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

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

In (b), the topography is shaded in gray. In June 2007, an observation campaign on sea breezes was conducted over Sendai Airport. In addition to conventional surface observations, intensive observations from ground-based NICT and Electronic Navigation Research Institute (ENRI) Doppler lidars ( Komatsubara and Kaku 2005 ) and Japan

central Europe. Studying complex terrain is necessary to allow a wider range of opportunities for LES in real-world micrometeorological investigations. The simulated periods contain the transitions from nocturnal to daytime boundary layers and vice versa. The model results are evaluated against measurements of wind profiles using a triple Doppler-lidar setup. The first objective of this study is to analyze and evaluate model setups to achieve a stable model run in WRF-LES when using realistic boundary

lidars aboard the UWKA. These observations are used in an effort to understand the lifting mechanism and effective source level for CI in LC regions. Specifically, we use the airborne lidar data to determine the actual vertical displacement for parcels at all possible source levels and compare this against the vertical distance to the parcel’s LFC. The UWKA completed a total of 20 transects across three convergent boundary zones leading this MCS. The first zone, referred to as Region I ( Fig. 2 ), is
