AB: As part of the INTEX Ozonesonde Network 2006 Study (IONS-06) thirty ozonesondes were launched from the Central de Ciencias de la Atmósfera (CCA) at the Universidad Nacional Autónoma de México, in the southwest sector of Mexico City, in August and September of 2006. Vertical profiles of ozone, temperature and relative humidity were measured up to altitudes that usually exceeded 30 km. These measurements are complementary to those that were made during the same period at 22 other locations in the United States and Canada. The analysis compares the profiles of ozone made in the tropical latitude of Mexico City (19°N, 99°W) with those made at mid and high latitudes. The evaluation includes day to day variability, altitudes of peak ozone and the number of distinct layers. Special emphasis will be given the unique features of the tropical ozone profiles in relationship to previous measurements that were made earlier in 2006 during the MILAGRO field project and how the observed differences are related to local and larger scale meteorology.
