Periodic Reporting for period 1 - DISPEC (SCIENTIFIC EXPLOITATION OF SPACE DATA FOR IMPROVED IONOSPHERIC SPECIFICATION)
Periodo di rendicontazione: 2024-01-01 al 2025-06-30
Context and Objectives
The ionosphere plays a vital role in radio signal propagation, and its variability can significantly impact technological systems. DISPEC addresses the need for improved ionospheric specification by:
* Exploiting Diverse Data Sources: Utilizing data from space missions like Swarm, DORIS, GRACE, GRACE-FO, Spire, and COSMIC-2, alongside ground-based GNSS receivers and ionosonde sounders.
* Developing High-Level Data Products: Creating advanced data products through sophisticated processing techniques to enhance data quality and provide accurate estimates of ionospheric characteristics.
* Analyzing Long-Term Trends: Studying long-term ionospheric trends in relation to atmospheric dynamics and geophysical phenomena by exploiting extended time series data.
The overarching goal is to support research activities that lead to improved ionospheric models, benefiting both scientific understanding and practical applications.
DISPEC's strategy for achieving its objectives and maximizing impact includes:
Standardization and Quality Assurance: Ensuring that the derived data products adhere to Research Data Alliance standards, with specified data quality flags and defined data levels, facilitating adoption by space agencies and data centers.
Integration with Existing Infrastructures: Complementing ESA's Space Science Archives and Space Weather Network, as well as global networks of ionosondes and GNSS receivers, to enhance the capacity of European Research Infrastructures.
Facilitating Research and Model Validation: Providing reliable data products that can be reused by the research community to improve the accuracy of ionospheric models and support their validation.
By advancing beyond the current state of the art in data processing and integration, DISPEC aims to deliver high-quality, standardized data products that can be seamlessly incorporated into existing ionospheric service infrastructures, thereby significantly contributing to the field of space weather research and its practical applications.
