ARM Data Show Potential of Forests to Affect a Continent’s Climate
In a Scots pine forest, ARM’s Aerosol Observing System collected data during the 2014 Biogenic Aerosols – Effects on Clouds and Climate (BAECC) field campaign in Hyytiälä, Finland. In Scandinavia and other northern lands, boreal forests produce gases that contribute to particle formation. In the atmosphere, these particles can influence cloud properties and, by extension,…

ARM’s Decadal Vision, Part 2: Data Analytics
ARM has long-term plans to improve data descriptions, internal analyses, and analytical techniques Editor’s note: This is the second article in a series about the four themes in ARM’s Decadal Vision document. After nearly 30 years of continuous data collection worldwide, the Atmospheric Radiation Measurement (ARM) user facility has archived almost 4 petabytes of data…

From Bedrock to Atmosphere: Deep Investigations Into Disappearing Snowpack
An ARM campaign in Colorado unites with two other research efforts to better understand critical mountain hydrology In Colorado, snow blankets Gothic Mountain in December 2021. How mountains acquire, store, and release water depends on an interlocking set of complex processes in the atmosphere, soils, vegetation, and subsurface. Photo is by Jeremy Snyder, Lawrence Berkeley…

UEC Profile: Jennifer Delamere, Scientist of the Arctic, Albedo, and Snow
In a whirlwind, complex career, one researcher studies arctic weather and climate at scales tiny and vast Editor’s note: This is the eighth and final article in the 2021 series of profiles on members of the ARM User Executive Committee (UEC). Bundled up against deep cold and high winds, atmospheric scientist Jennifer “Jen” Delamere prepares…

LASSO Case Study: The Complex Travel of Solar Irradiance Through Cumulus Clouds
A pair of studies point to improved realism in calculating solar radiative transfer in model simulations Shallow cumulus clouds, often oversimplified or underrepresented in models, gather over ARM’s Southern Great Plains atmospheric observatory. Two papers led by Jake Gristey could help speed and improve how models predict surface solar irradiance. Of all the energy the…

Inside Job: Studying Smoke and Fire at a Laboratory Scale
Airborne BBOP campaign inspires a slew of work in non-outdoor settings Editor’s note: This article is part of a series exploring ARM field campaigns, research, and data on biomass burning events. A smoke plume arises from a wildfire during ARM’s 2013 Biomass Burning Observation Project (BBOP), which continues to inspire laboratory (and other) studies. In…

UEC Profile: Youtong Zheng Models Complex Marine Clouds
The prolific researcher has investigated how clouds grow from parcels of air and rise fast to shade the world Editor’s note: This is the seventh article in the 2021 series of profiles on members of the ARM User Executive Committee (UEC). In the fall of 2013, Youtong Zheng posed in Jerusalem’s Old City during a…

LASSO Case Study: Modeling Farmland Soils Swept Skyward
One study, aided by ARM’s high-resolution modeling activity, simulates the escalator of turbulence that moves tilled soils high enough to influence clouds At ARM’s Southern Great Plains (SGP) atmospheric observatory, dust-producing farmland and ranchland coexist with atmospheric instrumentation. A recent SGP-focused study demonstrates a new way to accurately simulate the upward motion of agricultural dust…
