Dr Laura Valore (NA)25/09/2018, 09:30Aerosol attenuation profiles of the UV light have been measured at the Pierre Auger Observatory since the very beginning, dating back to 2004. The Central Laser Facility is operational since 2004, and its twin, the eXtreme Laser Facility, is operational since late 2010. Two techniques are applied to produce the hourly aerosol attenuation profiles that are continuously used in the data...Go to contribution page

Dr Bianca Keilhauer (Karlsruhe Institute of Technology KIT)25/09/2018, 10:00The Pierre Auger Observatory for detecting ultra-high energy cosmic rays has been founded in 1999. After a main planning and construction phase of about five years, the regular data taking started in 2004, but it took another four years until the full surface detector array was deployed. In parallel to the main detectors of the Observatory, a comprehensive set of instruments for monitoring the...Go to contribution page

Dr Dusan Mandat (Institute of Physics Academy of Sciences of the Czech Republic)25/09/2018, 10:30The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a proposed low-cost, large-area, next-generation experiment for the detection of ultrahigh-energy cosmic rays (UHECRs) via the atmospheric fluorescence technique. Two FAST telescopes are installed and operating at the Black Rock Mesa site of the Telescope Array Experiment in Utah, USA. Knowledge of the properties of the...Go to contribution page

Vincenzo Rizi (GSGC)25/09/2018, 11:30The Raman lidar (RL) at the Central (Raman) Laser Facility of the Pierre Auger Observatory in Argentina, has been operational since September 2013. In this talk, the Auger RL performance is discussed in terms of the data quality for the assessment of the aerosol contribution to the atmospheric UV optical transparency, and how much this is important for the reconstruction of the UHECR...Go to contribution page

Mr Marco Iarlori (LNGS)25/09/2018, 12:00This talk presents the ARCADE Raman lidar that has been tested and validated at L'Aquila before the deployment at CTA North site. The performances and the limitation of Raman lidar (RL) technique are also discussed: - the technical constrains of RL systems; - the strategy of the observations at ORM site; - the main signal analysis issues, i.e., how to estimate VAOD profiles, and data...Go to contribution page

Dr Markus Gaug (Universitat Autònoma de Barcelona and IEEC-CERES)25/09/2018, 12:30The IFAE/UAB Raman LIDAR project aims to develop a Raman LIDAR suitable for the online atmospheric calibration along the line-of-sight of the Northern array of the CTA. Requirements for such a solution include the ability to characterize aerosol extinction to distances of 30 m with an accuracy better than 5%, within time scales of less than 1 minute. The Raman LIDAR consists therefore of a...Go to contribution page

Dr Alessia Sannino (CNISM - Università FedericoII di Napoli)25/09/2018, 13:00A lidar for aerosol monitoring with conventional optical design can provide good quality signals from several hundred meters up to tens of kilometres above the ground, but the aerosol load is mainly contained (up to 80%) in the planetary boundary layer that can have a height of the order of hundreds of meters. Therefore, the measurement of the complete aerosol extinction profile is generally a...Go to contribution page

Dr Simon Mackovjak (Department of Space Physics, Institute of Experimental Physics, Slovak Academy of Sciences)25/09/2018, 15:00The night time UV radiation composed of airglow, starlight, and zodiacal light act as a background for detection of the Extensive Air Shower (EAS) fluorescence induced by Ultra-High Energy Cosmic Rays (UHECR). To monitor this background, we have developed the one-pixel instrument that provides the absolute intensities within the spectral range 300 - 480 nm in the one second temporal...Go to contribution page

Dr Jan Ebr (Institue of Physics, Prague)25/09/2018, 15:30The idea of using stellar photometry for atmospheric monitoring for optical experiments in high-energy astrophysics is seemingly straightforward, but reaching high precision of the order of 0.01 in the determination of the vertical aerosol optical depth (VAOD) has proven consistently difficult. Wide-field photometry in a large span of altitudes allows fast determination of VAOD independently...Go to contribution page

Dr Petr Janecek (Institute of Physics AS CR)25/09/2018, 16:00A FRAM telescope is a system consisting of a robotic mount, a large-format CCD camera and a fast telephoto lens that can be used for atmospheric monitoring at any site whenever information about the atmospheric transparency is required with high spatial or temporal resolution and where continuous use of laser-based methods for this purpose would interfere with other bservations. The original...Go to contribution page

28. Development of a High Spectral Resolution Lidar for day-time measurements of aerosol extinction.Dr Alessia Sannino (CNISM - Università FedericoII di Napoli)25/09/2018, 17:00Lidar technique is the most performing way to obtain the atmosphere vertical profile of aerosol optical properties with high space-time resolution. With conventional lidars, the retrieval of aerosol optical properties (as the extinction profile) is realizable only with assumptions on aerosol extinction-to-backscatter ratio or with Raman measurement achievable in night-time. In order to...Go to contribution page

Mr Stanislav Stefanik (Charles University, Prague)25/09/2018, 17:30The Cherenkov Telescope Array (CTA), the future ground-based gamma-ray observatory, will require reliable monitoring of the atmosphere which is an inherent part of the detector. We discuss here the implementation of the extended method of the Cherenkov Transparency Coefficient for the atmospheric calibration for the CTA. The method estimates the atmospheric transmission of Cherenkov light,...Go to contribution page

Dr Nataliia Borodai (Institute of Nuclear Physics PAN, Krakow)25/09/2018, 18:00Aerosol optical depth can be retrieved from measurements performed by Moderate Resolution Imaging Spectroradiometer (MODIS) satellite instrument. The MODIS satellite system includes two polar satellites, Terra and Aqua. Each of them flies over the Pierre Auger Observatory once a day, providing two measurements of aerosols per day and covering the whole area of the Observatory. MODIS aerosol...Go to contribution page
