In May and June of 1988, a major photochemistry experiment at MLO refered to as MLOPEX was conducted by the National Center for Atmospheric Research (NCAR) with additional investigators from NOAA/AL and a number of universities. The purpose of MLOPEX was to examine photochemical relationships of major odd-nitrogen compounds along with some of the odd-hydrogen and odd-oxygen compounds, and to obtain data directly applicable to modeling remote tropospheric production and loss of ozone (O3).
The experiment was such a success that NCAR returned to MLO in 1992. The study utilized four large shipping containers, the equipment was operated by up to 25 scientists and supporting crew members. Additional instruments were mounted on the MLO tower. The AEC building was used by NCAR for communications and data analysis. Study periods occurred in April and July .
