Long-term trends in the ionosphere and upper atmosphere parameters - Results derived in the WP1.5 of the COST 271 project.
Original language description
The first task in the WP1.5 of the COST 271 project is directed to the investigation of the practical importance of possible long-term trends in ionospheric prediction models. Using observations of about 50 different ionosonde stations with more than 30years data series of foF2 and hmF2, trends have been derived with the solar sunspot number R12 as index of the solar activity. This R12 index is normally used in ionospheric prediction models. The final result of this trend analysis is that the scatter of the trends derived from the data of the individual stations is relatively large, the calculated global mean values of the foF2 and hmF2 trends, however, are relatively small. Therefore, these small global trends can be neglected for practical purposesand must not be considered in ionospheric prediction models. This conclusion is in agreement with the results of other investigations analyzing data of globally distributed stations. The second more scientific task of the WP1.5 dealing wi
