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...
Application of a global nonhydrostatic model with a stretched-grid system to regional aerosol simulations around Japan

2015/3/5
An aerosol-coupled global nonhydrostatic model
with a stretched-grid system has been developed. Circulations over the global and target domains are simulated with
a single model, which includes @...
A coupling alternative to reactive transport simulations for long-term prediction of chemical reactions in heterogeneous CO2 storage systems

<
2015/3/5
Fully coupled, multi-phase reactive transport simulations of CO2 storage systems can be approximated by
a simplified one-way coupling of hydrodynamics and reactive chemistry.
