Houston - Network of Environmental Towers (H-NET)

Project Abstract

The Gulf Star Grid will serve many applications depending on timely or real-time transmission of data from sensors as well as high-performance networking for data dissemination and analysis. The initial focus in establishing and operating the Gulf Star Grid is the effective support of collecting, analyzing and disseminating data from a network of sensors in the Houston area for the study of photochemical smog episodes in the Houston Galveston Area (HGA). Developing a good understanding of photochemical smog episodes in the HGA is essential since not only do such events represent a health hazard, but unlike the situation in a number of other major US metropolitan areas, such as Los Angeles, where peak Ozone levels have decreased significantly, little improvement in the number of exceedences of ozone alert levels has been observed in the HGA. The objective of the proposed Gulf Star Grid project is to demonstrate the feasibility of 1) using real-time measurements of air quality anomalies and events as a basis for an early warning system, 2) providing real-time air chemistry and meteorological measurements for air quality model applications, 3) establishing a data base for web based dissemination of such data, and 4) sharing such data across networks for modeling and prediction. The Gulf Star Grid will accomplish these objectives by connecting a few ground-based measurement sites forming the Houston Network of Environmental Towers, H-NET to the Grid and by employing state-of-the-art communication, data acquisition, data management and web technologies.
