"The present Project purpose is the problem-oriented processing of observational data collected and stored by former ionospheric satellite missions – their data mining with the aim to create the database of ionosphere waves catalogues. This is an urgent need of modern space science because its realization will help to improve considerably Space Weather nowcast and forecast and to promote the progress of actual today GMES and other applied studies, e.g., ionospheric monitoring of natural and man-made hazards. At a first stage of the Project fulfillment, the different types of wave data will be selected, processed and arranged in topical catalogues: atmosphere gravity waves, moving plasma disturbances (bubbles, blobs, TID, etc), and ELF-VLF plasma emissions (whistler waves, hisses, etc). Then the Ionosphere Wave Service will be created including the composition of catalogues metadata to provide useful tool to access the database through a web portal. Ionosphere Wave Service will be promoted to a great number of scientists and specialists working in the numerous theoretical and applied space oriented branches.The particular goals of the POPDAT Project are:− Collection of datasets from different sources which concern the wave-like phenomena in the upper atmosphere and ionosphere to form input data field for further processing;− Appropriate design of the flexible software tools for the search of wavelike and/or any other anomalous behaviors detected in the satellite datasets;− Creation of thematic catalogues of ionosphere perturbations, which have known, supposed or unknown origin;− Implementation of a Ionosphere Wave Service accessible to scientific communities and public users;− Creation of Ionosphere Virtual Dynamic Observatory to assist educational activities;− Dissemination and promotion of the Ionosphere Wave Service at topical conferences and in scientific and public press."
