Exploiting ground-based optical sensing technologies for volcanic gas surveillance
volcano monitoring volcano plumes IR and UV spectoscopy
2015/9/15
Measurements of volcanic gas composition and flux are crucial to probing and understanding a range of magmatic,
hydrothermal and atmospheric interactions. The value of optical remote sensing methods ...
Optical measurements of atmospheric particles from airborne platforms:in situ and remote sensing instruments for balloons and aircrafts
remote sensing LIDAR backscattersonde aerosol
2015/9/7
Multiwavelength laser backscattersondes (MAS) have been widely used from a variety of airborne platforms for in situ measurements of optical properties of clouds and atmospheric particulate as well as...
Mt.Etna aerosol optical thickness from MIVIS images
remote sensing aerosol optical thickness Mt. Etna volcano MIVIS 6S
2015/9/7
This work focuses on the evaluation of Aerosol Optical Thickness (AOT) in Mt. Etna volcano area starting from the analysis of MIVIS VIS images. MIVIS images and ancillary data (atmospheric profiles, p...
Optical method for measuring bed topography and flow depth in an experimental flume
Optical method bed topography flow depth experimental flume
2014/12/31
We describe an optical method known as moiré for acquiring quasi-simultaneous measurements of bed topography and flow depth in laboratory experiments. The moiré method is based on projecting a fringe ...
CONTRAST INVARIANT AND AFFINE SUB-PIXEL OPTICAL FLOW
Optical flow affine and contrast invariant remote sensing Digital Elevation Model (DEM) sub-pixel disparity
2014/4/15
This paper presents the Contrast Invariant and Affine Optical Flow(CIAO), a dense area-based sub-pixel image matching algorithm.CIAO does not force the estimated disparity field between two images to ...

Aerosol optical depth Vertical extinction profile CALPSO/CALIOP
2016/3/25
The vertical distributions and optical properties of aerosols over Shanghai were analyzed using data from ground-based
observation, space remote sensing and trajectories. Measurements of spectral aer...
Deformation during the 1975–1984 Krafla rifting crisis, NE Iceland, measured from historical optical imagery
Krafla rifting crisis IN Iceland measured historical optical imagery
2014/4/15
We measure the displacement field resulting from the 1975–1984 Krafla rifting crisis, NE Iceland, using optical image correlation. Images are processed using the COSI-Corr software package. Surface ex...
