  • Characterized and Calibrated Radar Data Now Available for TRACER Campaign

    This map indicates the Houston-area radar locations during TRACER, including those of the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2), Ka- and X-band scanning ARM cloud radars (SACR), and Ka-Band ARM Zenith Radar (KAZR). ARM’s radar team cross-compared data from the ARM and NOAA NEXRAD Houston/Galveston (KHGX) radars to help determine reflectivity offsets. Map was…

  • ARM Releases Products for Evaluating Climate Model and Radar and Lidar Simulator Outputs

    The left and right panels show differences between the original and CloudSat-aligned Ka-Band ARM Zenith Radar reflectivities (top) and contoured frequency altitude diagrams (CFADs) generated with those reflectivities (bottom) for January 5, 2014, at ARM’s Southern Great Plains atmospheric observatory.

  • 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…

  • 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…

  • New ARM Data Epoch Assembled From COMBLE Campaign

    In this satellite image of the Norwegian Sea on March 28, 2020, a cold-air outbreak spurs the formation of “cloud streets.” As these broken cloud decks stream southward, they evolve into cellular patterns. In red are the two instrument locations in Norway during ARM’s Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE). This event…

  • Updated: New Cloud Radar and Sonde Products Available for TRACER, SAIL Campaigns

    Editor’s note (September 29, 2022): The end dates of the KAZRARSCL data for TRACER and SAIL have been updated below to reflect the availability of new data. The original announcement was published July 22, 2022. INTERPSONDE potential temperature output profiles are shown for October 7, 2021, during the TRacking Aerosol Convection interactions ExpeRiment (TRACER). The…

  • Satellite-Aligned Version of Ka-Band ARM Zenith Radar Product Now Available

    The top image shows best-estimate reflectivity from the Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds (KAZRARSCL) product for a sample day at the Southern Great Plains atmospheric observatory. The middle image provides the KAZRARSCL best-estimate reflectivity after statistical alignment with CloudSat. The bottom image shows the CloudSat reflectivity offset that was applied at…

  • New Cloud Radar and Sonde Products Available for BAECC Campaign

    INTERPSONDE potential temperature output profiles are shown for May 23, 2014, during the Biogenic Aerosols – Effects on Clouds and Climate (BAECC) field campaign. The Atmospheric Radiation Measurement (ARM) user facility released two new cloud radar and sonde value-added products (VAPs) from the Biogenic Aerosols – Effects on Clouds and Climate (BAECC) field campaign. BAECC…

  • Three New Value-Added Products Available for MOSAiC Expedition

    ARM instruments, including radars and aerosol instruments, operated on an icebreaker in the central Arctic during the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Photo is by Tercio Silva, then with Hamelmann Communications. The Atmospheric Radiation Measurement (ARM) user facility released three new value-added products (VAPs) from the 2019–2020 Multidisciplinary…

  • REVISED: Additional Ka-Band ARM Zenith Radar Product Releases Now Available

    Editor’s note (September 1, 2021): Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds (KAZRARSCL) data from January through June 2021 are now available for the Southern Great Plains and North Slope of Alaska atmospheric observatories. The data announcement below was originally published June 28, 2021. These plots illustrate the KAZRARSCL product for a sample…
