Pacific Northwest National Laboratory (PNNL) is currently seeking applications for a postdoc position in the Climate Physics Group. The primary area of research will include cloud resolving modeling of deep convective clouds and the associated detrained anvil/cirrus. The selected candidate will work with PNNL scientists to understand the microphysical and dynamical processes associated with cirrus [...]

Starting this summer, the ARM Communications Team began moving archived ARM photo and video content into both Flickr and YouTube, respectively. These popular and cost-effective social media outlets join ARM’s existing Facebook and Twitter accounts, providing additional options for sharing information with users and the public. All four sites can be accessed from the [...]

This year, the U.S. Department of Energy’s Office of Science awarded its first class of fellowships to about 150 graduate researchers in the fields of physics, engineering, biology, and physical sciences. These up-and-coming scientists were introduced to the DOE scientific user facilities during a Graduate Fellows Conference held at Argonne National Laboratory in early [...]

Radiative cooling and heating in the mid-to-upper troposphere contribute significantly to the dynamical processes and radiative balance that regulate Earth's climate. In the longwave, the dominant agent of this radiative cooling is water vapor. The dominant role of water vapor in middle-and-upper tropospheric processes is shown the spectral cooling rate profile for a mid-latitude summer [...]

Through funding from the American Recovery and Reinvestment Act of 2009, ARM is upgrading the micropulse lidars (MPL) throughout the user facility. On July 19, the first official data ingest from the upgraded instrument began arriving at the ARM Data Archive.

After nearly eleven years, the Single Frequency GPS Water Vapor Network field campaign at the ARM Southern Great Plains (SGP) site came to a close on July 1, 2010. Installed between 1999 and 2000, this network consisted of 24 GPS stations operating within an 8-kilometer radius around the SGP Central Facility near Lamont, Oklahoma. [...]

A new data set that identifies periods when Nauru data may be affected by island-influenced clouds has been produced by Chuck Long, site scientist for the ARM Tropical Western Pacific site. The Nauru island effect (NIE) data set currently covers the period from September 2005 to May 2010 and will be updated periodically as [...]

The University of Maryland, Baltimore County (UMBC) Goddard Earth Sciences and Technology (GEST) Center is currently seeking a research associate to study the horizontal and vertical variability of clouds and their consequences on atmospheric radiative fluxes and the radiation budget. The successful candidate must possess a PhD in Meteorology, Atmospheric Sciences, Earth Sciences, Physics, or [...]

The Department of Atmospheric Science at Colorado State University is seeking applicants for a senior (associate to full professor) tenure-track faculty position specializing in atmospheric radiation. The position requires a PhD in atmospheric science plus five years of experience, a record of leadership and successful grants activity, and the ability to teach graduate courses in [...]

In a key milestone for the user facility, customized containers for ARM’s new aerosol observing systems (AOS) passed acceptance testing in mid-July. Stephen Springston, a scientist at Brookhaven National Laboratory and leader of the AOS development effort, visited Maloy Mobile Storage in Albuquerque, New Mexico, to inspect and approve the containers, which were customized [...]

The ARM Data Management Facility (DMF) is the initial collection point for raw data from all the ARM sites. In June, the DMF completed installing and testing $643,000 of new computers and equipment purchased through the American Recovery and Reinvestment Act of 2009. These upgrades increase the DMF processing and storage capacity by 6-10 times [...]

June 28 marked the last official day for the Carbonaceous Aerosol and Radiative Effects Study (CARES) in Sacramento, where the ARM Aerial Facility coordinated 21 science flights by the Gulfstream-1 aircraft and obtained aerosol data from 67.4 research hours.

The formation of ice in clouds is of vital importance to life on Earth, as ice formation is one of the key processes for precipitation initiation. Since ice nucleation is tied to the action of specific aerosol particles (ice nuclei: IN) representing only 1 in 10^5 or less ambient particles, natural and human impacts [...]

Joining prestigious company overseas, the ARM kiosk is on display at the Isle of Mainau in Germany as part of an international exhibit of science and technology from May 20 through August 29. The exhibit was featured during the 60th Lindau Nobel Laureate Meeting, which took place June 27 to July 2, 2010, in Lindau, [...]

Lawrence Livermore National Laboratory (LLNL) is currently seeking a postdoc for a two-year appointment studying in the area of cumulus cloud parameterizations and climate modeling in the Atmospheric, Earth and Energy Division (AEED) for the U.S. Department of Energy's Cloud-Associated Parameterizations Testbed (CAPT) project at LLNL that aims to diagnose and improve the representation of [...]

The growth of atmospheric particles to form cloud droplets influences climate through indirect effects on cloud brightness and lifetime and changes in patterns of precipitation. Predictions of which atmospheric particles act as cloud condensation nuclei (CCN), which are the initial particles on which water condenses to grow into droplets, are complicated by their diverse composition.
