Dr. Betsy Weatherhead is an atmospheric scientist who specializes in long-term observations of the Earth System. She has worked on ozone, temperature, radiation, trace gases including CO2, humidity, CH4 and various pollutants. Her work on the recovery of stratospheric ozone was featured on the cover of Nature and she has contributed to a number of international assessments including the Intergovernmental Panel on Climate Change, the International Ozone Assessments and the Arctic Monitoring Assessment Program. She has worked in the academic, public and private sectors and has worked in Europe–both in Sweden and France. Most recently, she has been working jointly with international colleagues to identify current needs for continuous Earth observations, helping to identify criteria to assure that the emerging datasets are « fit for purpose. » She is working with Jupiter and the United National Development Program to help assure that those countries most affected by the changing climate are better prepared for future risks. She has been recognized for her work with a number of awards including for her work to support under-represented groups in academia. She is a Fellow of the American Meteorological Society and hosts sessions on Renewable Energy every year with the American Geophysical Union to promote Earth Science’s contribution to lower greenhouse gas emissions.
