  • Improved Broadband Radiation Data Available From ARM Fixed Sites

    ARM radiometers operate near Lamont, Oklahoma, on April 18, 2023. ARM file photo. The Atmospheric Radiation Measurement (ARM) user facility processes yearly data from the Data Quality Assessment for ARM Radiation Data (QCRAD) product—the recommended ARM datastream for broadband surface irradiance measurements—to produce level 2 (c2) files. These files undergo additional processing to improve the…

  • New and Improved ARM Broadband Radiation Data Now Available

    Radiometers operate in mountainous terrain as part of the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado. The campaign took place from September 2021 to June 2023. Photo is by David Chu, Los Alamos National Laboratory. The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream for broadband surface irradiance measurements is…

  • New Broadband Irradiance Data Produced for 2 ARM Sites

    This collection of radiometers at Oliktok Point, Alaska, provided continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for downwelling components. ARM stopped collecting data at Oliktok Point in June 2021 after almost eight years. New c2-level data are available from the Data Quality Assessment for ARM Radiation Data (QCRAD) product at Oliktok Point,…

  • Improved Broadband Radiation Data Quality Files Available From Southern Great Plains 

    A broadband radiometer station at ARM’s Southern Great Plains Central Facility near Lamont, Oklahoma, measures broadband solar (shortwave) and infrared (longwave) radiation. Data from this station have been processed as part of a new release for the Data Quality Assessment for ARM Radiation Data (QCRAD) product. The Atmospheric Radiation Measurement (ARM) user facility processes yearly…

  • New Broadband Irradiance Data Released for ARM Observatories

    This collection of radiometers provides continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for downwelling components. The Atmospheric Radiation Measurement (ARM) user facility processes yearly data from the Data Quality Assessment for ARM Radiation Data (QCRAD) and Radiative Flux Analysis (RADFLUXANAL) products to produce level 2 (c2) data. New c2-level data from QCRAD…

  • Radiation Data Quality VAP Expands to COMBLE and MICRE Campaigns

The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream for broadband surface irradiance measurements is Data Quality Assessment for ARM Radiation Data (QCRAD). The QCRAD value-added product (VAP) is now…

  • Radiation Data Quality VAP Data Reprocessed for SGP Broadband Radiometer Station

    The broadband radiometer station provides continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for downwelling components. An end-to-end reprocessing of data from the Data Quality Assessment for ARM Radiation Data value-added product (QCRAD VAP) is complete for the broadband radiometer station (BRS) at the Southern Great Plains (SGP) atmospheric observatory. All historical data…

  • Radiation Data Quality VAP Now Available for CACTI Field Campaign

    Preparing for the 2018–2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign in Argentina, a technician works on ARM sky radiometers on stand for downwelling radiation. These instruments are a key contributor to the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream…

  • New Radiation Data Quality VAP Release Available for Southern Great Plains

    Radiometers collect data at the ARM Southern Great Plains extended facility E31 (Anthony, Kansas). A new level 2 (c2/s2) release for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) is now available. This release covers the following 13 extended facilities at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains…

  • New Radiation Data Quality VAP Release Available for Southern Great Plains Extended Facilities

    Radiometers collect data at the ARM Southern Great Plains extended facility E35 at Tryon, Oklahoma. A new level 2 (c2/s2) release of the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) is now available for eight extended facilities at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains atmospheric observatory. This…
