the DAWN lidar, dropsonde, and satellite observations of the barrier wind observed on 21 May 2015 from approximately 1900 to 2200 UTC. Our focus is to use these observations to evaluate how well high-resolution regional simulations with the Weather Research and Forecasting (WRF) Model can reproduce the observed features with different horizontal and vertical resolutions and with two different boundary layer parameterizations. As such, we will not focus on diagnosing the dynamics that create the

their influence on high-impact weather downstream ( Schäfler et al. 2018 ). For the first time, an established Doppler wind lidar payload on board the research aircraft DLR Falcon performed dedicated observations of the jet stream winds providing both high vertical and horizontal resolution, which is not available from other observational sources. Additionally, the wind lidar dataset is supplemented by dropsonde and ground-based wind profiler observations to provide a wider coverage and to

1. Introduction Assessment and improvement of numerical weather prediction (NWP) model skill require accurate profile measurements of meteorological quantities, including wind. Here we use high-precision, high-resolution wind profiles measured by shipborne Doppler lidar during a monthlong research cruise to evaluate the performance of two modeling systems in the marine atmosphere over the Gulf of Maine, an especially difficult environment in which to obtain such measurements. The focus of this

) sampled the collision between the cold front and outflow boundary, around 0220 UTC. The airborne lidars provide information about the vertical structure of WVMR, LSR, and virtual potential temperature θ υ ( Figs. 7a–c ). The profiling observations show 850-m-deep warmer, moister air (~15 g kg −1 of WVMR below 1.4 km MSL, Fig. 7a ) moving southward behind the cold front approaching the MCS. At the same time, cooler, drier (~8 g kg −1 ) outflow from the parent MCS flowed northward. The MP1

along the boundary. These observations detail the vertical structure of the frontal/outflow boundary, and document lofting sufficient for the initiation of new convective cells that sustain the MCS. A secondary objective is to illustrate how vertical transects of temperature and humidity from an airborne Raman lidar can be used as a novel source of model validation: model validations traditionally have focused on radar reflectivity patterns (i.e., the effect, the resulting precipitation), rather

, and NLLJs. Primary data sources for NLLJ cases were the boundary layer profiles measured by mobile and fixed PECAN Integrated Sounding Arrays (PISAs). These datasets included profiles of dynamic and thermodynamic parameters obtained at high temporal and vertical resolution using Doppler lidars, Atmospheric Emitted Radiance Interferometers (AERIs), radar wind profilers, radiosondes, and microwave radiometers (MWRs), providing observations to describe the SBL and NLLJ evolution. There were four

. 2019 ; Olson et al. 2019b ). For this paper, in addition to the lidars we used a limited set of instrumentation, including NWS airport-site observations and rawinsonde data that would be available to operational forecasters. To document the primary diurnal solar forcing for these flows, its horizontal variability, and the ability of HRRR to reproduce it, sites measuring surface radiation were located at three Oregon locations: Condon, Wasco, and Rufus. Data from a similar fourth site at Eugene
