  • Microwave Radiometer Retrieval Product Processed for SGP Central Facility

    This Microwave Radiometer Retrievals (MWRRET) quicklook image provides information from the Southern Great Plains Central Facility on August 10, 2019. 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); and retrieved liquid water…

  • Microwave Radiometer Retrieval Data Available for 3 ARM Campaigns

    The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition used microwave radiometers (2-channel on the left and 3-channel on the right) to measure water vapor and liquid molecules in the atmosphere. The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has been released for three recent Atmospheric Radiation Measurement (ARM) user facility field…

  • Microwave Radiometer Retrievals VAP Available for New Set of ARM Campaigns

    This Microwave Radiometer Retrievals (MWRRET) quicklook image provides information from the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign on April 27, 2019. The image shows (a) observed brightness temperatures at 23.8 GHz (blue) and 31.4 GHz (red); (b) retrieved precipitable water vapor from the physical method (blue) and statistical method (green); and (c)…

  • Cloud Microphysics VAP Evaluation Data Available for MC3E Field Campaign

    Cloud microphysical properties affect cloud radiative heating, precipitation formation, and aerosol-cloud interactions, among other important atmospheric processes. A value-added product (VAP) that calculates cloud microphysical properties now provides evaluation data for the 2011 Midlatitude Continental Convective Clouds Experiment (MC3E) in Oklahoma. The Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) provides continuous, high time resolution profiles of…

  • Cloud Microphysics VAP Evaluation Data Available for LASIC Field Campaign

    Cloud microphysical properties affect cloud radiative heating, precipitation formation, and aerosol-cloud interactions, among other important atmospheric processes. The first field campaign data are now available from a value-added product (VAP) that builds upon the Atmospheric Radiation Measurement (ARM) user facility’s historical Continuous Baseline Microphysical Retrieval (MICROBASE) VAP. The Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) provides…

  • New Microwave Radiometer Retrievals VAP Data Available for Several ARM Campaigns and Sites

    Microwave radiometers, such as this one at ARM’s North Slope of Alaska atmospheric observatory, provide time-series measurements of column-integrated amounts of water vapor and liquid water. The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has been processed for the following Atmospheric Radiation Measurement (ARM) user facility field campaigns and measurement sites: the ARM North Slope…

  • 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…

  • Microwave Radiometer Retrieval Data Available for AMF Sites

    An example plot from the MWRRET VAP for 11/9/2007 at Black Forest, Germany: (top) Brightness temperatures measured by the microwave radiometer (MWR). Orange and blue lines indicate potential measurement spikes due to precipitation; (middle) retrieved precipitable water vapor from the new physical method (blue) and the original statistical method (green); (bottom) retrieved liquid water path…

  • It’s Official Now—Cloud Microphysical Properties Value-Added Product Changes Status

    The Continuous Baseline Microphysical Retrieval (MICROBASE) value-added product (VAP) has been released as an official ARM VAP. Data from April 1998 through December 2009 are now available for the Southern Great Plains, North Slope of Alaska, and Tropical Western Pacific sites. Historical updates will be provided whenever additional data become available.This sample quicklook plot shows…
