  • 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…

  • Lagrangian Large-Scale Forcing Data Released for MOSAiC

    The figure provides a time series of vertical velocity (top), horizontal temperature advection (middle), and horizontal moisture advection (bottom) produced by ARMLAGTRAJ for the MOSAiC expedition from November 11 to 21, 2019. Figure is from Cheng Tao, Lawrence Livermore National Laboratory. A new Lagrangian trajectory-based large-scale forcing data product from the Atmospheric Radiation Measurement (ARM)…

  • MOSAiC Doppler Lidar Motion Correction VAPs Now in Production

    The location of ARM’s Doppler lidar on the R/V Polarstern during the MOSAiC expedition is indicated in this ARM file photo. Two value-added products (VAPs) specifically designed for the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition recently moved from evaluation to production. The Doppler Lidar Motion Correction (DLMC) VAP applies…

  • 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…

  • Characterized and Corrected Radar Data Available for MOSAiC Expedition

    From top to bottom, the figure shows the Marine W-Band ARM Cloud Radar (MWACR) raw reflectivity, MWACR corrected reflectivity, and Ka-Band ARM Zenith Radar general mode (KAZR GE) reflectivity for January 2, 2020, during the MOSAiC expedition. ARM staff applied a reflectivity offset to the MWACR data to bring them in line with the KAZR…

  • 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…
