<name>Acquisition for the EIS foF2 Long Term Prediction Maps</name>
<description>The predicted values are estimated through the implementation of the upgraded Simplified Ionospheric Regional Model (SIRM, Zolesi et al., 1993; 1996).
This combines the standard SIRM output in the middle latitudes (up to 60°N) with the CCIR output for the higher latitudes. The algorithm receives as input
the predicted sunspot number R12 provided by SWPC NOAA (http://www.swpc.noaa.gov/).</description>
