Global Atmospheric Chemistry Survey (GLOCHEM), ~1992 -1996 or later

  • GLOCHEM sponsored several campaigns including the Mauna Loa Observatory Photochemistry Experiment (MLOPEX). MLOPEX made concurrent measurements of the key species that play controlling roles in the photochemical transformation of ozone, odd nitrogen, and odd hydrogen species in the remote free troposphere. The results were published in JGR – Atmospheres. GLOCHEM also coordinated the Second Tropospheric Ozone (TROPOZ-II) activity, which measured chemically active gases in the free troposphere. GLOCHEM was also responsible for Measurements of Ozone in Airbus In-Service Aircraft (MOZAIC), which measured ozone and water vapor in the mid and upper troposphere by automated instrumentation aboard five commercial aircrafts.
