Biography
Dr. Baker Perry is a National Geographic Explorer and a Professor at Appalachian State University in Boone, NC. He is one of a handful of scientists working at the highest elevations of the planet to understand climate change impacts on the critical water towers that sustain hundreds of millions of people downstream. In collaboration with The National Geographic Society, the Government of Nepal, Tribhuvan University, and Appalachian State University, Dr. Perry co-led the expeditions that installed the highest altitude weather station network in the world on the south side of Mount Everest in Nepal and directs the ongoing operation and maintenance activities. The 2019 expedition was reported in a feature-length documentary; articles in the National Geographic magazine (including online here and here) have added to the coverage, with hundreds of millions of views worldwide. He and his colleagues have published many scientific papers on the network, including being featured on the front cover of the Bulletin of the American Meteorological Society in 2019 and 2022 (the latter broke the news of the summit station, recognized by Guinness World Records as the highest weather station in the world). Dr. Perry also has worked extensively at the highest reaches of the Andes Mountains in Bolivia, Chile, and Peru, where he and his teams have investigated climate and glacier changes and associated impacts on water resources.
Explorer Experience
Dr. Perry has 30 years of alpine mountaineering experience that includes multiple ascents to over 26,000 ft on Mount Everest in Nepal Himalaya and over 21,000 ft in the Andes for as part of scientific research expeditions. He has spent extensive time working on glaciers above 16,000 ft – nearly six months in total, including almost one month above 20,000 ft. He has climbed to his team’s weather station at 18,536 ft on the summit plateau of the Quelccaya Ice Cap in Peru 22 times since 2014.

Scientific Credentials
Since receiving his Ph.D. in 2006, Dr. Perry has published 47 research papers that have been cited over 1,000 times. He is a member of the American Meteorological Society, American Geophysical Union, and the American Association of Geographers.
Research
Dr. Perry’s research interests include alpine precipitation, snow and ice, glacier-climate interactions, and climate change. Mountain regions serve as a focus, with specific interests in the Himalayas, Andes, and Appalachians. His current research is organized around three major topics:
1. Meteorological Research on Mt. Everest: Recent research activities include installation of a network of meteorological stations – including the two highest in the world – in the Khumbu Himal (Everest) region of Nepal as part of the National Geographic and Rolex Perpetual Planet Everest Expedition in April/May 2019. The network will greatly improve climber safety on the main climbing routes on the south side of Mt. Everest through real-time meteorological monitoring and bias correction of numerical model output. The highest stations in particular have enabled the first in-situ characterization of the climate at the highest points on Earth and will improve paleoclimatic reconstructions from nearby ice cores.

2. Precipitation-Climate-Glacier Interactions in the Tropical Andes Mountains: Research priorities include investigating precipitation patterns and processes across the Andean region, investigating the atmospheric influences on oxygen stable isotopes and trace elements preserved in high-elevation snowfall, and decoding multi-centennial climate histories from tropical Andean ice cores. This work was supported by two grants from the National Science Foundation and currently by National Geographic and Rolex. As part of these projects, Dr. Perry has installed comprehensive precipitation monitoring stations on the Quelccaya Icecap in Peru at 5,650 m and at the Chacaltaya Observatory at 5,160 m in Bolivia. Along with Dr. Gino Casassa and other Chilean partners, Dr. Perry installed the highest weather stations in the Americas at 6,505 m on Tupungato Volcano in the Chilean Andes in 2021.

3. Snowfall Patterns and Processes in the Southern Appalachian Mountains: Research activities include investigation of multiscale atmospheric processes influencing snowfall formation, from the hemispheric (e.g., Arctic Oscillation and El Niño-Southern Oscillation) to the cloud microphysical (e.g., snow particle type and degree of riming, moist layer temperature and thickness). Dr. Sandra Yuter (NCSU), Dr. Douglas Miller (UNCA), Stephen Keighton (NOAA-NWS), and the Northwest Flow Snowfall Discussion Group are important partners in this ongoing project. A comprehensive snow and precipitation monitoring station was installed at 1,875 m asl on Roan Mountain, NC, in 2012. Recent publications include the following:
