  • Merged Multisensor Cloud-Precipitation Mask and Cloud Type Data Now Available for GoAmazon2014/15

    The example plot shown here is from a merged RWP-WACR-ARSCL data set. Key: a) WACR reflectivity; b) RWP reflectivity; c) new RWP-WACR-ARSCL cloud mask; d) cloud-type classification; e) microwave radiometer (MWR) retrieved liquid water path (blue), present weather detector (PWD) rain rate (black), and tipping bucket rain rate (red). The black dots in panels (a,…

  • ARM Cloud Radar-Remote Sensing Evaluation Data Available for LASIC Campaign

    Plots from the WACR-ARSCL value-added product show reflectivity best estimate (top) and mean Doppler velocity (bottom) as captured February 22, 2017, during the LASIC field campaign on Ascension Island. Evaluation data for the W-Band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) value-added product are now available for the ARM Mobile Facility deployment to Ascension…

  • QCRAD Value-Added Data Product Updates Available

    Level 2 (c2/s2) data for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) have now been processed at all Atmospheric Radiation Measurement (ARM) user facility fixed sites through summer 2017. These sites include the Southern Great Plains central and extended facilities, Barrow (known officially as Utqiaġvik) and Oliktok Point, Alaska, and…

  • LASSO Alpha 2 Supplement Includes 2015 Case Dates

    Plots from the Alpha 2 supplement show observed versus simulated cloud fraction for simulation number 13 on June 6, 2015. The plots show observed cloud fraction (top panel) retrieved from the Active Remote Sensing of CLouds (ARSCL) product using the Ka-Band ARM Zenith Radars (KAZRARSCL) product, the simulated cloud fraction (middle panel) based on large-eddy…

  • Quality Controlled Eddy Correlation Flux Measurement Data Now Updated for SGP

    The protocol for the QCECOR VAP workflow is shown here. Two more years of data have been processed for the Quality Controlled Eddy Correlation (QCECOR) value-added product (VAP). This VAP provides improved surface turbulence flux measurements to the ARM user community. Data now extend from 2003 to October 2017 for all systems at the Southern Great…

  • KASACR Data Quality Masks Value-Added Product Now Available in Evaluation

    Evaluation data for the Ka-Band Scanning ARM Cloud Radar (KASACR) Data Quality Masks are now available from the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign conducted in June and July 2017. The specific dates covered in this data set are June 18 through July 31, 2017. Data quality masks help…

  • Aerosol Optical Properties VAP Now Available

    The first plot shows the aerosol extensive property of light absorption for nominally “red,” “green,” and “blue” light over a two-week period at Ascension Island. The second plot shows the wavelength dependence of aerosol absorption—an intensive property—which describes the nature rather than the abundance of the absorption. The Aerosol Optical Properties (AOP) value-added product (VAP)…

  • New Version of Python ARM Radar Toolkit Available

    Plots of differential reflectivity (top) and reflectivity factor are shown from the X-Band Scanning ARM Precipitation Radar on Graciosa Island in the Azores. Py-ART has a new experimental reader allowing the new format to be read. The latest version of the Python ARM Radar Toolkit (Py-ART), an open-source architecture for interacting with radar data in…

  • ARM Best Estimate 2D Data Sets Available for 2004 to 2010

    ARMBE2DGRID surface sensible (left) and latent (right) heat fluxes are shown from July 2010. Data sets for the years 2004 to 2010 for ARM Best Estimate 2-dimensional (2D) Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) are available in the ARM Data Center. The primary goal of these two data sets is to…

  • Microwave Radiometer Retrieval Data Available for LASIC Field Campaign

    Precipitable water vapor (PWV) and liquid water path (LWP) data are seen for the main ARM Mobile Facility site on Ascension Island on July 22, 2017. The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has now been processed for the full Layered Atlantic Smoke Interactions with Clouds (LASIC) field campaign. This VAP gathers column precipitable…
