LASSO Case Study: Simulations Sharpen View of Cloud Cover
New LASSO Data Bundles Help Close the Observation-Simulation Gap Thanks to LASSO, a cloud model simulation (above) can now more easily than ever be compared with observational data. Viewed from high above, Earth displays three color palettes that are climatologically significant. Both the brown-green land and the ice-free, deep blue oceans absorb light. Clouds, fleeting…

ARM Data Provide Insights for Developing New High-Resolution Earth System Model
E3SM will provide insights on earth system interactions in the Arctic and their influence on mid-latitude weather. In this E3SM simulation, winter storms, represented here by clouds using outgoing longwave radiation, affect sea ice coverage through their strong winds. Subsequent changes in summer sea ice cover have important effects on local and remote weather. After…

BAECC Brings a Blizzard of Strong Papers
A ‘Historically Successful’ International ARM Deployment in Finland Yields Rich Data From Novel Multi-Instrument Measurements In January 2014, mobile facility site technicians, harnessed atop a container, install a scanning ARM cloud radar at the Hyytiälä Forestry Research Station in Finland. It was part of deploying coincident wavelength multi-instrument measurements, a first during a field study…

When a Maritime Continent Gets in the Way
A New ARM Field Campaign Will Gather Data on Madden-Julian Oscillation Events Earlier this year, ARM technical project manager Amon Haruta (center) helps lay out the proposed DIMOP site in Pontianak, Borneo Island, Indonesia. Behind him, to the west, is an approaching mid-afternoon storm. Skip a flat rock across a smooth pond and it will…

LASIC Data Reveal Smoke Aerosol Presence Higher Than Previously Believed
Particles Causing Atmospheric Changes Are Common in Mid-Atlantic Boundary Layer Smoke envelops the first ARM Mobile Facility during a hazy day on Ascension Island, which is located in the South Atlantic Ocean. Researchers recently completed the first study to gather comprehensive, daily data with ground-based instruments on the properties of prolific smoke crossing the Atlantic…

Priorities Set for ARM Translators in New Three-Year Vision
Clockwise from top left, ARM translators Laura Riihimaki, Scott Collis, Connor Flynn, Shaocheng Xie, and Scott Giangrande helped develop the new three-year ARM translator vision plan. Translators serve a unique role within the ARM Climate Research Facility, directing the creation of value-added products (VAPs) and analysis tools to make ARM measurements more accessible to a…
