  • Lagrangian Large-Scale Forcing Data Released for MOSAiC

    A new Lagrangian trajectory-based large-scale forcing data product from the Atmospheric Radiation Measurement (ARM) user facility is now available for evaluation. The first data from this value-added product, known as ARMLAGTRAJ, are from November 2019 through January 2020 during the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. As part of the…

  • MOSAiC Doppler Lidar Motion Correction VAPs Now in Production

    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 a motion correction to Doppler lidar (DL) measurements collected on the icebreaker R/V Polarstern during MOSAiC. The Doppler Lidar Motion Correction…

  • Characterized and Corrected Radar Data Available for MOSAiC Expedition

    All scientists interested in researching the Arctic’s climate can now use characterized and corrected radar data from the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. These data are considered b1-level, meaning they underwent calibration, correction, and quality control processes beyond the Atmospheric Radiation Measurement (ARM) user facility’s standard quality checks…

  • Wind Profiles Derived From Motion-Corrected MOSAiC Lidar Data

    A new value-added product (VAP) developed specifically for the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition is now available for evaluation. This VAP derives profiles from Doppler lidar measurements collected on the research icebreaker R/V Polarstern, which drifted through the central Arctic during MOSAiC. The Doppler Lidar Motion Correction Wind Profiles…

  • New Data Product Determines Thermodynamic Phase of Cloud Hydrometeors

    Thermodynamic cloud phase identification is important to understand many cloud processes such as ice particle production, precipitation formation, and cloud life-cycle evolution, and it is essential to improve our understanding of cloud radiative properties and the atmospheric radiative budget. Because ice particles and liquid droplets have distinct sizes, shapes, fall velocities, and refractive indexes, clouds…

  • ARM Best Estimate Cloud Radiation Data Released for MOSAiC

    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. ARM Best Estimate Cloud Radiation (ARMBECLDRAD) data are now available from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in the central Arctic. These…

    A new value-added product (VAP) developed specifically for the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition is now available for evaluation. This VAP applies a motion correction to Doppler lidar measurements collected on the research icebreaker R/V Polarstern, which drifted through the central Arctic during MOSAiC. The Doppler Lidar Motion Corrected…

  • New Aerosol Hygroscopicity Kappa Data Ready for Evaluation

    Hygroscopicity is the ability of a particle to take up moisture from the environment and is important for understanding the formation of cloud condensation nuclei (CCN). New data from a value-added product (VAP) that calculates the hygroscopic properties of measured aerosol particles are available for three field campaigns conducted by the Atmospheric Radiation Measurement (ARM)…

  • Three New Value-Added Products Available for MOSAiC Expedition

    The Atmospheric Radiation Measurement (ARM) user facility released three new value-added products (VAPs) from the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The three VAPs are Interpolated Sonde (INTERPSONDE), Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds (KAZRARSCL), and Aerosol Optical Properties (AOP). INTERPSONDE transforms sounding data from weather…

  • Access Ice-Nucleating Particle Data From MOSAiC Expedition

    In the Atmospheric Radiation Measurement (ARM) Data Center, two principal investigator data sets on ice-nucleating particles (INPs) are now available from the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. MOSAiC provided the first data capturing the annual cycle of INPs in the central Arctic. Colorado State University researchers Jessie Creamean…
