Abstract
Abstract. Given the importance of the atmospheric aerosol, the number of instruments and measurement networks which focus on its characterization are growing. Many challenges are derived from standardization of protocols, monitoring of the instrument status to evaluate the network data quality and manipulation and distribution of large volume of data (raw and processed). CÆLIS is a software system which aims at simplifying the management of a network, providing tools by monitoring the instruments, processing the data in real time and offering the scientific community a new tool to work with the data. Since 2008 CÆLIS has been successfully applied to the photometer calibration facility managed by the University of Valladolid, Spain, in the framework of Aerosol Robotic Network (AERONET). Thanks to the use of advanced tools, this facility has been able to analyze a growing number of stations and data in real time, which greatly benefits the network management and data quality control. The present work describes the system architecture of CÆLIS and some examples of applications and data processing.
Highlights
The atmospheric aerosols are defined as solid or liquid particles suspended in the atmosphere
Such work cannot be accomplished manually in near-real time (NRT) for a large number of sites. It was necessary for the calibration facility at GOA to implement an automatic mechanism to help manage the network and facilitate weekly data checks needed to guarantee the quality of the data
The same information will be used by the system when data from the instruments reach the server and CÆLIS will compare the received information with reference registers stored in the database to know if the instrument is working properly and using the correct configuration
Summary
The atmospheric aerosols are defined as solid or liquid particles suspended in the atmosphere. Led by NASA (National Aeronautics and Space Administration; http://aerosnet.gsfc.nasa.gov) and PHOTONS (PHOtométrie pour le Traitement Opérationnel de Normalisation Satellitaire; http://loaphotons.univ-lille1.fr/), AERONET is built as a federation of sub-networks with highly standardized procedures: instrument, calibration, processing and data distribution It was created in the 1990s with the objective of global monitoring of aerosol optical properties from the ground, as well as validating satellite retrievals of aerosols. Such work cannot be accomplished manually in near-real time (NRT) for a large number of sites In this context, it was necessary for the calibration facility at GOA to implement an automatic mechanism (in addition to the standard mechanism of AERONET) to help manage the network and facilitate weekly data checks needed to guarantee the quality of the data. Some ideas implemented in CÆLIS are inspired by these tools
