RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Fog detection, Radiative Transfer Model SBDART Indo-Gangetic plain Brightness temperature difference threshold Middle Infrared Thermal Infrared
2019/2/28
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...
A meteoroid penetrating the Earth’s atmosphere leaves behind a trail
of dense plasma embedded in the lower E/upper D-region ionosphere. While
radar measurements of meteor trail evolution have been c...
Ion thermal effects on E-region instabilities: 2D kinetic simulations
E-region electrojet Ionospheric irregularities Plasma instabilities
2017/3/22
Radars frequently receive strong returns from naturally occurring plasma density irregularities centered around
100 km altitude in the atmosphere. These E-region ionospheric irregularities occur when...
INFLUENCE OF RIVER BED ELEVATION SURVEY CONFIGURATIONS AND INTERPOLATION METHODS ON THE ACCURACY OF LIDAR DTM-BASED RIVER FLOW SIMULATIONS
LiDAR Digital Terrain Model River Bed Survey Configuration Interpolation Integration Flow Simulation
2016/10/14
In this paper, we investigated how survey configuration and the type of interpolation method can affect the accuracy of river flow simulations that utilize LIDAR DTM integrated with interpolated river...
The use of Monte Carlo simulations for seismic hazard assessment in the U.K.
Seismic hazard Monte Carlo simulation
2015/9/30
The input required for a seismic hazard study using conventional Probabilistic Seismic Hazard assessment (PSHA) methods can also be used for probabilistic analysis of hazard using Monte Carlo simulati...
Inferences on the source mechanisms of the 1930 Irpinia (Southern Italy) earthquake from simulations of the kinematic rupture process
1930 Irpinia earthquake ground motion simulation kinematic source model
2015/9/11
We examine here a number of parameters that define the source of the earthquake that occurred on 23rd July 1930 in Southern Italy (in the Irpinia region). Starting from the source models proposed in d...
