ARM Data Provide Insights for Developing New High-Resolution Earth System Model
After four years of development, including contributions from the Atmospheric Radiation Measurement (ARM) Research Facility, a new Earth modeling system—the Energy Exascale Earth System Model (E3SM)—is now available to the broader scientific community. The U.S. Department of Energy (DOE) Office of Science supports the E3SM project through the Office of Biological and Environmental Research. Those…

When a Maritime Continent Gets in the Way
A New ARM Field Campaign Will Gather Data on Madden-Julian Oscillation Events Skip a flat rock across a smooth pond and it will skim far and straight. Skip the rock into waves and it will juke around erratically. Now imagine that rock is skipping across the Indian Ocean as the Madden-Julian Oscillation (MJO), an Alaska-size…

LASIC Data Reveal Smoke Aerosol Presence Higher Than Previously Believed
Particles Causing Atmospheric Changes Are Common in Mid-Atlantic Boundary Layer Researchers recently completed the first study to gather comprehensive, daily data with ground-based instruments on the properties of prolific smoke crossing the Atlantic from biomass fires in Africa within a remote cloudy trade-wind regime. New data from the Layered Atlantic Smoke Interactions with Clouds (LASIC)…
