IGARSS 2015 - 2015 IEEE International Geoscience and Remote Sensing Symposium

The Geoscience and Remote Sensing Society (GRSS) seeks to advance science and technology in geoscience, remote sensing and related fields using conferences, education and other resources. Its fields of interest are the theory, concepts and techniques of science and engineering as they apply to the remote sensing of the earth, oceans, atmosphere, and space, as well as the processing, interpretation and dissemination of this information.


2008 Second Workshop on Use of Remote Sensing Techniques for Monitoring Volcanoes and Seismogenic Areas (USEReST)

To gather contributions on the experience of different groups (users and technology developers) in order to formulate technical and general requirements for future activities on Earth Observation based services. To provide a platform to exchange experience of integrating Earth Observation (EO) based information with traditional observation methods and models. The workshop will be organized in thematic sessions followed by round table discussions.

Experimental study on shell-strengthening the lightweight pumice aggregates

Lv Xingjun; Cao Mingli 2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011

Natural pumice aggregates have the characteristics of low numerical tube pressure and high water absorption, in this study, the pumice aggregates was reinforced by making shell process with the methods of mixing pumice powder and silica fume into cement, which aimed to solve the problem that it was difficult for the preparation of lightweight concrete of high strength . Through ...


A Robust Multitemporal Satellite Technique for Volcanic Activity Monitoring: Possible Impacts on Volcanic Hazard Mitigation

F. Marchese; G. Malvasi; M. Ciampa; C. Filizzola; N. Pergola; V. Tramutoli 2007 International Workshop on the Analysis of Multi-temporal Remote Sensing Images, 2007

Among the natural hazards, volcanoes represent one of major risk for both population and surrounding infrastructures, causing every year significant economical and environmental damages. Satellite remote sensing, thanks to multispectral data, high observational frequencies and global coverage, represents an important tool for volcanic activity monitoring, especially in remote areas where traditional techniques are generally inadequately applied. A new multitemporal satellite ...


Theoretical Study on Volcanic Plume <formula formulatype="inline"><tex Notation="TeX">$hbox{SO}_{2}$ </tex></formula> and Ash Retrievals Using Ground TIR Camera: Sensitivity Analysis and Retrieval Procedure Developments.

Stefano Corradini; Cecilia Tirelli; Gabriele Gangale; Sergio Pugnaghi; Elisa Carboni IEEE Transactions on Geoscience and Remote Sensing, 2010

In this paper, a sensitivity analysis and procedure development for volcanic- plume sulfur dioxide and ash retrievals using ground thermal infrared camera have been carried out. The semiconductor device camera, considered as a reference, has a spectral range of 8-14 ¿m with noise equivalent temperature difference that is better than 100 mK at 300 K. The camera will be used ...


Ground-based radar remote sensing of explosive volcanic ash eruptions: Numerical models and quantitative applications

F. S. Marzano; S. Marchiotto; S. Barbieri; D. Schneider; C. Textor; G. Giuliani 2008 Second Workshop on Use of Remote Sensing Techniques for Monitoring Volcanoes and Seismogenic Areas, 2008

Microphysical and dynamical features of volcanic clouds, due to Plinian eruptions, can be quantitatively monitored by using ground-based microwave weather radars. In order to illustrate the potential of this microwave active remote sensing technique, the case study of the eruption of Augustine volcano in Alaska in January 2006 is described and analyzed. Volume data, acquired by a NEXRAD WSR-88D S-band ...


Strategies for the optimal classification of volcanic ash granulometry

B. Andò; S. Baglio; V. Marletta 2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015

The ash fall-out following explosion activity of volcanoes like the Mount Etna, represents a serious hazard for the safety of air traffic, causing, in many cases, flight cancellations or temporary closures of the airport with consequently inconvenience for passengers and loss of profit for airlines. Researchers at DIEEI of the University of Catania, in the framework of the SECESTA project ...
