Abstract
In the frame of the FP7 POPDAT project the Ionosphere Waves Service (IWS) has been developed and opened for public access by ionosphere experts. IWS is forming a database, derived from archived ionospheric wave records to assist the ionosphere and Space Weather research, and to answer the following questions: How can the data of earlier ionospheric missions be reprocessed with current algorithms to gain more profitable results? How could the scientific community be provided with a new insight on wave processes that take place in the ionosphere? The answer is a specific and unique data mining service accessing a collection of topical catalogs that characterize a huge number of recorded occurrences of Whistler-like Electromagnetic Wave Phenomena, Atmosphere Gravity Waves, and Traveling Ionosphere Disturbances. IWS online service (http://popdat.cbk.waw.pl) offers end users to query optional set of predefined wave phenomena, their detailed characteristics. These were collected by target specific event detection algorithms in selected satellite records during database buildup phase. Result of performed wave processing thus represents useful information on statistical or comparative investigations of wave types, listed in a detailed catalog of ionospheric wave phenomena. The IWS provides wave event characteristics, extracted by specific software systems from data records of the selected satellite missions. The end-user can access targets by making specific searches and use statistical modules within the service in their field of interest. Therefore the IWS opens a new way in ionosphere and Space Weather research. The scientific applications covered by IWS concern beyond Space Weather also other fields like earthquake precursors, ionosphere climatology, geomagnetic storms, troposphere-ionosphere energy transfer, and trans-ionosphere link perturbations.

Summary
Satellite records form the primary base for studying processes in terrestrial plasma (ionosphere, magnetosphere) which have a key importance in geophysical and Space Weather research and monitoring. Despite the large number of satellite missions successfully operated in the Earth environment, only fewer missions provide wave records, especially related to the ionosphere, and these recorded data sets did not form a consistent unified data base or time series of interesting phenomena. Public ionosphere satellite data sources (e.g. http:// sevem.aeronomie.be, http://spidr.ngdc.noaa.gov/spidr/) typically provide optional query capabilities, according to missions, instrument, data type, time window, resulting in a set of raw or level 1 processed recordings. According to the complexity of coupled, parallel physical processes in the ionosphere it is useful and reasonable to handle investigated phenomena, e.g. waves in a way that supports comparative studies, starting already at high level, user-oriented processed data. This report summarizes the concept and first results of a new, public ionosphere wave analysis tool, built and started in frame of the completed EU FP7 POPDAT program
