Abstract:

The STRATUS project is designed to meet EU efforts to calibrate and validate ESA earth observation programs by providing the backbone to understand and study new satellite products and to make the first steps to perform complementary measurements for validation and calibration purposes. The main goal of the project is to offer the means to validate and calibrate satellite observations by offering a wide range of ground based unbiased atmospheric products over extended time scales and monitor the stability of satellite products over the envisaged locations. The implementation of the project will help strengthening the know how in satellite validation and help build the required infrastructure to further participate to cal/val activities lead by ESA or the EU.

Aerosol properties retrieval from remote sensing spectroscopic measurements Call name:

Abstract:

AiRFRAME (Aerosol properties retrieval from remote sensing spectroscopic measurements) represents the Romanian contribution to international efforts in setting up a ground-based network of monitoring stations which will be used for the calibration and validation of different product regarding the atmosphere during the commissioning and operational phase of existing and future ESA space missions.

Understanding climate change includes the understanding of the chemistry related to climate and the chemistry–climate interactions on regional scale as well as for the entire System Earth on the global scale which is one of the great challenges in atmospheric science today and still a strongly developing field in climate modelling. Satellites provide the primary resources of obtaining a global perspective and comparing different parts of the globe. But long-term ground-based observational databases are essential to validate their products.

Even when the satellites will be fully operational, the Contributing Missions will continue to be essential, delivering complementary data to ensure that a broad range of observational requirements is satisfied. Information on atmospheric variables could be provided in support of European policies. Services could include the monitoring of air quality, water vapour, aerosols and solar radiation as part of climate monitoring.

This initiative is targeting mostly the calibration-validation activities of Sentinel 5 Precursor (TROPOMI instrument), referring specifically to the NO2 and aerosol products, but also are expected important contributions to ADM-Aeolus, EarthCARE, Sentinel 4, Sentinel 5 precursor and Sentinel 5 missions. AiRFRAME’s objectives are twofold: on one hand, to improve the state-of-the-art monitoring station in Romania, based on existing capacities and upgrades; on the other hand, to extend the number of parameters available from Pandora-2S systems and to increase the potential of calibration/validation activities of ESA space missions. Subsequent scientific objectives referring to the study of horizontal and vertical gradients in a highly polluted area, correlation with meteorology and sources, will be also addressed.

The general objective of the AiRFRAME’s project is to improve the capability of ESA mission’s calibration/validation activities using ground based differential optical absorption spectrometric measurements. A software prototype will be developed during the project implementation, dedicated to Pandora systems retrievals of aerosols properties.

The project is targeting the aerosol retrieval from Pandora system, which is on highly interest in the scientific community, but not yet developed by the network. The number of parameters available in the Pandonia network will be then increased, with aerosol properties. The software represents an original work worldwide from which can benefit all Pandora network systems and other differential absorption spectrometric measurements. Part of the technology proposed to be included here have been already proposed in the literature for other DOAS systems, but now will be extended to other kind of instruments and spectrometric bands.

The consortium operates a large variety of in situ and remote sensing instruments to measure gases and particulates in the atmosphere. Between these an direct-sun DOAS is in use, which is the most accurate technique for deriving column NO2 (C(NO2)) from ground-based instruments conform to the recent studies. Diurnal and seasonal variability will be studied both for the NO2 (with the PANDORA system) and aerosols (with the aerosol lidar).

The Pandora system is part of Pandora network, which ensure a proper utilization of the instruments and larger coverage. The NO2 ground-based monitoring will follow the rules of the existing community, in order to ensure a proper implementation of the measurement and data handling procedures.

The vertical and horizontal variability of the NO2 and aerosols fields in the area of Bucharest will be investigated, as a possible source of error to be included in the TROPOMI’s level 2 products. Complex situations within a satellite pixel area such as: partly clouds, spatial gradients, inhomogeneous terrain, high aerosol loadings, lead to more challenges to the TROPOMI’s Level-2 retrieval algorithms. Bucharest is, from this point of view, a perfect site to test the accuracy and the sensitivity of the retrievals, because of the density of the sources, considerable aerosol loads and changing weather patterns.

Abstract:

The purpose of the project is to develop a state of the art aerosol-typing software prototype based on the classification intelligent algorithms using data from active and passive remote sensing instruments together with satellite imagery and in situ data. The aerosols transport modelling will be also used to develop this software. Using remote sensing data, the dependence of the relative humidity of the aerosol size and density will be analysed and the in order to improve observations of aerosol optical and hygroscopic properties, hence, providing more accurate information on the type of aerosol in each aerosol layer from atmosphere. Combining numerical modelling with the remote sensing measurements the relationship between sources and receptors will be analysed in order to make a correlation between aerosol types and their sources, information important to aerosols classification.

Abstract:

In the context of validation-calibration activities of the satellite data obtained from ESA’s Sentinel 4, 5 and 5P,

the present project proposal aims to develop an integrated scientific platform in which both airborne remote sensing and ground-based facilities will be involved. The main goal is to develop scientific missions for atmospheric research validation of the satellite products and to improve ESA’s Sentinel 4, 5 and 5P data accuracy and long term stability of their related products. In order to achieve the proposed objective of this project, the activities will start with the analysis of state of the art facilities and technologies, continuing with the integration of airborne and ground-based instruments into a complex research platform. Then, a measurement campaign for testing, optimizing and defining the appropriate procedures for using the research platform in Cal/Val and scientific national missions/campaigns will be accomplished. The last step of the project consists in performing a measurement campaign for validation-calibration of ESA’s Sentinel 4, 5 and 5P. All data and results obtained during the measurement campaigns will be integrated in a new developed database, available for scientific community.
