Visualization of disaster dispersion prediction enables decision makers and civilian to prepare disaster and to reduce the damage by showing the realistic simulation results. With advances of GIS tech...
Volcanic Ash Retrieval Using a New Geostationary Satellite
Volcanic ash aerosol geostationary satellite GK-2A MODIS
2015/7/27
The paper presents currently developing method of volcanic ash detection and retrieval for the Geostationary Korea Multi-Purpose Satellite (GK-2A). With the launch of GK-2A, aerosol remote sensing inc...
Annex to:Volcanic Ash Cloud Observation using Ground-based Ka-band Radar and Near-Infrared Lidar Ceilometer during the Eyjafjallajökull eruption

Volcanic ash plumes are formed during explosive volcanic eruptions. After advection over several thousands of kilometers, volcanic ash particles are highly fragmented, dispersed and aged with micron- ...
Improvements on Near Real Time Detection of Volcanic Ash Emissions for Emergency Monitoring with Limited Satellite Bands
Volcanic ash disperion monitoring satellite dispersion model
2015/8/18
Quantifying volcanic ash emissions syneruptively is an important task for the global aviation community. However, due to the near real time nature of volcano monitoring, many parameters important for ...
Volcanic Ash Cloud Observation using Ground-based Ka-band Radar and Near-Infrared Lidar Ceilometer during the Eyjafjallajökull eruption
Volcanic eruptions radar lidar
2015/8/18
Active remote sensing techniques can probe volcanic ash plumes, but their sensitivity at a given distance depends upon the sensor transmitted power, wavelength and polarization capability. Building on...
Volcanic Ash and SO2 retrievals using synthetic MODIS TIR data:comparison between inversion procedures and sensitivity analysis
Volcanic Ash SO2 retrievals synthetic MODIS TIR data
2015/8/18
In this work the volcanic ash and SO2 retrievals obtained by applying three different procedures (LUT - Look Up Table, NN - Neural Network and VPR - Volcanic Plume Removal) on MODIS Thermal InfraRed (...
Dissolution of Humic Substances from Highly Humic Volcanic Ash Soil as Affected by Anionic Surfactant, Electrolyte Concentration and pH
Surfactant Humic Substances Electrolyte Volcanic ash Aoil pH
2013/3/11
Dissolved humic substances separated from soils play an important role in the material cycle because they adsorb nutrients and contaminants and move with water. This study was conducted to investigate...
Volcanic ash as fertiliser for the surface ocean
Volcanic ash fertiliser the surface ocean
2010/8/12
Iron is a key limiting micro-nutrient for marine primary productivity. It can be supplied to the ocean by atmospheric dust deposition. Volcanic ash deposition into the ocean represents another externa...
Shutting down air travel in response to the volcanic activity in Iceland might seem drastic, but it is a measured response to the hard-to-measure threat caused by the ash plume that shot high into Ear...
Use of immobile trace elements for the correlation of Telychian bentonites on Saaremaa Island,Estonia,and mapping of volcanic ash clouds

2009/9/9
There is an increasing interest in the extraction of DNA from soil, since molecular techniques facilitate the analysis of the microbial community including unculturable microorganisms. Though various ...
Evaluation of rainfall infiltration characteristics in a volcanic ash soil by time domain reflectometry method
Time domain reflectometry rainfall intensity volcanic-ash soil
2009/6/8
Time domain reflectometry (TDR) was used to monitor soil water conditions and to evaluate infiltration characteristics associated with rainfall into a volcanic-ash soil (Hydric Hapludand) with a low ...
Retrieval of SO2 from thermal infrared satellite measurements:correction procedures for the effects of volcanic ash
SO2 thermal infrared satellite measurements correction procedures volcanic ash
2010/2/8
The simultaneous presence of SO2 and ash in a volcanic plume can lead to a significant error in the SO2 column abundance retrieval when multispectral Thermal InfraRed (TIR) data are used. The ash part...
Response of cabbage to depth of transplanting, soil amendment and water stress on a Japanese volcanic ash soil
Animal manure chemical fertilizer cabbage growth transplants
2009/3/3
Transplants growth may be reduced by environmental factors when appropriate cultural practices are not used. We studied the response of cabbage to depth of transplanting (DT), soil amendment (SA...
