Toolkit for ARM Radar Data Previewed at Workshop
In late November, more than 100 radar experts from around the United States gathered at the University Corporation for Atmospheric Research in Boulder, Colo., to discuss how research radars can address critical science questions over the next 20 years and to identify related capability gaps. During the workshop, Scott Collis, ARM precipitation radar scientist from…

News Tips from 2012 AGU Fall Meeting
Next week, ARM’s scientific users are presenting dozens of oral and poster sessions describing their research using data from the user facility at the 2012 American Geophysical Union Fall Meeting. Nearly 20,000 researchers from around the world will gather in San Francisco to attend the largest worldwide conference in the geophysical sciences.

Workshop Identifies Critical Climate Science Challenges
Clouds and aerosols remain as major sources of uncertainty in computer models of Earth systems. In large part, this uncertainty is due to a lack in understanding of how water (in all its phases) couples to circulations and to the difficulty in coupling the Earth’s surface and atmospheric modules in the models. Key to the…

Unmanned Aircraft Test Flights Completed at Oliktok Point
On October 22, a small flight team from New Mexico State University (NMSU) began the first in a series of test flights (see YouTube video) for the ARM Facility to evaluate various unmanned aerial systems (UAS) in the frigid Arctic conditions at Oliktok Point, Alaska. For eight days, the team conducted and documented short flights…

New Flagship Data Product Launched
The new flagship product ARM Best Estimate (ARMBE) has launched with the release of ARM Best Estimate Cloud Radiation (ARMBECLDRAD) and ARM Best Estimate Atmospheric Measurements (ARMBEATM) data sets, formerly under the Climate Modeling Best Estimate VAP. ARMBE will represent all of the ARM best estimate value-added products (VAP).

Surface Cloud Condensation Nuclei Average Evaluation Product Available
Aerosol observing systems (AOS) at ARM’s sites measure cloud condensation nuclei (CCN) at several supersaturations using a single-column CCN counter. The Average of Cloud Condensation Nuclei from AOS (AOSCCNAVG) value-added product (VAP) was developed to consolidate the relevant CCN parameters into a single file and average data over the 5-minute integration time of each percent…

New Evaluation Product Estimates Aerosol Properties
The MFRSR-Column Intensive Properties (MFRSRCIP) value-added product (VAP) has been developed for estimating the microphysical (e.g., size distribution) and optical (e.g., single-scattering albedo and asymmetry factor) properties of aerosols. Size distribution retrieval is based on multifilter rotating shadowband radiometer (MFRSR) measurements of the direct irradiance at five wavelengths (415, 500, 615, 673, and 870 nm)…

Convective Vertical Velocity Data Ready for Evaluation
The new Convective Vertical Velocity (CONVV) value-added product uses observations from Doppler weather radars and other instruments to produce a best estimate of convective vertical velocity. This evaluation product is available for a few key cases during the Midlatitude Continental Convective Clouds Experiment field campaign at the ARM Southern Great Plains site. Convective processes play…

Now We’re Cruising
Editor’s note: As part of the preparations for the upcoming Marine ARM GPCI Investigations of Clouds (MAGIC) field campaign, principal investigator Ernie Lewis shares his news of the deployment installation. I was in Los Angeles again last week to see the successful installation of the MAGIC instruments aboard the Horizon Spirit! It was great to…
