Two SOARS protégés have won awards for their presentations at the 2001 national conference of the Society for Advancement of Chicanos and Native Americans in Science.

Pauline Datulayta, a junior at the City University of New York's Queens College, won recognition for the outstanding graduate oral presentation in Geo Science/
Atmospheric Science and a $2,500 cash award. Her talk focused on the relationship between pollution distribution and atmospheric turbulence in the planetary boundary layer.
At NCAR last summer, Pauline developed a computer animation of a particle trajectory from a numerically generated turbulent flow field in the boundary layer. She created a conceptual smokestack to trace the pattern of pollution dispersion in highly convective turbulence (which generates a looping type of dispersion) and wind sheardriven turbulence (which results in plumes that linger at the chimney height). By providing scientists with a quick glimpse of the dispersion, the model may stimulate new research directions.

Theresa Jo Johnson, an alumna of California's Humboldt State University, won the prize for outstanding poster presentation in Geo Science/Atmospheric Science and a $250 cash award. She researches the vertical distribution of ozone over the Amazon rain forest by analyzing ozone profiles from a tethered balloon platform.
Theresa's work revealed a maximum ozone deposition gradient of 5.4 parts per billion at 100 meters (328 feet) above the forest and a negligible gradient above a nearby reservoir. Such estimates have large-scale implications for society because the destruction of a portion of the forest to create a reservoir or to plant crops would impair natural processes that remove ozone and other toxic compounds from the air.
"This recognition by the society is a tribute to Pauline and Theresa," says Tom Windham, SOARS program director. "And it's also a tribute to their mentors, teachers, and fellow SOARS protégés."
An additional 11 protégés gave invited presentations at the meeting.
