  • 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…

  • New ARM Trajectory Value-Added Product Now Available for Evaluation

    A new evaluation value-added product (VAP) from the Atmospheric Radiation Measurement (ARM) user facility provides back and forward trajectories for airmasses over ARM Mobile Facility deployments. Data from the multipurpose ARM trajectory (ARMTRAJ) VAP can provide information on the likely history of airmasses before they were observed over an ARM site, such as origin and…

  • 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…

  • Tropical Storm Hilary Is Focus of ARM EPCAPE Data Epoch

    With EPCAPE instruments in the foreground, a camera on Mount Soledad captures Tropical Storm Hilary sweeping through La Jolla, California, on August 20, 2023. View more images from the storm. A new data epoch from the Atmospheric Radiation Measurement (ARM) user facility captures a piece of history observed during a recent field campaign in La…

  • New Aerosol Hygroscopicity Kappa Data Available

    Sample CCNSMPSKAPPA plots from the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign in Colorado show kappa values within critical diameter-supersaturation field space (top) and a time series of kappa (bottom) on March 15, 2022, at ARM’s Aerosol Observing System (AOS) site on Crested Butte Mountain. The CCN particle counter and SMPS operated as part…

  • ARM Expands Collection of Merged Aerosol Size Distribution Data

    The plots show a selection of hand-labeled quality assessments (good, indeterminate, and bad) for MERGEDSMPSAPS aerosol size distributions from ARM data. These distributions and labels were used to train the MERGEDSMPSAPSML value-added product. The Atmospheric Radiation Measurement (ARM) user facility currently operates at least four instruments that measure a portion of the ambient aerosol size…

  • ARM Going Back to California for Mobile Facility Campaign

    Yearlong EPCAPE field campaign will study properties of stratocumulus clouds near San Diego The Ellen Browning Scripps Memorial Pier is a proposed ARM instrumentation site for the 2023–2024 Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) near San Diego, California. The field campaign will study low marine stratocumulus clouds at the coastal edge of the eastern…
