The Multispectral Instrument (MSI) and the Operational Land Imager (OLI), respectively onboard Sentinel-2A/2B Landsat 8 satellites, thanks to their features especially in terms of spatial/spectral resolution, represents two important instruments for investigating thermal volcanic activity from space. In this study, we used data those sensors test an original multichannel algorithm, which aims at mapping anomalies a global scale. named Normalized Hotspot Indices (NHI), combines normalized...
Abstract. A stand-alone lidar-based method for detecting airborne hazards aviation in near real time (NRT) is presented. polarization lidar allows the identification of irregular-shaped particles such as volcanic dust and desert dust. The Single Calculus Chain (SCC) European Aerosol Research Lidar Network (EARLINET) delivers high-resolution preprocessed data: calibrated total attenuated backscatter volume linear depolarization ratio series. From these signals, particle coefficient can be...
Several studies have shown the relevance of satellite systems in detecting, monitoring, and characterizing fire events as support to management activities. On other hand, up now, only a few satellite-based platforms provide immediately easily usable information about progress, terms both hotspots, which identify localize active fires, danger conditions affected area. However, this kind is usually provided through separated layers, without any synthetic indicator which, indeed, could be...
Every year about fifty volcanoes erupt on average, posing a serious threat for populations living in the neighboring areas. To mitigate volcanic risk, many satellite monitoring systems have been developed. Information from medium infrared (MIR) and thermal (TIR) bands of sensors such as Moderate Resolution Imaging Spectroradiometer (MODIS) Visible Infrared Radiometer Suite (VIIRS) is commonly exploited this purpose. However, potential daytime shortwave (SWIR) observations Sea Land Surface...
  Wildfires are a worldwide phenomenon with local and global effects. They may pose risk for life infrastructures, degrading air quality perturbing large areas over wide variety of biomes. The fire severity, frequency occurrence, duration seasons have increased in recent decades. Climate change has undoubtedly played role this growth, as rising temperatures, changes precipitation patterns winds, more extended drought periods all contributed to danger. Many satellite-based methods...
The devastating fire events occurring during the intense season of 2023 have shown importance developing efficient detection methods capable supporting management activities. An enhanced configuration Normalized Hotspot Indices (NHI) algorithm has been developed in this direction to improve mapping by satellite through near infrared (NIR) and short-wave (SWIR) data (up 20 m spatial resolution) from Operational Land Imager (OLI/OLI2) Multispectral Instrument (MSI) aboard Landsat-8/9 (L8/9)...
On 16 February 2021, an eruptive paroxysm took place at Mt. Etna (Sicily, Italy), after continuous Strombolian activity recorded summit craters, which intensified in December 2020. This was the first of 17 short, but violent, events occurring during February–April mostly a time interval about 2–3 days between each other. The paroxysms produced lava fountains (up to 1000 m high), huge tephra columns 10–11 km above sea level), and pyroclastic flows, expanding 2–4 towards East South. last...
Dust outbreaks are meteorological phenomena of great interest for scientists and authorities (because their impact on the climate, environment, human activities), which may be detected, monitored, characterized from space using different methods procedures. Among recent dust detection algorithms, RSTDUST multi-temporal technique has provided good results in geographic areas (e.g., Mediterranean basin; Arabian Peninsula), exhibiting a better performance than traditional split window methods,...
In May 2016, three powerful paroxysmal events, mild Strombolian activity, and lava emissions took place at the summit crater area of Mt. Etna (Sicily, Italy). During, immediately after eruption, part North-East (NEC) collapsed, while extensive subsidence affected Voragine (VOR). Since end eruptions, a diffuse fumarolic activity occurred from fracture system that cuts entire area. Starting 7 August, small vent (of ~20–30 m in diameter) opened up within VOR crater, emitting high-temperature...
Natural gas flaring (GF) is a longstanding problem for the oil industry. Recent estimates indicate that this phenomenon has increased to levels recorded full decade earlier. While in 2020 there was decline global GF due COVID-19 pandemic, data suggest continues be persistent issue, with solutions remaining difficult or uneconomical certain countries. Nighttime satellite products are widely used map and monitor affected areas, partially filling general lack of information from companies...
The Agung volcano (Bali; Indonesia) erupted in later November 2017 after several years of quiescence. Because ash emissions, hundreds flights were cancelled, causing an important air traffic disruption Indonesia. We investigate those emissions from space by applying the RSTASH algorithm for first time to Himawari-8 data and using ad hoc implementation scheme reduce elaboration processes. is a new generation Japanese geostationary meteorological satellite, whose AHI (Advanced Himawari Imager)...
In this work, we assessed the possible relation of ionospheric perturbations observed by Detection Electro-Magnetic Emissions Transmitted from Earthquake Regions (DEMETER), Global Positioning System total electron content (GPS TEC), National Oceanic and Atmospheric Administration (NOAA)-derived outgoing longwave-Earth radiation (OLR), atmospheric chemical potential (ACP) measurements, with volcanic Saharan dust events identified ground satellite-based medium infrared/thermal infrared...
In the evening of 20 March 2010, after about two centuries quiescence, an effusive eruption took place at Eyjafjöll (Iceland) volcano, from a small vent localized on northeast flank (Fimmvörduháls Pass) volcano edifice. On 31 March, new eruptive fissure opened same region emitting lava. About 2 weeks later, 14 April, strong explosive under Eyjafjallajökull glacier, injecting copious amounts ash in atmosphere and causing unprecedented air traffic disruption Northern Central Europe. this...
Lombardy is a region of Northern Italy characterized by an alpine/continental climate, where, in winter, strong dry winds and scarce plants hydration frequently cause surface fires with relatively low intensity level. In Liguria, coastal Northwestern Italy, climate vegetation conditions are different from Lombardy; both winter summer, severe forest occur. This study based on the investigation fire regimes characterizing aforementioned regions, using Advanced Very High Resolution Radiometer...
The Eyjafjallajökull (Iceland) volcanic eruption of April-May 2010 caused unprecedented air-traffic disruption in Northern Europe, revealing some important weaknesses current operational ash-monitoring and forecasting systems encouraging the improvement methods procedures for supporting activities Volcanic Ash Advisory Centers (VAACs) better. In this work, we compare two established satellite-based algorithms ash detection, namely RSTASH London VAAC method, both exploiting sensor data...
