![]() ![]() She was still an undergraduate at Johns Hopkins University (B.S., physics, 1993) when she spent the summer of 1992 as an intern at UAF. It helps, too, that Delamere has been part of ARM data-gathering for so long. “That allows me to see ARM in many different ways.” “I have a wide-ranging perspective,” says Delamere. In 2023, she will take over as UEC chair. Delamere leads the UEC subgroup for enhancing communication with the satellite community and is the committee’s vice-chair. She is joined by veteran ARM data users who are experts in cloud microphysics, atmospheric aerosols, modeling, deep convection, and other research specialties. Members serve as liaisons between data users and ARM management. “I love Alaska,” says Delamere, “and I love a computer.” ‘Wide-Ranging Perspective’ĭelamere points to her many “hats” (snow researcher, instrument mentor, radiative transfer modeler, GINA director) as proof she will add depth to an advisory group she joined in January 2021: the ARM User Executive Committee (UEC). (The “G” indicates that the version is used in global climate models. Delamere has been part of the model’s development from the beginning. That’s another day job: She is part of a multistate team continually improving the computational speed and accuracy of high-performance broadband radiation code for the rapid radiative transfer model (RRTM).ĭeveloped first in the 1990s, RRTM is now in its third generation. The images are astounding, says Delamere-so much so that “to see it all, every day, live” makes it hard to look away long enough to write code. GINA harnesses imagery from polar-orbiting satellites. GINA allows her to see near-real-time imagery of Alaska from space every day, including the swirls of developing storms and, in season, the blurry drama of wildfires. ![]() Image is courtesy of the Geographic Information Network of Alaska, directed by Delamere.Īnother of Delamere’s jobs is to direct the Geographic Information Network of Alaska (GINA), a satellite direct-broadcast facility at UAF. This satellite view shows a strong cyclone approaching Alaska and the Pacific Northwest on October 21, 2021. She keeps track of a suite of instruments related to Alaskan precipitation and snow depth. She is also an instrument mentor for the Atmospheric Radiation Measurement (ARM) user facility, funded by the U.S. She is busy these days assisting on a project calculating the changing albedo-reflectivity-of snow and other surface features during spring snowmelt events. Above all, there were views of the rugged immensity of what is now Denali National Park and Preserve.ĭelamere by now is a veteran student of the arctic environment, snow science, and the atmosphere―an associate research professor at the University of Alaska, Fairbanks (UAF). Before her eyes, on the screen in their New Hampshire living room, snow-capped peaks flickered to life, moose towered in dense shrub, and bears loped in the distance. That’s what eighth-grader Jennifer “Jen” Delamere said one day in 1985 as she watched her father’s home movies of his epic road trip to Alaska. In 2009, she participated in the second phase of the Radiative Heating in Underexplored Bands field campaign (RHUBC-II) on Cerro Toco, a mountain in Chile’s Atacama Desert, one of the driest places on Earth. In a whirlwind, complex career, one researcher studies arctic weather and climate at scales tiny and vastĮditor’s note: This is the eighth and final article in the 2021 series of profiles on members of the ARM User Executive Committee (UEC).īundled up against deep cold and high winds, atmospheric scientist Jennifer “Jen” Delamere prepares to inflate some weather balloons. ![]()
