  • 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…

  • 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)…

  • Broadband Irradiance VAPs Now Running at New SGP Extended Facilities

    Data plots are shown for extended facilities E39, E40, and E41 located near Lamont, Oklahoma, for the best-estimate total downwelling shortwave irradiance from QCRAD. Two value-added products (VAPs)—Data Quality Assessment for ARM Radiation Data (QCRAD) and Radiative Flux Analysis (RADFLUX)—are now running at the new extended facilities at the ARM Climate Research Facility’s Southern Great…

  • Continuous Large-Scale Forcing Data Now Available for Cloud Modeling From Southern Great Plains

    The seasonal cycle of Southern Great Plains domain-averaged latent heat (LH) and sensible heat (SH) fluxes is shown by using QCECOR-only (QCECOR), BAEBBR-only (BAEBBR), and both QCECOR and BAEBBR data (merged) averaged from 2004-2015, and the impact to the derived large-scale vertical velocity (omega). Version 2 of the continuous forcing value-added product uses the merged…

  • Version 2 of the Continuous Large-Scale Forcing Data Now Available

    Sample plots are shown here from the Southern Great Plains domain-averaged precipitation measurements from Arkansas-Red Basin River Forecast Center and the corresponding vertical velocity based on variational analysis for June 2015. Updated November 2017: Data are now available for the Southern Great Plains atmospheric observatory for the year 2015. The data sets are in netCDF format.…

  • Two New Data Products Available from the Radar Wind Profiler

    Time-height images are shown here of the wind speed at a uniform 10-minute and 50-meter resolution from the radar wind profilers, part of the instrumentation at four observing facilities at the Southern Great Plains megasite. The facility name is shown in the top left corner in each panel. The ceilometer-recorded first cloud base height (red)…

  • New Release of Radar CFAD Data Product for ARM Radar Simulator

    Measured radar reflectivity (top) and the calculated radar CFAD (bottom) are displayed for May 16, 2009. Updated: Newly released data are now included from the Southern Great Plains, North Slope of Alaska, and Tropical Western Pacific atmospheric observatories from 2011 to 2013. Previous radar CFAD data (nsaradarcfadC1.c1) for the period between 2006 and 2010 from the…

  • Oklahoma Mesonet Soil Moisture Product Available for Evaluation

    1998 Volumetric Water Content for the station BUTL in the Oklahoma Mesonet for comparison to the Illston 2008 paper. While the relative temporal behavior is replicated, the absolute volumetric water content with the new coefficients derived by the Oklahoma Mesonet (Scott 2013) is significantly lower than before. For example, it is 35% at the 5-cm…

  • 2D ARM Best Estimate Data Sets Updated to Include QCECOR

    Surface latent (left) and sensible (right) heat fluxes (units are in W/m2) are shown here for ARMBESTNS in July 2012. The data source is QCECOR. Different sites are color-coded. Updated: Data are now available for the Southern Great Plains atmospheric observatory for the years 2013 and 2014. The ARM Best Estimate 2-dimensional Gridded Surface (ARMBE2DGRID) and…

  • MWRRET Version 2 Evaluation Data Available for Southern Great Plains

    Data from the 3-channel microwave radiometer at the Southern Great Plains site are shown here.The optimal estimation retrieval of liquid water path (LWP) and precipitable water vapor (PWV) have now been applied to the new 3-channel microwave radiometer at Southern Great Plains (SGP). Data for 2015 are now available as an evaluation product, called the…
