  • New Lidar Evaluation Data Product Provides Aerosol Features

    The plot shows the aerosol features identified from the high-spectral-resolution lidar (HSRL) at the Southern Great Plains (SGP) atmospheric observatory on November 9, 2020. Panel a shows the particulate backscatter coefficient, and panel b is the associated signal-to-noise ratio (SNR). Panel c is the reflectivity factor from the Ka-Band ARM Zenith Radar (KAZR), and panel…

  • New Tethered Balloon Merged Data Available From Oklahoma Flights

    Instruments fly on a tethered balloon at ARM’s Southern Great Plains atmospheric observatory. Photo is by Brent Peterson, Sandia National Laboratories. New data from the Tethered Balloon System (TBS) Merged value-added product (TBSMERGED VAP) are available from flights at the Atmospheric Radiation Measurement (ARM) User Facility’s Southern Great Plains (SGP) atmospheric observatory. The TBSMERGED VAP…

  • New ARM Best Estimate Data Available for 4 ARM Sites

    ARMBEATM relative humidity (top) and surface precipitation (bottom) are shown for April through June 2023 during the EPCAPE campaign in La Jolla, California. Images were generated by Yuying Zhang, Lawrence Livermore National Laboratory. The Atmospheric Radiation Measurement (ARM) User Facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the…

  • Enhanced Eddy Correlation Flux Product Available

    Time series of surface sensible heat fluxes (top), latent heat fluxes (middle), and carbon dioxide fluxes (bottom) are shown from the ECOR and QCECOR value-added product at the Eastern North Atlantic atmospheric observatory on April 18, 2024. The gray line is original ECOR data. The black line represents corrected QCECOR data, and red x’s indicate…

  • New Merged Product Integrates G-1 Flight Data

    Aerosol concentration data from the G-1 ultrafine condensation particle counter are shown for an approximately three-hour flight on December 8, 2018, near Córdoba, Argentina, during the CACTI campaign. Image is from Krista Gaustad, Pacific Northwest National Laboratory. From 2010 until its final science mission in 2018, the Gulfstream-159 (G-1) aircraft served as the Atmospheric Radiation…

  • New 2- and 3-Channel Microwave Radiometer Retrieval Data Produced

    This MWRRET quicklook image provides information from the 2-channel microwave radiometer that operated on the Ellen Browning Scripps Memorial Pier in La Jolla, California, during the EPCAPE campaign on December 14, 2023. The image shows, from top to bottom, observed brightness temperatures at 23.8 GHz (blue) and 31.4 GHz (red); retrieved precipitable water vapor from…

  • Historical Video Disdrometer Quantities Processed for Southern Great Plains

    Time series of (a) rain rate, (b) radar reflectivity factor at S band, and (C) total droplet concentration from the VDISQUANTS value-added product are shown for August 24, 2012, at the Southern Great Plains Central Facility. Data plots are by Aifang Zhou, Brookhaven National Laboratory. The Atmospheric Radiation Measurement (ARM) user facility recently released more…

  • 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.
