  • Closing Out the Ice Formation Closure Study

    Editor’s note: Daniel Knopf is the principal investigator (PI) of the Aerosol-Ice Formation Closure Pilot Study (AEROICESTUDY). It is the first attempted study of its kind at ARM’s Southern Great Plains (SGP) atmospheric observatory. Knopf, a professor in the School of Marine and Atmospheric Sciences at Stony Brook University in New York, sent in this…

  • Eclipse’s Shadow Felt on Southern Great Plains Instruments

    While the total solar eclipse of August 21, 2017, wowed spectators throughout the United States, instruments at the ARM Facility’s Southern Great Plains (SGP) atmospheric observatory recorded data connected to the rare event. The first total solar eclipse to sweep across the United States in 99 years appeared as a partial eclipse over the SGP,…

  • Prepping an Aerosol Observing System for Delivery

    Editor’s note: Stephen R. Springston, a scientist at Brookhaven National Laboratory and lead instrument mentor for ARM’s aerosol observing system, sent this update. This afternoon, June 21, Brookhaven National Laboratory (BNL) took delivery of the enclosure for the new Southern Great Plains (SGP) aerosol observing system (AOS). This photo shows the SeaTainer sitting in its…

  • All About the Pyrheliometers: 12th Annual IPC Conference

    Editor’s Note: Craig Webb, calibration technician at the Southern Great Plains site, sent this update. Data quality of the measurements from radiometers requires accurate and regular recalibration traceable to the World Radiometric Reference, the international standard of solar radiation measurement. Every 5 years the World Radiation Center/Physikalisch-Meteorologisches Observatorium Davos in Davos, Switzerland, hosts the International…

  • ARM Radar Technician Training Course at the ARM SGP Site

    Editor’s note: Joseph Hardin, a radar engineer at the ARM Climate Research Facility, sent this update Training attendees Chris Martin and Matt Gibson working to measure a signal on the top of an X-SAPR radar. The ARM Climate Research Facility currently operates 33 radars spread over 6 sites that stretch around the world, from Antarctica…

  • Calibration Season Begins

    Editor’s Note: Craig Webb, calibration technician at the Southern Great Plains site, sent this update. A view of a collection of radiometers taken from the now closed Tropical Western Pacific facility. The ARM Climate Research Facility requires accurate measurements of solar radiation from radiometers used in ground-based networks and airborne instrument platforms. These measurements are…

  • Cow Pastures and Oil Rigs

    Me standing on top of the Radiometric Calibration Facility. It is four-thirty on a Sunday morning when my cellphone chirps, rousing me from my deep sleep. As I transition from a horizontal to vertical state, and amidst the muddled fog of dream fragments, I am struck with a thought. One that will float through my…

  • Testing the Next Generation of Radiosondes

    Editor’s note: Mike Jensen, a scientist at Brookhaven National Laboratory, sent this update. He led the Midlatitude Continental Convective Clouds Experiment, or MC3E, and is part of the translator team that creates data products from ARM measurements. Each year, the ARM Climate Research Facility launches thousands of weather balloons—radiosondes attached to helium balloons—to obtain critical…

  • You Will Be Missed, Mr. Samaras

    Around the early 1990s, the U.S. Department of Energy set up the Atmospheric Radiation Measurement (ARM) Program to collect climate and weather-related observations from across the globe. One of its first sites—now sprawling over 143,000 square kilometers and harboring 33 suites of sophisticated instruments—is in Oklahoma. Around the same time, a man working by himself…
