Observations of aerosol-cloud interactions with varying vertical separation between biomass-burning aerosols and stratocumulus clouds over the South-East Atlantic
… In addition, the median liquid water content (LWC) near cloud base was 0.06 g m-3 lower while similar LWC was sampled within cloud and near cloud top the LWC was 0.08 g m-3 higher. Inhomogeneous mixing near cloud top led to a decrease in the total number concentration and LWC by up to 28% and …

Hydraulic modeling and performance evaluation of low water crossings in Illinois
… that need to be replaced. Low water crossings (LWCs) have been used as an economical alternative to culverts and bridges, designed without overtopping, on low-volume roads where there is a low number of floods. The lack of design guidance has posed difficulty for county engineers in Illinois in …

The dependence of arctic mixed phase stratus ice cloud microphysics on aerosol concentration using observations acquired during ISDAC and M-PACE
… SDs, liquid effective radius rel, and liquid (LWC) and ice water content (IWC). For the ISDAC cases, the cloud properties were then examined as a function of ambient accumulation mode aerosol concentrations Na above and below the cloud measured by a Passive Cavity Aerosol Spectrometer Probe …

Microphysical Mechanisms in Stratiform Precipitation as Observed in OLYMPEX
… concentrations, and liquid water content (LWC). However, the dual-polarization radar and in-situ aircraft data indicated certain differences from the generally accepted model. Aircraft particle sampling showed large- and medium-sized ice particles within a secondary maximum in reflectivity …

Optical remote sensing for agriculture monitoring: a quantitative assessment under local conditions
… three crop biophysical parameters (LAI, LCC, LWC) from Sentinel-2 data for six major crop types cultivated in Czechia (winter and spring cereals, oil rapeseed, fodder crops, corn, and sugar beet), b) the proposal for a harmonized LAI calculation method utilizing images from both Sentinel-2 and …

Investigating the impacts of entrainment on nucleation scavenging of black carbon particles through particle-resolved simulations
… (CDNC) and the liquid water content (LWC) according to the amount of entrainment. In Case 2, the CDNC and LWC followed the same pattern as Case 1 when using T2 profiles, while the CDNC was higher than the no entrainment case for the scenarios with T1 profiles. The size distribution …

Characterization and modeling of aerosol-cloud interactions toward the improvement of rainfall estimation in high mountains
… conditions, and the spatial variability of the LWC, CDNC, and CDSD was characterized. Simulations show large differences between the region around the updraft and regions of entrainment located at cloud edges and preferred locations. The interplay of environmental wind and cloud circulations …

Behaviour of lightweight concrete beams strengthened with carbon fibre reinforced polymer in shear
… and the concrete. However, lightweight concrete (LWC) beams, which use Pulverised Fuel Ash (Lytag) instead of normal aggregates, retrofitted to increase shear capacity with epoxy bonded FRP have not been studied comprehensively to understand the characteristics of FRP/ lightweight concrete joining …

Simulations of droplet dispersion in the wakes of cylinders and icing tunnel spray bars
… to obtain a nearly uniform liquid water content (LWC) distribution in the test section (to recreate atmospheric icing conditions).. For this goal, droplets are diffused by the mean and turbulent flow generated from the nozzle air jets, from the upstream spray bars, and from the vertical strut …

Quantifying the Environmental Performance of a Stream Habitat Improvement Project
… utilizing a “franken-log” design (a ballasted LWC configuration with a rootwad fastened to the downstream end of a log) in LWCs which led to favorable TDI change. This study concluded that LCA could be a valuable tool for monitoring SHI and river restoration projects and that further research …
