Combined use of SEVIRI and MODIS for detecting, measuring, and monitoring active lava flows at erupting volcanoes

Multispectral data acquired by Spinning Enhanced Visible and InfraRed Imager (SEVIRI) onboard the geostationary platform Meteosat Second Generation (MSG2), located at 0◦ longitude, were analyzed to assess the payload suitability for quantitative volcano monitoring. In times of good infrared transparency of the troposphere, SEVIRI data proved particularly suited to detect the onset of effusive eruptions and tomonitor the related lava flows with 15-min refresh rates. After development of a code allowing for fast automated processing of the 96 data streams downlinked daily by MSG2, thorough monitoring tests were carried out on the 2007 eruptions of Stromboli (Aeolian Islands, Italy) and Piton de la Fournaise (Reunion Island, France). The results in radiant flux and effusion rate provided by use of thermal, mid-, and short infrared bands of SEVIRI were validated by exploiting simultaneous MODIS overpasses by Terra and Aqua, up to four times daily

Spaceborne monitoring 2000-2005 of the Pu'u `O'o-Kupaianaha (Hawaii) eruption by synergetic merge of multispectral payloads ASTER and MODIS

The spaceborne thermal monitoring of the great eruption of Pu’u ‘O’o-Kupaianaha in Hawaii (1987 to present) was attempted, integrating high-resolution SWIR–TIR and lowresolution MIR–TIR observations. Data acquired by multispectral payloads ASTER and MODIS onboard spacecraft Terra, and MODIS onboard Aqua, were processed behind real time by the use of computing routines “MyVOL” and “MyMOD” based on assessed theory and designed for real-time operations. The process was tested against the 2000–2005 eruptive history, both in geometry and volume dynamics of the lava flow. Here, instant lava effusion rates obtained from approximately 1800 cloud-free (over a total > 3000) day-/nighttime MODIS scenes and 12 cloud-free (over a total of 30) nighttime ASTER scenes are compared with each other and with volcanological ground truth composed of gas (SO2)- and electromagnetic potential (very low frequency)-derived eruption rates. Remote-sensed eruption rates are consistent with ground truth from approximately 1 m3/s up to the peak effusion rates of 1.2–1.3 million m3/day observed in 2005

Synergetic exploitation of meteorological geostationary payloads «SEVIRI» and «JAMI» for quantitative, real-time, global volcano monitoring

Very low-spatial, very high-temporal resolution multispectral data acquired 2006-2008 by geostationary payloads SEVIRI onboard MSG-1 and MSG-2 orbiting at 0°, and JAMI-Imager onboard MTSAT-1R orbiting at 140°E, were analyzed for feasibility and road tests of quantitative, multi-payload volcano monitoring at high refresh rates. We merged and adapted to the East Asia eruptive scenarios two processing methods developed recently for multi-payload, volcano monitoring on Europe and Africa. Monitoring focused on very high-temperature surface features, involving active lava flows and dome forming, in the light of the the next ceasing of moderate resolution MIR-TIR observations by MODIS and its four daily revisits worldwide. Plans for mantaining and/or implementing the current constellations of meteorological satellites worldwide, conversely, are financially and technically established to cover the next decade

Maximizing the detection and mapping of minimal area burn scars with a multi-payload multi-method automated approach: Application to summer fire seasons in Italy

Two multitemporal techniques based on the consecutive analysis of multispectral data ranging from high-temporal to high-spatial resolution, were implemented into a remote-sensing system dedicated to the quantitative monitoring of wildfires in the Mediterranean Region, operating at low-to-nil supervision levels. The system covers the whole fire remote sensing chain, from accurate hot-spot detection and location to high resolution mapping of burn scars. It operates on strong multi-payload basis, as the first part of the processing chain acts on data acquired by the multispectral geostationary payload SEVIRI, whereas the second was designed to operate switching between data acquired by LEO high resolution payloads TM, ETM+, ASTER, HRVIR and LISS 3, as a function of availability and content. © 2010 IEEE

SEVIRI onboard Meteosat Second Generation, and the quantitative monitoring of effusive volcanoes in Europe and Africa

The spectral and radiometric performance of payload SEVIRI onboard the geostationary platform MSG-2, make its data particularly well suited not only to the detection of the onset of volcanic activity, but also to the measurement of thermal radiant fluxes and eruption rates. Thorough testing was carried out on two volcanoes - Stromboli (Aeolian Islands, Southern Italy) and Piton de la Fournaise (Réunion Island, northwestern Indian Ocean) - that mostly give rise to short-lived lava flows. Aimed to comply with the outstandingly high acquisition rate, we developed an ad-hoc code to automatically detect volcanic hot-spots, measure radiant fluxes, and derive lava volume effusion rates within the 15-minute interval between two SEVIRI data streams. © 2008 IEEE

SIGRI - An integrated system for detecting, monitoring, characterizing forest fires and assessing damage by LEO-GEO data

Forest fires are in the focus of the SIGRI pilot project (Integrated System for Fire Risk Management) funded by the italian Space Agency (ASI). The project, started late in November 2008. It is due for completion by end-2011. The EO part of the project is centred on (1) SAR borne observation in the X, C and the L-bands, from ASI and ESA platforms Cosmo-Skymed and Envisat; (2) on TIR/MIR/SWIR/NIR - and Red, where appropriate - observation by opto-electronic payloads operating at all spatial resolutions from 2006 onwards (SEVIRI,MODIS,HRVIR,HRG,TM, ASTER, LISS-III) and (3) upon SAR very high resolution (Cosmo SkyMed) and V-NIR observation by new commercial or dual-use satellites. The system, of which the appointed user is the Italian Department of Civil Protection (DPC), is expected to deal at once with law enforcement (burn scar mapping), preparedness (risk mapping and urban interface fire contingency planning) and operational issues (fire detection and propagation prediction). It will be demonstrated in three operational theaters (northern Italy - Liguria, southern Italy - Calabria, and the island of Sardinia), all characterized by high frequency of occurrence of fires, but greatly differing in terms of fires style
