Surface Ozone Protocol

Goals for the Training Session: 

Goals for the Training Session Provide an inquiry context for the data collection and science content Provide accurate science content Review procedures for data collection Review data entry and analysis Discuss classroom implementation ideas Collect feedback from participants

Inquiry Context: 

Inquiry Context Is the amount of surface ozone related to other atmospheric phenomena? What is the variability of ozone in the atmosphere daily? Seasonally? Annually? How can you use your data collected over a period of time to predict future changes in the atmosphere?

Why do GLOBE scientists research surface ozone?: 

Considered a pollutant Globally its abundance is unknown Amount present in the air affects many other trace gases Helps assess the degree to which it is an environmental problem Why do GLOBE scientists research surface ozone?

Collecting Data: Protocol Exposing the ozone test strip: 

Collecting Data: Protocol Exposing the ozone test strip Place scanner on shaded and level surface, wait 5 minutes Record cloud protocols, current temperature, wind direction and relative humidity Turn on scanner, wait 1 minute (the scanner will automatically turn off) Turn scanner back on Calibrate scanner with unexposed ozone test strip Place this ozone test strip on monitoring station

Collecting Data: ProtocolReading the ozone test strip: 

Collecting Data: Protocol Reading the ozone test strip Place scanner on shaded, level surface; Wait 5 minutes While waiting, record cloud protocols, current temperature, wind direction and relative humidity Turn on scanner; Wait 1 minute (the scanner will automatically turn off) Turn scanner back on Measure exposed ozone test strip in scanner Record the surface ozone reading

Collecting Data: ProtocolMeasuring Wind Direction: 

Collecting Data: Protocol Measuring Wind Direction Place wind direction instrument 1 meter above ground Align base with magnetic north Place right hand on hip, left arm out straight Turn your body in line with wind sail so that your left arm is pointing in the same direction as the sail Record the direction your right elbow is pointing
