  • Radiative Flux Analysis Data Reprocessed for SGP Broadband Radiometer Station

    This plot shows reprocessed irradiance and albedo—surface reflectivity—from the Radiative Flux Analysis (RADFLUXANAL) value-added product for the broadband radiometer station at ARM’s Southern Great Plains atmospheric observatory from April 22 to 23, 2019. All historical Radiative Flux Analysis value-added product (RADFLUXANAL VAP) data for the broadband radiometer station (BRS) at the Southern Great Plains atmospheric…

  • 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…

  • Updated Surface Spectral Albedo Data Released

    This example quicklook from the SURFSPECALB value-added product shows the estimated spectral albedo for the 10- and 25-meter towers at ARM’s Southern Great Plains atmospheric observatory on June 2, 2016. On that date, the surface type for both towers was all vegetation. Updated data from the Surface Spectral Albedo value-added product (SURFSPECALB VAP) are available…

  • Updated Tower Water-Vapor Mixing Ratio Product Now Available

    An updated version of the Tower Water-Vapor Mixing Ratio value-added product (TWRMR VAP) is now available for use. This VAP calculates water vapor mixing ratios at the 25- and 60-meter levels of the meteorological tower at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains (SGP) Central Facility. TWRMR also provides best-estimate temperature, relative…

  • Radiation Data Quality VAP Data Reprocessed for SGP Broadband Radiometer Station

    The broadband radiometer station provides continuous measurements of broadband shortwave (solar) and longwave (infrared) irradiances for downwelling components. An end-to-end reprocessing of data from the Data Quality Assessment for ARM Radiation Data value-added product (QCRAD VAP) is complete for the broadband radiometer station (BRS) at the Southern Great Plains (SGP) atmospheric observatory. All historical data…

  • 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…

  • ARM Evaluation Product Delivers 4-Dimensional Map of Cloudiness

    This sample plot from the COGS value-added product shows a heat map of cloud depth at 21:29:40 UTC (Coordinated Universal Time) on August 4, 2019, at ARM’s Southern Great Plains atmospheric observatory. A new value-added product (VAP) called Clouds Optically Gridded by Stereo (COGS) provides a four-dimensional (4D) map of cloudiness. This map is generated…

  • Aerosol Hygroscopicity Kappa Data Product Available for Evaluation

    Sample plots from ARM’s Southern Great Plains atmospheric observatory show kappa values within critical diameter-supersaturation field space, top, and a time series of kappa, bottom. A new value-added product (VAP) from the Atmospheric Radiation Measurement (ARM) user facility calculates the hygroscopic properties of measured aerosol particles. Hygroscopicity is the ability of a particle to take…

  • Updated ARM Best Estimate Data Available for Southern Great Plains

    The plots show ARMBEATM relative humidity, top, and surface precipitation, bottom, from May 31 to August 28, 2018, at ARM’s Southern Great Plains (SGP) atmospheric observatory. The Atmospheric Radiation Measurement (ARM) user facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the evaluation of global earth system models. Two…

  • New Journal Article Highlights ARM Aerosol Data Set

    Value-added product leverages long-term Southern Great Plains data The Quality Control Aerosol Optical Depth (QCAOD) value-added product combines individual aerosol optical depth records provided by the Cimel sunphotometer (left), multifilter rotating shadowband radiometers (middle), and normal incidence multifilter radiometer (right). A March 2021 article in the journal Scientific Data presents two decades of aerosol data…
