  • Micropulse Lidar Cloud Mask Machine Learning VAP Released for SAIL, CAPE-k

    This sample quicklook plot from the SAIL ARM Mobile Facility site shows the log of the normalized relative backscatter (log10 NRB), linear depolarization ratio (LDR), and cloud mask from the MPLCMASKML value-added product for March 16, 2022. In addition, the plot contains the machine learning model’s confidence in its prediction, as well as cloud base…

  • 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…

  • 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…

  • 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…

  • 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…

  • Microwave Radiometer Retrieval Data Now Available for SAIL

    This MWRRET quicklook image provides information from the SAIL campaign near Crested Butte, Colorado, on March 22, 2022. From top to bottom, the image shows observed brightness temperatures at 23.8 GHz (blue) and 31.4 GHz (red); retrieved precipitable water vapor from the physical method (blue) and statistical method (green); and retrieved liquid water path from…

  • Black Carbon Data Product Available for Use

    Sample plots show black carbon mass concentrations and size distributions from February 16, 2020, at ARM’s North Slope of Alaska (NSA) atmospheric observatory. On this day, smoke from biomass burning approached the NSA. The Atmospheric Radiation Measurement (ARM) user facility developed a data product for scientists to measure the black carbon (BC) mass loadings in…

  • 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 Best Estimate Data Released for SAIL Campaign

    ARMBEATM relative humidity (top) and surface precipitation (bottom) are shown for the first 120 days of 2022 during the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign. The Atmospheric Radiation Measurement (ARM) user facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the evaluation of global climate models. Two ARMBE…

  • Quality-Assured SAIL X-Band Radar Data Now Available

    A site camera on Crested Butte Mountain captures the Colorado State University X-band scanning radar during the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado. Quality-assured data from the radar are now available. During the 2021–2023 Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado, the Atmospheric Radiation Measurement (ARM)…
