MOPITT

<p>MOPITT (Measurements of Pollution in the Troposphere) is an ongoing astronomical instrument aboard <a href="/facts/NASA/TIMCV0yV">NASA</a>'s <a href="/facts/Terra_(satellite)/HFQuzF66">Terra</a> satellite that measures global <a href="/facts/Troposphere/JPDQq8cL">tropospheric</a> carbon monoxide levels. It is part of NASA's <a href="/facts/Earth_Observing_System/DvojMWq5">Earth Observing System</a> (EOS), and combined with the other <a href="/facts/Payload/wb7m7LLV">payload</a> remote sensors on the Terra satellite, the spacecraft monitors the Earth's environment and climate changes. Following its construction in Canada, MOPITT was launched into Earth's orbit in 1999 and utilizes gas correlation <a href="/facts/Spectroscopy/mj71FuNK">spectroscopy</a> to measure the presence of different gases in the troposphere. The fundamental operations occur in its optical system composed of two <a href="/facts/Optical_table/B5KL9Ivd">optical tables</a> holding the bulk of the apparatus. Results from the MOPITT enable scientists to better understand carbon monoxide's effects on a global scale, and various studies have been conducted based on MOPITT's measurements.
