The videos included herein form the supplementary data for the thesis of Thomas Wilkes (Department of Geography) titled "The development of low-cost ground-based remote sensing instruments and their application in volcanology"

The videos have all previously been published as part of peer-reviewed articles.

Video S1: A video of PiCam SO2 retrievals performed at Drax power station smokestack on 15 August 2016. The camera frame rate was 0.25 Hz.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; McGonigle, A.J.S.; Pering, T.D.; Taggart, A.J.; White, B.S.; Bryant, R.G.; Willmott, J.R. Ultraviolet Imaging with Low Cost Smartphone Sensors: Development and Application of a Raspberry Pi-Based UV Camera. Sensors 2016, 16, 1649.

Video S2: A video of JAI SO2 retrievals performed on Mt. Etna on 19 July 2016, imaging Etna's North East Crater plume. Images have been sub-sampled to achieve a frame rate of 0.25 Hz, in concordance with the PiCam acquisitions.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; Pering, T.D.; McGonigle, A.J.S.; Tamburello, G.; Willmott, J.R. A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements. Remote Sens. 2017, 9, 27.

Video S3: A video of PiCam SO2 retrievals performed on Mt. Etna on 19 July 2016, imaging Etna's North East Crater plume. The camera frame rate was 0.25 Hz.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; Pering, T.D.; McGonigle, A.J.S.; Tamburello, G.; Willmott, J.R. A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements. Remote Sens. 2017, 9, 27.

Video S4: A video of Masaya lava lake temperatures captured with the PiCam thermal imager on 12 June 2017. The camera frame rate was 0.5 Hz.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; Stanger, L.R.; Willmott, J.R.; Pering, T.D.; McGonigle, A.J.S.; England, R.A. The Development of a Low-Cost, Near Infrared, High-Temperature Thermal Imaging System and Its Application to the Retrieval of Accurate Lava Lake Temperatures at Masaya Volcano, Nicaragua. Remote Sens. 2018, 10, 450.

Video S5: A stabilised version of Video S4. The video was stabilised using the Lukas-Kanade method. Whilst small-scale shake is still present, if not enhanced, in this video, larger frame shifts have been minimised by this stabilisation.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; Stanger, L.R.; Willmott, J.R.; Pering, T.D.; McGonigle, A.J.S.; England, R.A. The Development of a Low-Cost, Near Infrared, High-Temperature Thermal Imaging System and Its Application to the Retrieval of Accurate Lava Lake Temperatures at Masaya Volcano, Nicaragua. Remote Sens. 2018, 10, 450.

Video S6: A video of the lava lake mask produced by thresholding temperatures from Video S4. Maroon pixels are identified as the lava lake, exhibiting a temperature of >= 850 oC.
Video is also published as part of the supplementary material for paper: Wilkes, T.C.; Stanger, L.R.; Willmott, J.R.; Pering, T.D.; McGonigle, A.J.S.; England, R.A.
