  • 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…

  • TRACER 3-Channel Microwave Radiometer Retrieval Data Now Available

    This Microwave Radiometer Retrievals version 2 (MWRRETv2) quicklook image provides data from February 2, 2022, at the ARM Mobile Facility site in La Porte, Texas, during the TRacking Aerosol Convection interactions ExpeRiment (TRACER). From top to bottom, panels show observed brightness temperatures at 23.8 (blue), 30 (red), and 89 GHz (green); physically (red and blue)…

  • 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)…

  • TRACER Cell Tracking Data Shed Light on Convective Evolution

    Using data from the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2), the panels provide reflectivity (a, c, e, g) and Doppler velocity (b, d, f, h) processed from three range-height indicator scans (a–f) and the lowest plan position indicator scan (g, h) during the TRacking Aerosol Convection interactions ExpeRiment (TRACER) on August 17, 2022, in…

  • New Microwave Radiometer Retrieval Data Now Available

    This Microwave Radiometer Retrievals (MWRRET) quicklook image provides information from the TRacking Aerosol Convection interactions ExpeRiment (TRACER) near Houston, Texas, on June 22, 2022. 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 the physical method (blue) and statistical method (green);…

  • Atmospheric Emitted Radiance Interferometer Product Expands to 4 ARM Campaigns

    The figure shows a time series of temperature, relative humidity, and water vapor mixing ratios retrieved from AERIoe for the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign in Argentina on February 24, 2019. The Atmospheric Emitted Radiance Interferometer Optimal Estimation value-added product (AERIoe VAP) is now available in evaluation mode for the following four field…

  • New and Improved ARM Broadband Radiation Data Now Available

    Radiometers operate in mountainous terrain as part of the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado. The campaign took place from September 2021 to June 2023. Photo is by David Chu, Los Alamos National Laboratory. The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream for broadband surface irradiance measurements is…

  • Updated: New Cloud Radar Products Available From COMBLE Campaign

    Editor’s note (July 20, 2023): A new KASACRGRIDRHI evaluation release for COMBLE, which uses b1-level calibrated HSRHI data as input, is now available. The output is a single c1-level netCDF file containing calibrated radar moments remapped onto a 2D Cartesian grid. Access the data from the ARM Data Center. To cite the c1-level data, please…

  • Wind Profiles Derived From Motion-Corrected MOSAiC Lidar Data

    Using this example of a wind profile scan on a tilted surface, winds are retrieved at height z by interpolating the radial velocities in each beam to height z and then applying the standard wind retrieval technique to the interpolated data. A new value-added product (VAP) developed specifically for the Multidisciplinary Drifting Observatory for the…

  • New Cloud Microphysics and Sonde Products Available for 2 ARM Campaigns

    INTERPSONDE potential temperature output profiles are shown for November 18, 2012, during the Two-Column Aerosol Project (TCAP). The Atmospheric Radiation Measurement (ARM) user facility released two new cloud microphysics and sonde value-added products (VAPs) from the 2012–2013 Two-Column Aerosol Project (TCAP) on Cape Cod, Massachusetts, and the Green Ocean Amazon (GoAmazon2014/15) field campaign near Manaus,…
