Dan Weaver is a Ph.D. student at the University of Toronto Department of Physics. His main research interest is atmospheric measurements of water vapour in the Canadian high Arctic.
His poster at the EGU 2018 presented an assessment of available satellite measurements of high Arctic water vapour in the upper troposphere and lower stratosphere (UTLS). Water vapour in this region has large impacts on the radiative balance of the atmosphere. It is also a region that has been difficult to measure for both satellites and ground-based instruments.
The main goal of the work was to assess new water vapour profiles produced by Atmospheric Chemistry Experiment satellite measurements using comparisons to coincident ground-based measurements taken by a Fourier transform infrared (FTIR) spectrometer and radiosondes located at a high Arctic observatory at Eureka, Nunavut. Additional comparisons to satellite measurements taken by AIRS, MIPAS, MLS, SCIAMACHY, and TES were included for context.
