The GO3 Project provides schools with an instrument package for continuously measuring ozone and meteorological parameters and uploading those parameters to a database where current and past measurements may be displayed on an overlay in Google Earth. The instrument package contains everything needed to begin measuring ozone, temperature, pressure, humidity, wind speed, wind direction and rainfall and consists of:

Ozone Monitor

The GO3 Ozone Monitor is a 2B Technologies Model 106-L Ozone Monitor with some modifications, which consist primarily of a silent, long-life air pump and a faceplate bearing the GO3 logo. The GO3 Ozone Monitor, like all 2B Tech instruments, is based on the fundamental method of UV absorbance at 254 nm, the method used by the US EPA at all of its monitoring sites. Currently, this is the most accepted means of measuring ozone. A very similar instrument, the Model 202 Ozone Monitor, is widely used by scientists and government organizations around the world for ozone measurements in remote locations where small size and low power requirements are required. Users of the 2B Tech ozone monitors include the US National Park Service, US Forest Service, Environmental Protection Agency, National Oceanic and Atmospheric Administration (NOAA), National Center for Atmospheric Research (NCAR), British Antarctic Survey, Eidgenössische Technische Hochschule (ETH) of Switzerland, and many others. 2B Tech's portable ozone monitors have been used to measure ozone in the Amazon Rain Forest, on buoys in the Arctic Ocean, throughout the winter in Antarctica, on kites flown on the summit of the Greenland ice sheet, in many of the US National Parks and Forests, and in many other places. Thus, the GO3 students make their measurements with state-of-the-art instrumentation. The GO3 Ozone Monitor (Model 106-L) is a new version of the widely used Model 202 Ozone Monitor and has been designed so that the entire instrument is mounted on a single printed circuit board (see photo). The design allows easy assembly and disassembly and minimizes the number of wiring connections, thus making the instrument easy to assemble and repair. Students and their teachers are encouraged to disassemble and reassemble the ozone monitor to better understand how it works. Technical specifications for the GO3 Ozone Monitor are identical to those of the Model 106-L and may be found at the 2B Tech website here.

Weather Station

As part of the GO3 Project, schools are supplied with the Model 6250 Davis Vantage Vue Weather Station. Davis is the leading supplier of portable weather stations, and their instruments are widely used by atmospheric scientists. The weather station measures outside temperature, barometric pressure, humidity, wind speed, wind direction and rainfall. The station is powered by its own solar panel. Data are transmitted wirelessly to distances up to 1,000 feet (300 meters) to an indoor Console. The console includes weather forecast icons, moon phase, sunrise/sunset times, graphing of weather trends, alarms and more. Also included in the GO3 package is a Davis data logger which allows the data from the weather station to be collected by the notebook computer and uploaded to Google Earth along with the ozone measurements.
