How are ozone levels measured
WebThe Ozone Monitoring Instrument (OMI) measures the total amount of ozone from the ground to the upper atmosphere over the entire Antarctic continent. The measurements … WebOne target gas is near the ambient levels of CO 2, and the other is higher than ambient. The repeat cycle of every 11 hours causes the target measurement to slowly move through the diurnal cycle because each day it is measured two hours earlier than on the previous day. This helps in determining if there are any problems related to the time of day.
