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...
DEVELOPMENT OF A TIME-DEPENDENT 3-PARAMETER HELMERT DATUM TRANSFORMATION MODEL: A CASE STUDY FOR MALAYSIA

2016/10/14
This paper aims to develop a time-dependent 3-parameter Helmert datum transformation model for Malaysia as a proposed solution to the current non-geocentric issue of the Geocentric Datum of Malaysia 2...
MIRTO: a prototype for real-time ionospheric imaging over the Mediterranean area
ionosphere real-time imaging
2015/9/2
MIRTO (Mediterranean Ionosphere with Real-time TOmography) is a collaborative project between Istituto
Nazionale di Geofisica (INGV) of Rome, the University of Bath (U.K.) and the Istituto Fisica App...
Can the Earth’s harmonic spectrum be derived directly from the stochastic inversion of global travel-time data?
Earthquake GPS Historical seismology Ionosphere Irpinia
2015/8/18
A set of seismic observations which all sample the same structure in the same way should have zero variance. This is naturally the case if all sources are in the same place, and the data are recorded ...
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 ...

Orbital effects the time-dependent component the Pioneer anomaly
2011/8/17
Abstract: We work out the impact that the recently determined time-dependent component of the Pioneer anomalous acceleration may have on the orbital motions of some planets of the solar system in the ...
Characterization of Valley Winter Woodsmoke Concentrations in Northern NY Using Highly Time-Resolved Measurements
Aethalometer Nephelometer Spatial variability Mobile measurements Outdoor wood boilers, Woodsmoke
2016/3/28
The increasing popularity of wood fired heating appliances in cold winter climates has focused attention on assessment of
woodsmoke exposures. Pollution from residential wood combustion (RWC) is a ma...
