Titolo: | A method for Cloud Mapping in the Field of View of the Infra-Red Camera during the EUSO-SPB1 flight | Autori: | Alessandro Bruno ANZALONE, ANNA Carlo Vigorito |
Data pubblicazione: | 2019 | Rivista: | POS PROCEEDINGS OF SCIENCE | Titolo del volume in cui è pubblicato il poster: | 36th International Cosmic Ray Conference (ICRC2019) | Numero: | 358 | Abstract: | EUSO-SPB1 was released on April 24th, 2017, from the NASA balloon launch site in Wanaka (New Zealand) and landed on the South Pacific Ocean on May 7th. The data collected by the instruments onboard the balloon were analyzed to search UV pulse signatures of UHECR (Ultra High Energy Cosmic Rays) air showers. Indirect measurements of UHECRs can be affected by cloud presence during nighttime, therefore it is crucial to know the meteorological conditions during the observation period of the detector. During the flight, the onboard EUSO-SPB1 UCIRC camera (University of Chicago Infra-Red Camera), acquired images in the field of view of the UV telescope. The available nighttime and daytime images include information on meteorological conditions of the atmosphere observed in two infra-red bands. The presence of clouds has been investigated employing a method developed to provide a dense cloudiness map for each available infra-red image. The final masks are intended to give pixel cloudiness information at the IR-camera pixel resolution that is nearly 4-times higher than the one of the UV-camera. In this work, cloudiness maps are obtained by using an expert system based on the analysis of different low-level image features. Furthermore, an image enhancement step was needed to be applied as a preprocessing step to deal with uncalibrated data. | Titolo del convegno: | 36th International Cosmic Ray Conference (ICRC2019) | Luogo del convegno: | Madison, WI, U.S.A. | Periodo del convegno: | July 24th-August 1st, 2019 | URI: | http://hdl.handle.net/20.500.12386/30151 | URL: | http://arxiv.org/abs/1909.05917v1 https://pos.sissa.it/cgi-bin/reader/conf.cgi?confid=358 https://pos.sissa.it/358/454/ |
