SHARP - Study of Houston Atmospheric Radical Precursors


Campaign Intensive Dates 15 April – 31 May, 2009

Based on the TexAQS-II and TRAMP findings concerning radical processes in the Houston atmosphere, the SHARP project intends to investigate the following processes:

  1. The contribution of direct emissions of radical precursors HCHO and HONO from flares, stacks, and other point and mobile sources.
  2. The identification of formation pathways of HONO (Night/Day, surface, heterogeneous, homogenous).
  3. Impact of of soot (fresh and coated) on chemistry, radiation (photochemistry/climate), and dynamics.
  4. The ambient levels of ClNO2 in Houston and potential as a radical source.
  5. The relative importance of measured radicals and other “missing” radical sources.
  6. Identify important Springtime ozone formation mechanisms in Houston.

Reducing uncertainties surrounding these processes will improve our ability to model radicals and ozone formation.

Forecast Picture of the Day

Forecast 30 May 2009

TCEQ Ozone Alert Day

Tonight: mostly clear with lows in the mid 60s. North wind around 5 mph becoming light and variable.

Saturday: sunny with a high in the low 90s. North wind around 5 mph becoming southeast. This wind direction shift might possibly cause some recirculation of pollution.

Saturday Night: partly cloudy with a low in the mid to upper 60s. South wind between 5 and 10 mph.
