Modeling and Lidar Study on Ozone Over the Chesapeake Bay During OWLETS-2

Autor: Yang Zhifeng, Delgado Ruben, Demoz Belay, Sullivan John, Gronoff Guillaume, Berkoff Timothy

Publikováno v: EPJ Web of Conferences, Vol 237, p 03015 (2020)

This study focuses on the distribution of ozone (O3) concentration near the Chesapeake Bay, USA (hereafter CB) by integrating observations and model simulations. The motivation of this work is to understand reasons causing the horizontal and vertical

Lidar Observations Versus Forecast of Water Vapor Transport

Autor: Carroll Brian, Demoz Belay, Delgado Ruben

Publikováno v: EPJ Web of Conferences, Vol 237, p 06008 (2020)

Water vapor advection is an important diagnostic parameter for initiation and sustenance of convective systems. This variable has traditionally been explored with balloon soundings or models, but lidar provides a unique opportunity to continuously re

Lidar Profiling In the lower Troposphere: experience from PECAN

Autor: Demoz Belay B., Delgado Ruben, Caroll Brian, Vermeesch Kevin, Whiteman David N., Sakai Ricardo, Tesfay Sium, Cooper Lorenza

Publikováno v: EPJ Web of Conferences, Vol 176, p 10004 (2018)

Results from the PECAN (Plains Elevated Convection at Night) campaign are discussed. In particular, the utility of simple backscatter lidars/ceilometers in quantifying atmospheric dynamics parameters and variables as well as evolution of the lower tr

Mixed layer depths via Doppler lidar during low-level jet events

Autor: Carroll Brian, Demoz Belay, Bonin Timothy, Delgado Ruben

Publikováno v: EPJ Web of Conferences, Vol 176, p 06017 (2018)

A low-level jet (LLJ) is a prominent wind speed peak in the lower troposphere. Nocturnal LLJs have been shown to transport and mix atmospheric constituents from the residual layer down to the surface, breaching quiescent nocturnal conditions due to h

Estimate of rain evaporation rates from dual-wavelength lidar measurements: comparison against a model analytical solution

Autor: Lolli Simone, Di Girolamo Paolo, Demoz Belay, Li Xiaowen, Welton Ellsworth J.

Publikováno v: EPJ Web of Conferences, Vol 176, p 04002 (2018)

Rain evaporation significantly contributes to moisture and heat cloud budgets. In this paper, we illustrate an approach to estimate the median volume raindrop diameter and the rain evaporation rate profiles from dual-wavelength lidar measurements. Th
