Earth Day, born on April 22, 1970, is the annual day we honor our planet and bring awareness to how we can protect it.
For Earth Day 2022, the Atmospheric Radiation Measurement (ARM) user facility asked for reflections from early career scientists who study earth systems―the interlocking nature, properties, and predictive patterns of Earth’s land, oceans, and atmosphere.
Scientists associated with ARM study the interactive physics, chemistry, and biology behind climate and weather. They puzzle over the processes that create clouds, precipitation, and fluxes of energy. They investigate the atmosphere, a thin layer of gases that moderates solar radiation and holds and releases water.
Atmospheric scientists also study suspended bits of matter and moisture called aerosols. Without aerosols, there would be no clouds. Earth is shaded and shielded by clouds and nourished by their reservoirs of airborne water.
A video series here highlights the Earth Day reflections of 11 ARM-affiliated scientists in their early careers.
Some use ARM data. Others support ARM data collection as instrument mentors or technicians. All of them contribute in some way to the Earth Day 2022 theme, “Invest in our Planet.” Their data, research, and improved predictive models are investments in the climate solutions that Earth requires.
