关于我们

The Atmospheric Radiation Measurement (ARM) User Facility is a multi-laboratory, U. S. Department of Energy (DOE) scientific user facility, and a key contributor to national and international atmospheric research efforts. ARM was the first atmospheric research user facility to deploy a comprehensive suite of cutting-edge instruments to continually measure cloud and aerosol properties and their impacts on Earth’s energy balance. This strategy revolutionized scientists’ ability to collect long-term statistics of detailed cloud properties and now serves as a model for similar programs around the world. ARM provides: ? Data – Access more than 30 years of atmospheric data gathered from fixed-location observatories and field campaigns ? Observatories – Use heavily instrumented fixed-location atmospheric observatories in Oklahoma, Alaska, and the Azores, including aerial (crewed and uncrewed) and mobile facilities ? Instruments – Explore more than 400 instruments that collect data at locales spanning diverse meteorological regimes ? Campaigns – Conduct atmospheric science in strategic locations around the world ? Models – Retrieve large-eddy simulation modeling data, simulations, and analysis tools ? Publications – Discover ARM-related research on clouds and aerosols, their interaction with the Earth’s energy balance, and representation in earth system models.

  • Tethered balloon system (TBS) flights have officially launched at ARM’s Bankhead National Forest (#ARMBNF) atmospheric observatory in northern Alabama. The TBS will collect data on temperature, humidity, wind speed, wind direction, turbulence, and aerosol properties at approximately 1,500 meters above the forest floor. ?? ?? ?? Learn more about the TBS and other recent scientific activities at #ARMBNF at https://bit.ly/3XwTnJc ??: Brent Peterson, Sandia National Laboratories

  • ?? How Do We Measure Cloud-Forming Particles? ?? The Cloud Condensation Nuclei Counter (CCN) helps scientists understand how tiny aerosol particles in the atmosphere contribute to cloud formation. It works by: ?? Drawing in an air sample and exposing it to supersaturated water vapor ?? ? Encouraging water to condense onto aerosol particles ??? ?? Measuring the number and size of particles that grow large enough to activate into cloud droplets Learn more about the CCN from lead mentor Ogo Enekwizu (Brookhaven National Laboratory): https://bit.ly/4iEml2b

  • ?? New Data Available! ?? Check out Aerosol Optical Depth Best Estimate 5-Channel (AODBE5CH) production data generated for ARM’s North Slope of Alaska (#ARMNSA) atmospheric observatory! This value-added product combines individual aerosol optical depths (AODs) from various ARM instruments to provide a high-quality, nearly continuous record of AOD best estimates at five wavelengths and offers wavelength-dependent uncertainty assessments. Scientists can use the AODBE5CH data to analyze the variability of aerosol loading and its impact on atmospheric processes. ??Access these #ARMData and read more details now at https://bit.ly/4l1tafX ??: Data from a Cimel sunphotometer (top) and a multifilter rotating shadowband radiometer were used to help generate the AODBE5CH value-added product for the #ARMNSA central facility at Utqia?vik (formerly known as Barrow).

  • ?? Reminder: Abbreviated Proposals Due Tomorrow! ?? Planning to propose for the ARM ArcticShark uncrewed aerial system (UAS) deployment in FY2025? The deadline for abbreviated proposals is tomorrow, March 21! Don’t miss this opportunity to advance atmospheric research at Bankhead National Forest with ArcticShark’s cutting-edge capabilities! ??

  • Ever wondered how tiny airborne particles respond to changes in humidity? The humidified tandem differential mobility analyzer (HTDMA)—an instrument in ARM's Aerosol Observing System—helps scientists understand just that! The HTDMA uses two differential mobility analyzers (DMAs) and a humidification system to make its measurements. ?? How it works: ?? The first DMA selects dry aerosol particles of a specific size. ?? These particles are then exposed to high relative humidity in the humidification system. ?? The second (humidified) DMA measures how much the particles grow (if at all) due to humidity. ?? A condensation particle counter tracks the number of these humidified particles of varying sizes, from which a size distribution is derived. Hear from HTDMA lead instrument mentor Janek Uin of Brookhaven National Laboratory, and learn more on our website: https://bit.ly/3DPk5pM

  • ??New Data Available!?? An enhanced version of ARM’s Quality-Controlled Eddy Correlation Flux Measurement (QCECOR) value-added product has been developed, offering both new and reprocessed data. QCECOR is designed to improve the surface turbulence fluxes from eddy correlation flux measurement systems (ECORs, like the one pictured here) by applying eddy correlation corrections, determining quality-controlled energy fluxes from the corrected ECOR fluxes, and performing stringent quality control checks. ?? Access these #ARMData and details now at https://bit.ly/43RR6vY ??: An eddy correlation flux measurement system is pictured as part of the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Gothic, Colorado.

  • Happy Pi Day! ?? Let's celebrate not only this amazing number (3.14159...) and delicious dessert ??, but also pi's crucial role in atmospheric research. Hear from members of the ARM community on how pi is helping advance our understanding of the atmosphere. ???? #PiDay
