GMD Team Members of the Quarter
The HATS flask analysis team of Debbie Mondeel, Carolina Siso, and David Nance have provided important analyses of the recent atmospheric growth increase of CFC-11, an important ozone depleting gas regulated by the Montreal Protocol. Their contributions were critical to a recent paper by Montzka et al. (2018) on possible illegal production of CFC-11, and to a recent meeting about the Montreal Protocol. Their jobs require meticulous work on calibration, analysis, data recording, flask repair, and interaction with station staff on issues of sampling. They have helped to continue the GMD flask record from 1977 to the present.
