Compare ambient measurements of GEM, GOM and PHg by multiple groups for 4 weeks. Examine the response of all systems to spikes of gaseous Hg0 and HgX2 compounds. Examine the response by all systems to the presence of known or potential interfering compounds, including ozone, water vapor and other compounds. Analyze the data to quantify the level of agreement and the results of interference and calibration tests for each measurement system.
