  • Aerosol Optical Depth Best Estimate Data in Production for NSA

    Time series show the combined aerosol optical depths (AODs) generated for the North Slope of Alaska central facility at Utqiaġvik (top panel) and the Atqasuk site (bottom panel). Gaps in the time series are likely associated with seasonal data availability and quality, as well as required upgrades and replacements of ground-based instruments measuring AOD. Images…

  • 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…

  • Doppler Lidar Data Products Released for 2 ARM Campaigns

    Time-height displays show a) wind speed and b) wind direction from DLPROF-WIND on October 30, 2023, on the Ellen Browning Scripps Memorial Pier in La Jolla, California, during the EPCAPE campaign. Images are courtesy of Rob Newsom, Pacific Northwest National Laboratory. The Atmospheric Radiation Measurement (ARM) User Facility operates Doppler lidars (DLs) at its fixed…

  • Cloud Type Classification Product Available for EPCAPE and CAPE-k

    Time-height displays show reflectivity (top), cloud types (middle), and precipitation (bottom) on February 1, 2024, during the EPCAPE campaign in La Jolla, California. Image is provided by Krista Gaustad, Pacific Northwest National Laboratory. The Cloud Type Classification value-added product (CLDTYPE VAP) is now available for the 2023–2024 Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) in…

  • New Aerosol Optical Depth Data Available for 4 ARM Sites

    The colors represent aerosol optical depths measured at wavelengths of 415, 500, 615, 673, 870, and 1625 nanometers (nm) with the multifilter rotating shadowband radiometer on December 13, 2023, in La Jolla, California, during the EPCAPE campaign. Data plot is by Krista Gaustad, Pacific Northwest National Laboratory. The Aerosol Optical Depth (AOD) value-added product derived…

  • Compare Modeled and Observed Clouds at COMBLE With ARM Radar Simulator Product

    Reflectivity (left) from the Ka-Band ARM Zenith Radar (KAZR) and a contoured frequency altitude diagram (right) from KAZR Active Remote Sensing of CLouds data are shown for March 13, 2020, during the COMBLE campaign. Image was generated by Meng Zhang, University of Houston, previously Lawrence Livermore National Laboratory. To facilitate the direct comparison of earth…
