  • Large-Scale Forcing Data Released for SAIL Campaign

    Continuous large-scale forcing data are now available for the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign. The Atmospheric Radiation Measurement (ARM) user facility conducted the SAIL campaign in high-altitude complex terrain near Crested Butte, Colorado, from September 2021 to mid-June 2023. Scientists can use this value-added product (VAP), known as VARANAL, to drive single-column…

  • 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…

  • Aerosol Optical Depth Best Estimate Production Data Available for 2 ARM Sites

    These time series of the combined aerosol optical depths (AODs) from 2016 to 2020 at ARM’s Eastern North Atlantic atmospheric observatory do not show seasonal patterns. Gaps in the time series are associated with data quality issues or instrument repair or replacement.

  • 3-Dimensional Cloud Positions Produced for TRACER Campaign

    This figure presents Point Cloud of Cloud Points (PCCP) value-added data from July 25, 2022, during the TRACER field campaign. The upper panel displays the distribution of the reconstructed cloud points by time and height, and the colors represent the count of the detected points in the corresponding bin. The bottom panel is a picture…

  • Tethered Balloon System Merged Data Now In Production

    During the SAIL campaign, a tethered balloon system collects data at the East River Pumphouse site south of Gothic, Colorado, on June 14, 2023. Photo is by Nathan Bilow. The Tethered Balloon System Merged value-added product (TBSMERGED VAP) and the in-cloud version of the merged product (TBSMERGEDINCLOUD) have moved from evaluation to production. Both VAPs…

  • Southern Great Plains Observatory Collects New Set of Solar Eclipse Data

    ARM now has measurements from 2017 and 2024 eclipses In a span of less than seven years, the contiguous United States has gotten to witness two total solar eclipses. The Atmospheric Radiation Measurement (ARM) user facility has collected data from both. The first of those eclipses took place August 21, 2017, with 89% coverage over…

  • Cloud Type Classification Product Released for MOSAiC, TRACER, and SAIL Campaigns

    Time-height displays show reflectivity (top) and cloud types (bottom) on June 26, 2022, during the SAIL campaign. Plots are created by the Cloud Type Classification (CLDTYPE) value-added product quicklook code. The Cloud Type Classification value-added product (CLDTYPE VAP) is now available for the following three field campaigns: the 2019–2020 Multidisciplinary Drifting Observatory for the Study…

  • ARM Releases Products for Evaluating Climate Model and Radar and Lidar Simulator Outputs

    The left and right panels show differences between the original and CloudSat-aligned Ka-Band ARM Zenith Radar reflectivities (top) and contoured frequency altitude diagrams (CFADs) generated with those reflectivities (bottom) for January 5, 2014, at ARM’s Southern Great Plains atmospheric observatory.

  • New AERI Noise Filtered Data Produced for 3 ARM Campaigns

    This quicklook image shows the time series of the radiance in window channels for Channel 1 (900 cm-1) and Channel 2 (2600 cm-1) on August 22, 2022, during the SAIL campaign. The Atmospheric Emitted Radiance Interferometer Noise Filtered value-added product (AERINF VAP) is now in production for the following field campaigns conducted by the Atmospheric…

  • New Cloud Microphysics VAP Evaluation Data Released for TRACER Campaign

    Sample plots show the primary fields from MICROBASEKAPLUS (liquid water content, liquid effective radius, ice water content, and ice effective radius) for October 14, 2021, at the TRACER ARM Mobile Facility site in La Porte, Texas. The Atmospheric Radiation Measurement (ARM) user facility’s Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) is now available for the 2021–2022…
