ACTIVE Project-Ozonesondes

The University of Manchester launched ozonesondes in co-ordination with the regular Radiosonde (temperature, humidity and wind only) launches made for operational purposes at the Darwin airport met station. These are very useful in helping to interpret aircraft ozone measurements. Given the overall focus of this campaign on the TTL region it was even more important that ozonesondes were flown to characterise the background atmosphere in which the flights took place. Ozonesondes were flown once per flight day during the campaign periods with extra flights when the background upper troposphere above Darwin was downwind of deep convection.
