  • ARM Rolls Out New Products for Determining Boundary-Layer Height

    Plots from top to bottom show micropulse lidar (MPL) backscatter; ceilometer (CEIL) backscatter; Doppler lidar (DL) vertical air motion variance; and estimates of planetary boundary-layer height (PBLHT) derived from MPL, CEIL, DL, and sonde measurements at ARM’s Southern Great Plains Central Facility on June 28, 2017. The structure and depth of the planetary boundary layer…

  • Value-Added Product Estimates Planetary Boundary-Layer Height from Radiosondes

    Example quicklook plot from the VAP showing the sub-sampled potential temperature (black) and potential temperature lapse rate (red) from a single radiosonde along with the estimates of PBL height from the three methods. The planetary boundary-layer (PBL) height (or mixing-layer depth) can vary significantly with time due to a number of factors including large-scale dynamics,…
