GoMACCS is the climate change component of this field program. GoMACCS investigated the influence of aerosols on cloud properties and the role of clouds in chemical transformation. TexAQS 2006 is the NOAA air quality component of this field experiment. TexAQS sought to investigate the sources and processes that are responsible for photochemical pollution and regional haze during the summertime in Texas.

OASIS and HSRL flew on the NASA Langley King Air B200 during GoMACCS/TexAQS -- from late August 2006 to early September. Click on a date below to view HSRL data from that day of the mission.
