Regular monitoring with heat variation measurements collected, e.g. Thousands of images have been stitched together to obtain a mosaic of the crater zone. We applied atmosphere corrections to calculate infrared absorption by high concentration of water vapor. Despite the harsh logistics and the continuously varying gas concentrations we managed to collect thermal images to estimate the crater zone spatial thermal variations. The low distance ( high resolution) acquisitions have a temperature detail every cm 40, therefore it is possible to detect and observe physical phenomena such as thermodynamic behavior, hot mud and fluids emissions locations and their time shifts. ![]() The mounted thermal camera has peak spectral sensitivity in LW wavelength (μm 10) that is characterized by low water vapor and CO2 absorption. The drone is equipped with GPS and an autopilot system that allows pre-programming the flying path or designing grids. In the framework of the LUSI Lab project (ERC grant n° 308126), in 20, we acquired high resolution infrared images using a specifically equipped remote-controlled drone flying at an altitude of m 100. At this locality we performed surveys over the unreachable erupting crater. Since May 2006 the Indonesian LUSI mud eruption continues to spew boiling mud, water, aqueous vapor, CO2, CH4 and covers a surface of nearly 7 km2. Thermal cameras have the ability to estimate temperature values without contact and therefore can be used in circumstances where objects are difficult or dangerous to reach such as volcanic eruptions. The use of low-cost hand-held infrared (IR) thermal cameras based on uncooled micro-bolometer detector arrays became more widespread during the recent years. High resolution infrared acquisitions droning over the LUSI mud eruption.ĭi Felice, Fabio Romeo, Giovanni Di Stefano, Giuseppe Mazzini, Adriano Although the 6 deg N - 30 deg S Termoskan coverage only slightly overlaps the nominal Mars Pathfinder target range, the implications of Termoskan data for that overlap region and the extrapolations that can be made to other regions give important clues for optimal landing site selection. It simultaneously obtained broadband reflected solar flux data. The Termoskan instrument onboard the Soviet Phobos '88 spacecraft acquired the highest spatial- resolution thermal infrared data obtained for Mars, ranging in resolution from 300 m to 3 km per pixel. Thermal infrared observations of Mars from spacecraft provide physical information about the upper thermal skin depth of the surface, which is on the order of a few centimeters in depth and thus very significant for lander site selection. Implications of high-spatial-resolution thermal infrared (Termoskan) data for Mars landing site selection High-resolution thermal infrared imagery proved highly effective tool for precise heat anomaly detection on the campus, and it can be used by university facility services for effective future maintenance of buildings and grounds. Several hot spots were also identified on the campus for steam pipelines faults. Assessment of the temperature map revealed a number of building structures that may be subject to insulation improvement due to their high surface temperatures leaks. The temperature map then was used to assess the building rooftop conditions and steam line faults in the study area. Ground control data was used to construct the pixel- to-temperature conversion model, which was later used to produce temperature maps of the entire campus and also for validation of the model. A thermal camera with a spectral bandwidth of 3.0-5.0 μm was flown at the average altitude of 600 m, achieving ground resolution of 29 cm. The goal of this project was to map the surface temperature of the University of Northern Iowa campus using high-resolution thermal infrared aerial imageries.
