Polarimetric X-band weather radar measurements in the tropics: radome and rain attenuation correction
(COPERNICUS GESELLSCHAFT MBHGOTTINGEN, 2012)
A polarimetric X-band radar has been deployed during one month (April 2011) for a field campaign in Fortaleza, Brazil, together with three additional laser disdrometers. The disdrometers are capable of measuring the raindrop ...
An energy-based approach to estimate seismic attenuation due to wave-induced fluid flow in heterogeneous poroelastic media
(Wiley Blackwell Publishing, Inc, 2016-11)
Wave-induced fluid flow (WIFF) due to the presence of mesoscopic heterogeneities is considered as one of the main seismic attenuation mechanisms in the shallower parts of the Earth's crust. For this reason, several models ...
Atmospheric correction assessment of SPOT-6 image and its influence on models to estimate water column transparency in tropical reservoir
(2016-10-01)
Remote sensing images have been increasingly used by its ability to collect data from extensive areas in a short time and with relatively low cost. Studies conducted in aquatic environments require great attention in ...
On the attenuation of vibration using a finite periodic array of rods comprised of either symmetric or asymmetric cells
(2021-10-27)
Periodic structures have an important role to play in the reduction of vibration within a targeted frequency range. Much of the literature concerning vibrations in periodic structures involves the description of wave ...
Comparison between two attenuation models and precipitation evaluation with ground validation
(Institute of Electrical and Electronics Engineers, 2017-01)
In this paper we present an algorithm to correctfor attenuation by absorption plus scattering, the horizontalreflectivity factor Zh of a polarimetric radar belonging to theExperimental Station of INTA, located in the town ...
Horizontal attenuated total reflection applied to simultaneous determination of ash and protein contents in commercial wheat flour
(Elsevier Science BvAmsterdamHolanda, 2005)
SVD filtering applied to ground-roll attenuation
(2010)
We present a singular value decomposition (SVD) filtering method for attenuation of the
ground roll. Before the SVD computation, normal move-out (NMO) correction is applied to the seismograms, with the purpose of flattening ...
