  • 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…

  • MICROARSCL Evaluation Data Released: Harnessing the Power of Radar Doppler Spectra

    Four of the roughly 30 variables provided by MICROARSCL are shown here for a day in Barrow, Alaska. Since 2004, the ARM Climate Research Facility has collected continuous recordings of profiling radar Doppler spectra. These recorded spectra offer a powerful means for overcoming the dependency of radar measurements on particle size (proportional to the sixth…

  • New Best Estimate Data Available for WACR-ARSCL

    A data plot from the WACR-ARSCL Reflectivity Best Estimate from Graciosa Island, Azores, is shown for June 27, 2009. New data from the 95 GHz W-band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) value-added product (VAP) (Kollias and Miller, 2007) are now available in the ARM Data Archive. In addition to the WACR data,…

  • Forcing Data for MC3E Updated

    Multi-scale domains for MC3E, with diameters of 300 km, 150 km, and 75 km. The red triangles denote sounding locations. The green diamonds denote the locations of scanning cloud radars. Large-scale forcing data from the Midlatitude Continental Convective Clouds Experiment (MC3E) have been revised based on the recent update to MC3E sounding data for improved…

  • Ceilometer Derived Planetary Boundary Layer Height Datastream Available

    At the 2012 ASR Science Team Meeting, this comparison received positive feedback from researchers. Planetary Boundary Layer (PBL) height data are now being collected at ARM sites and mobile facilities using an enhanced gradient method algorithm from the Vaisala Ceilometers (VCEIL). These data are part of a new datastream available to the ARM and broader…

  • Standards for ARM Data Assure Consistency, Sustainability

    To sustain and enable consistent use and analysis of multiyear data sets by the scientific community, the newly published ARM Data Standards Version 1.0 details the required and recommended standards for ARM data.

  • ARM Data Archive Registered with Elsevier

    Increased visibility via Elsevier’s data repository presents an opportunity to broaden the scientific audience for ARM data. With an ever-increasing need to connect related pieces of information, databases rule the world. As of mid-March, the ARM Data Archive—containing two decades of continuous measurements of clouds, aerosol, precipitation, and radiative energy from ARM sites around the…

  • Ensemble Large-Scale Forcing Data for the MC3E Campaign Available

    This image shows different precipitation rates from the ensemble data set. Ensemble forcing data from the Midlatitude Continental Convective Clouds Experiment (MC3E) were developed by considering uncertainties in precipitation observations using the analysis described in Zhang and Lin [1997] and Zhang et al. [2001]. MC3E was a major ARM field campaign conducted from April to…

  • Derived Wind Profile Data from Doppler Lidar Ready for Review

    Height-time display of wind speed (colors) and direction (arrows) from the Doppler lidar at the Southern Great Plains site for October 4, 2012. Vertically resolved wind measurements are crucial for numerical weather prediction and for modeling pollutant and aerosol transport. The scanning, coherent Doppler lidars operated by the ARM Facility have the capability of providing…

  • New ARM Best Estimate Land Product Contains Critical Soil Quantities for Describing Land Properties

    Soil moisture at the SGP Central Facility site for 1998, mean over five EBBR sensors, measured at 5 centimeters underground. The ARM Best Estimate: Land (ARMBELAND) value-added prduct (VAP) is a subset of the ARM Best Estimate (ARMBE) products designed to support community land-atmospheric research and land model developments. It contains several critical soil quantities…
