New Campaign Guidance, New Review Deadlines—Even for Smaller Campaigns
Feb 08, 2016 [ Facility News ]       
Did you know? In November, new field campaign guidelines were published that changed the review process for field campaign submissions, particularly for smaller field campaigns. In the past, smaller field campaigns were reviewed and approved on an ongoing basis. Now, smaller campaigns may still be submitted at any time; however, they will only be approved on [...]

ENA’s Newest Instruments Support Most Extensive Marine Cloud Data Set
Feb 08, 2016 [ Facility News ]       
An elderly farmer sings in Portuguese as his donkey carries him down the steep cobbled roads to a village below. Hydrangeas and cedar perfume the air around bubbling volcanic geysers and lagoons. A thousand miles from anywhere, Graciosa Island hosts some of the world’s most advanced atmospheric instrumentation that scientists rely on to advance climate [...]

MAGIC Continues to Inspire Insights
Feb 08, 2016 [ Feature Stories and Releases ]       
Because they cover so much of the Earth and reflect large amounts of sunlight, marine clouds play an especially critical role in climate and climate research. However, most non-satellite investigations of such clouds have been relatively short-term (~one month) in fairly small regions. The Marine ARM GPCI Investigation of Clouds (MAGIC) field campaign changed that by placing the second ARM Mobile Facility on the Horizon Spirit in 2012 and 2013.

Scientists Study Clouds’ Impact on West Antarctic Ice Melt
Jan 19, 2016 [ Feature Stories and Releases ]       
It has been half a century since the West Antarctic atmosphere has been studied in detail and an “unprecedented deployment” of instruments from the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility is now delivering data that could help scientists understand how clouds affect melting glaciers.

Radar Calibration, Grooming, and Alignment at the ARM Oliktok Point Site
Jan 18, 2016 [ Blog, Field Notes, North Slope of Alaska ]       
Before a radar site is "turned on" to the public, there are many steps required to make sure the data are of the highest quality, and satisfies the requirements for scientific usage. One of the primary steps is calibration of the radar system to ensure measurements are accurate and repeatable. An entire suite of performance tests [...]

Top of the World
Jan 18, 2016 [ Blog, Field Notes, North Slope of Alaska ]       
Stepping off the plane in Barrow, Alaska, feels like stepping into someone's family reunion. The single-terminal airport was packed with people, but not with passengers flying south; family and friends flooded the small room, yelling of happy words echoed each other. Everyone was smiling and catching up, while I stood there wide-eyed, surprised how casual [...]

All About the Pyrheliometers: 12th Annual IPC Conference
Jan 18, 2016 [ Blog, Field Notes, SGP ]       
Every 5 years the World Radiation Center/Physikalisch-Meteorologisches Observatorium Davos in Davos, Switzerland, hosts the International Pyrheliometer Comparison (IPC). Participants bring their instruments to the IPC and receive the transferred World Radiometric Reference (WRR) standard. This year was the 12th annual conference, and my fourth time attending. The purpose of this conference is to provide participants with [...]

Workshop Features ARM Data
Jan 18, 2016 [ Facility News ]       
In November 2015, the First Workshop on Data Science, held in São Paulo, Brazil, was attended by 65 scientific experts to discuss national and international initiatives for data science that contribute to solving challenges in the context of open data science in Brazil. During the 2-day conference, Giri Palanisamy, ARM Data Services and Strategy Team Manager at [...]

Radiative and Thermodynamic Responses to Uncertainty in Aerosol Extinction Profiles
Jan 18, 2016 [ Research Highlights ]       
Aerosol radiative effects are of great importance for climate simulations over South Asia. For quantifying aerosol direct radiative effect, aerosol optical depth (AOD) and single scattering albedo (SSA) are often compared with observations. These comparisons have revealed large AOD underestimation and SSA overestimation in models over this region. Aerosol vertical distributions have received less scrutiny [...]

A New Model for Liquid Water Absorption
Jan 08, 2016 [ Research Highlights ]       
Liquid water path (LWP) is a critical measurement for a wide range of atmospheric studies, as the amount of liquid in a cloud is critical to understanding many cloud processes. For example, the radiative impact of the cloud (in both the longwave and shortwave portions of the spectrum) depends heavily on the LWP. Thus, [...]

The Role of Shallow Cloud Moistening in MJO and Non-MJO Convective Events over the ARM Manus Si
Dec 11, 2015 [ Research Highlights ]       
Moistening by shallow clouds has been assumed to be partially responsible for the observed increase in low-level moisture leading to convective peaks of the Madden-Julian Oscillation (MJO). In this study, we move beyond the argument for the moistening role of shallow clouds in the MJO that is simply based on simultaneous increases in both low-level [...]

Evaluation of Subgrid-Scale Hydrometeor Transport Using a High-Resolution CRM
Dec 11, 2015 [ Research Highlights ]       
Clouds moderate the climate system through direct impact on surface hydrology, as gatekeepers for the sun’s energy-in/energy-out flux, and by stabilizing the atmosphere through vertical redistribution of heat and moisture. Turbulent convective clouds and storms are especially efficient at moving moisture and heat in the atmosphere. But because the structure of these clouds is not [...]
