ARM Scientists Lead International Radiation Symposium in Brazil
The ARM Science Team showed up in force at the 2008 International Radiation Symposium (IRS), held August 3-8 at Foz do Iguaçu, Brazil. The goal of the symposium is to provide a venue to present up-to-date results about the current problems in atmospheric radiation and to encourage the exchange of ideas within the international community.…

21st Century “Paper Boy” Begins Delivering ARM News
Like a modern day paper boy, RSS (short for Really Simple Syndication) is a web-based subscription service that delivers Internet news right to your doorstep—or web browser, in this case. This week, the ARM website joined legions of other websites by adding an RSS “feed” capability to our new ARM News Center. […]

New Ceilometer Evaluated at Southern Great Plains Site
Dan Nelson, SGP facilities manager, inspects the new ceilometer during its evaluation period on the platform of the SGP Guest Instrument Facility between June and July 2008. To analyze cloud properties, ARM scientists use data from an instrument called a ceilometer. This instrument transmits pulses of light into the sky and receives return signals to…

Facility Update Highlights Progress
As the ARM Climate Research Facility has grown, so has its bimonthly report. With key accomplishments and activities encompassing the entire ARM infrastructure, the “Operations Update” report has been renamed “Facility Update.” Along with this change, the report’s web page has a new, more streamlined look that provides more information at a glance. Stay tuned…

Southern Great Plains Gets an “Assist” for Instrument Intercomparison
In July, the SGP site hosted an instrument intercomparison between the AERI and the new ASSIST instrument, shown above. One instrument scientists use to obtain measurements important for climate studies is an atmospherically emitted radiance interferometer, or AERI. This sophisticated instrument measures the absolute infrared spectral radiance of the sky directly above the instrument. In…

Second Version of Long-Term Climate Modeling Best Estimate Data Released
Version 2 of the Climate Modeling Best Estimate includes the data source information for cloud fraction, as depicted in this data plot. With major improvements in the cloud fraction, cloud liquid water path (LWP), precipitable water vapor (PWV), and surface radiative fluxes, a new version of the “Climate Modeling Best Estimate” (CMBE) is now available…

Extract This! Enhanced Visualization Tool Available at the Data Archive
Custom 2-day plot of downwelling shortwave and longwave radiation made using the enhanced NCVweb feature. Like many scientific organizations, the ARM Data Archive stores and distributes atmospheric data from the ARM sites in Network common data form, or NetCDF. This file format applies names or attributes to the various layers of data for efficient identification…

New Report Details One-of-a-Kind Data Quality Assurance Approach
With about 315 instruments systems operating 24/7 at locations around the world, dedication to data quality is a hallmark of ARM. ARM file image Very few long-running (10+ years) field based measurement programs have the diversity of instruments and data types that the ARM Climate Research Facility does. This month, the ARM data team published…

Interagency Effort Will Help Dial In Carbon Profiles
A graduate student from Penn State releases a weather balloon to support the CO2 DIAL field campaign. Soundings are focused on daytime measurements, when sunlight heats the Earth’s surface, creating convection and resulting in a well-mixed boundary layer. (Photo credit: Grace Koch, NASA Langley) Beginning in June, ARM is supporting an offsite field campaign in…

ARM Science Liaison Chairs Climate Symposium at International Conference
Known for its emphasis on “green” living, Portland, Oregon, hosted the A&WMA’s 101st Annual Conference and Exhibition. With a theme of “Integrating Science and Sustainability,” the Air and Waste Management Association (A&WMA) 101st Annual Conference and Exhibition was held on June 24-27 in Portland, Oregon. Dr. Sylvia Edgerton, ARM Science Liaison, attended the meeting and…
