Barry Lefer is an assistant professor in the Department of Geosciences at the University of Houston in Texas. He earned an M.S. and Ph.D. from the University of New Hampshire and worked at the National Center for Atmospheric Research in Colorado before moving to Houston. His research has included several aspects of air quality and climate change. He worked with PolarTREC teacher Jo Dodds at Summit in 2007 and believes that there is nothing better than first hand personal experience to get students involved and excited about science.

Thanks for the question. The scientists do still need to collaborate. While we are all quite busy back home, we will have a 3 day data workshop in December to discuss the results. At that meeting we will decide who wants to write which papers. We also decide which national...{read more}
Gerty, Thanks for the question. Snowbird is only designed to measure the intensity of sunlight at various depths in the snowpack. Primary function is to determine the depth of the snow photic zone. Primarly for UV radiation, as UV is driving almost all of the in-snow chemistry we are...{read more}
Jo,
Great to hear you on the phone! Thanks for the good questions. We all really miss you. Zoey is really excited about taking your pyranometer on her traverse starting at S.P. We have talked about it, but no chance to work on teaching her about it yet because weather as been really...{read more}
