Data from the TSI measurements are presented as individual images and retrievals, including daily “movies” of sky conditions above the site. ARM file photo. Environmental conditions in the tropics present unique challenges for conducting scientific research. At ARM’s Tropical Western Pacific (TWP) locale, instruments that collect climate data are continually subjected to adverse operating conditions…

ARM’s tropical convective clouds animation illustrates the difference between tropical cloud systems that form over islands versus over the ocean. ARM file image. A primary focus of ARM Education and Outreach is to develop basic science awareness and increase critical thinking skills focusing on environmental science and climate change for K-12 students. Though their efforts…

Understanding the microphysics (size, shape, velocity) of heavy precipitation is important for scientists to accurately estimate rainfall rate and for improving these parameterizations in models that predict weather. Between May and June, the ARM Southern Great Plains (SGP) site is hosting a joint field campaign for scientists from the National Center for Atmospheric Research (NCAR),…

As the name implies, a “datastream” is a continuous record of a specific type of data that is collected and saved in a time series. Occasionally, modifications are needed to update or correct a datastream. Knowing the history of changes to a datastream is a critical issue for ARM data users. Recognizing this need, the…

Established in 1989, the ARM Program is the Department of Energy’s largest global change research program. Eight national laboratories and numerous government agencies, universities, private companies, and foreign organizations contribute to its science and infrastructure using a complex network of web servers. While this distribution successfully focuses each server on a specific area of the…

A biology class at Barrow High School follows along as their teacher checks out the North Slope of Alaska DVD archive. ARM file photo. As an extension of the North Slope of Alaska (NSA) Climate Change: Science and Traditional Knowledge kiosk developed by the ARM Climate Research Facility Education and Outreach staff, a DVD archive…

Trying to describe the ARM Climate Research Facility to an educated audience is hard enough; imagine explaining it to someone who knows next to nothing about atmospheric science! Judges of the 2005 Communicator Awards print media competition apparently got the message, as they gave awards to four ARM Climate Research Facility entries in various categories.…

The 183 GHz radiometer, protected inside an insulated enclosure (inset), is installed on the roof of the primary instrument shelter at Barrow. To prevent snow from accumulating on the mylar window, a blower mounted beneath the radiometer directs air through a duct to a standard Y-shaped fitting mounted on top of the radiometer. ARM file…
