  • New Merged Product Integrates G-1 Flight Data

    Aerosol concentration data from the G-1 ultrafine condensation particle counter are shown for an approximately three-hour flight on December 8, 2018, near Córdoba, Argentina, during the CACTI campaign. Image is from Krista Gaustad, Pacific Northwest National Laboratory. From 2010 until its final science mission in 2018, the Gulfstream-159 (G-1) aircraft served as the Atmospheric Radiation…

  • Cloud Condensation Nuclei Vertical Profile Data Product Updated

    This sample plot from ARM’s Southern Great Plains atmospheric observatory shows the retrieved number concentration of cloud condensation nuclei at 0.4% supersaturation for September 22, 2016. A new version of the Retrieved Number concentration of Cloud Condensation Nuclei value-added product (RNCCN VAP) is now available for evaluation. This VAP provides the vertical distribution of cloud…

  • New Aerosol Data Product Released From HI-SCALE Campaign

    Sample plots show the time series (upper) and averaged size distributions (lower) for aerosols measured over the Southern Great Plains atmospheric observatory on one research flight. BEASD refers to the best-estimate aerosol size distribution. Aircraft altitude is traced on the upper panel with a black dashed line (mark log scale). “Straight and level” flight legs…
