Ozone Level Detection Data Set Download: Data Folder, Data Set Description Abstract: Two ground ozone level data sets are included in this collection. One is the eight hour peak set (eighthr.data), the other is the one hour peak set (onehr.data). Those data were collected from 1998 to 2004 at the Houston, Galveston and Brazoria area.

Attribute Information:

The following are specifications for several most important attributes that are highly valued by Texas Commission on Environmental Quality (TCEQ). More details can be found in the two relevant papers.

O 3 - Local ozone peak prediction
Upwind - Upwind ozone background level
EmFactor - Precursor emissions related factor
Tmax - Maximum temperature in degrees F
Tb - Base temperature where net ozone production begins (50 F)
SRd - Solar radiation total for the day
WSa - Wind speed near sunrise (using 09-12 UTC forecast mode)
WSp - Wind speed mid-day (using 15-21 UTC forecast mode)
