Multistatic Specular Meteor Radar Network in Peru: System Description and Initial Results

open access: yesEarth and Space Science, 2021
The mesosphere and lower thermosphere (MLT) region is dominated globally by dynamics at various scales: planetary waves, tides, gravity waves, and stratified turbulence. The latter two can coexist and be significant at horizontal scales less than 500 km,

Statistical Denoising of Transient Rendering

open access: yesComputer Graphics Forum, EarlyView.
Abstract Transient rendering simulates light in motion, measuring the time of flight from the light source to the camera. However, the stochastic nature of Monte Carlo is aggravated in transient rendering, since samples are now spread along the temporal domain.

2D Piecewise Linear Scalar Fields with Invertible Integral Lines

open access: yesComputer Graphics Forum, EarlyView.
Abstract Integral lines of the gradient flow are standard features in continuously differentiable scalar fields that enjoy some useful properties: They cover the domain densely, do not split, merge, or intersect, and are therefore invertible. For widely used discretizations of scalar fields, the corresponding polygonal approximations of integral lines ...

Retrieval of atmospheric quantities from remote sensing measurements of nightglow emissions in the MLT region

open access: yes, 2020
In the mesosphere and lower thermosphere (MLT) region, atomic oxygen and hydrogen are the most abundant reactive trace species and play crucial roles in the photochemistry and energy budget.

On the relationship between the mesospheric sodium layer and the meteoric input function [PDF]

open access: yesAnnales Geophysicae
This study examines the relationship between the concentration of atmospheric sodium and its meteoric input function (MIF). We use the measurements from the Colorado State University (CSU) and the Andes Lidar Observatory (ALO) lidar instruments with a ...

Study of the Quasi‐5‐Day Wave in the MLT Region by a Meteor Radar Chain [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2018
AbstractAn extensive analysis of quasi 5‐day waves (5DWs) in the mesosphere and lower thermosphere and their responses to a major sudden stratospheric warming (SSW) event (January 2013) are presented. The analysis is based on data conducted from a meteor radar chain in the period from December 2008 to November 2017 and Aura Microwave Limb Sounder ...

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Kelvin-Helmholtz billows and their effects on mean state during gravity wave propagation [PDF]

open access: yesAnnales Geophysicae, 2009
The Kelvin-Helmholtz (KH) billows which appear in the process of gravity wave (GW) propagation are simulated directly by using a compressible nonlinear two-dimensional gravity wave model.
