John Gallagher

John Gallagher has been a CANDAC site operator at PEARL (Eureka, NU) since June 2017. John is a meteorologist who has specialized in mountain meteorology, air quality, and polar climatology, with an emphasis on data collection and quality control. John earned a Bachelor of Science degree in Meteorology at the University of Utah and a Master of Science degree in Geography at the University of British Columbia. His work experiences in the high latitudes have brought him to northern Alaska, Greenland, and Antarctica, including two winters at the South Pole. While not in the polar regions, John lives in British Columbia, where he enjoys spending time in the mountains skiing, hiking, and trail running.

Dr. Pierre Fogal

I am the CANDAC/PEARL site manager responsible for over-seeing day-to-day operations on site and the organization of visits, campaigns, etc. to the PEARL site. My research instruments include infra-red spectroscopic measurements of atmospheric composition. Techniques used include both "transmission" where the infra-red energy transmitted through the atmosphere is measured , as well as "emission" where the energy is actually emitted by the atmosphere itself. These measurements are usually carried out by using a Fourier Transform Infra-Red (FTIR) spectrometer. Non CANDAC/PEARL areas of research include similar measurements from other locations and from stratospheric balloon platforms. I have an interest in related spectroscopic measurement techniques including long-path FTIR.
