The exploitation of complementary and redundant information on atmospheric targets simultaneously observed by multiple independent data sources, such as the atmospheric Sentinels, has intrinsic potential to extend the quality of geophysical products beyond the limits already set by the challenging requirements of the Copernicus program for the atmosphere. Synergistic use of measurements from the Sentinel-5p satellite, launched on October 13th, 2017, from the Sentinel-4 and Sentinel-5 and their contributing missions MTG and MSG, can take advantage of different spectral coverage from the UV, to the Visible, to the Thermal Infrared region and observation geometry on Low Earth Orbit and Geostationary platforms.

First results from assimilation experiments conducted using the TM5 data assimilation systems applied to Sentinel-4 and Sentinel-5 standard retrieval products and to the corresponding fused profiles will be presented and discussed. An estimate of the impact of the advanced quality attained for the ozone profiles will be given for derived products such as tropospheric ozone column and ultraviolet surface radiation of immediate relevance for applications.

Abstract
The exploitation of complementary and redundant information on atmospheric targets simultaneously observed by multiple independent data sources, such as the atmospheric Sentinels, has intrinsic potential to extend the quality of geophysical products beyond the limits already set by the challenging requirements of the Copernicus program for the atmosphere. Synergistic use of measurements from the Sentinel-5p satellite, launched on October 13th, 2017, from the Sentinel-4 and Sentinel-5 and their contributing missions MTG and MSG, can take advantage of different spectral coverage from the UV, to the Visible, to the Thermal Infrared region and observation geometry on Low Earth Orbit and Geostationary platforms. The use of simultaneous retrieval or data fusion techniques is fit for purpose of merging datasets from different measurements and combination with state-of-the-art modeling capabilities is offered by data assimilation systems. The Horizon 2020 project AURORA (Advanced Ultraviolet Radiation and Ozone Retrieval for Applications) is now investigating a novel approach based on sequential application of the innovative Complete Data Fusion technique and of data assimilation models (TM5, IFS and C-IFS) to synthetic data of Sentinel-4 and Sentinel-5 to obtain a unique product for the vertical profile of atmospheric ozone. First results from assimilation experiments conducted using the TM5 data assimilation systems applied to Sentinel-4 and Sentinel-5 standard retrieval products and to the corresponding fused profiles will be presented and discussed. An estimate of the impact of the advanced quality attained for the ozone profiles will be given for derived products such as tropospheric ozone column and ultraviolet surface radiation of immediate relevance for applications. The presentation will be finally focusing on the progress status of the activities for development of two applications - HappySun and AirPortal - using UV surface radiation and Ozone products from AURORA for demonstration purposes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
