  • Ka-Band ARM Zenith Radar Product Resumes for 2 Sites

    This set of plots illustrates the KAZRARSCL product. From top to bottom are time-versus-height plots of cloud boundaries, best-estimate hydrometeor reflectivity, and dealiased mean Doppler velocity for a sample date at Oliktok Point, Alaska. The Atmospheric Radiation Measurement (ARM) user facility has resumed production of the Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds…

  • Reprocessed Cloud Radar Spectra Data Released for CACTI Campaign

    The top right graphic is a time-versus-height image of KAZR reflectivity from the CACTI field campaign during an hourlong period on January 24, 2019. At top left, the spectrogram in height is associated with the time indicated by the dashed blue vertical line in the reflectivity image, 3.47 minutes past the hour. At bottom right,…

  • 2016 Southern Great Plains Data Added to ARM Best Estimate VAP

    ARM Best Estimate value-added product data are available now for all of 2016 from the Southern Great Plains observatory. Created specifically for climate modelers for use in the evaluation of global climate models, the ARM Best Estimate (ARMBE) value-added product (VAP) has been updated and extended to include Southern Great Plains data for all of…

  • Py-ART 1.5.0 Now Available

    This image shows how Py-ART’s new circular statistics functions can be used to extract texture information that is then used as a fuzzy logic gate classifier. These data are from the ARM C-SAPR at the Southern Great Plains site. The Python ARM Radar Toolkit (Py-ART) development team has released version 1.5.0. as an open-source Python…

  • New ARM Cloud ARSCL Evaluation VAPs Available

    Sample images from the KAZR-ARSCL VAP are showing: a) hydrometer best-estimate reflectivity, b) cloud layer boundaries, c) instruments contributing to hydrometer detection, and d) hydrometer versus clutter mask. New value-added products (VAPs) have been developed to provide best-estimate radar moments and cloud locations for the Ka-band ARM Zenith Radars (KAZRs).  The KAZR Active Remote Sensing…

  • New MICROARSCL Evaluation Data Released for Barrow, Alaska

    Four of the roughly 30 variables provided by MICROARSCL are shown here for February 13, 2012, in Barrow, Alaska. A new evaluation release of 18 months of data from Barrow, Alaska, provides the first KAZR-based Micro-Active Remote Sensing of Clouds (MICROARSCL) data from this North Slope of Alaska (NSA) site. The addition of the KAZR…

  • New Radar Data Lead to New Value-Added Product

    This sample KAZR-ARSCL plot shows data from the SGP on April 26, 2011. The top image shows the ‘reflectivity_best_estimate’ field, and the lower image shows cloud base and cloud top heights for all cloud layers detected on this day.The Ka-band ARM zenith radars (KAZRs) have replaced the long-serving millimeter-wavelength cloud radars (MMCRs). As a result,…
