public interface DTM2000InputParameters extends Serializable
Container for solar activity data, compatible with DTM2000 Atmosphere model. This model needs mean and instantaneous solar flux and geomagnetic incides to compute the local density. Mean solar flux is (for the moment) represented by the F10.7 indices. Instantaneous flux can be set to the mean value if the data is not available. Geomagnetic acivity is represented by the Kp indice, which goes from 1 (very low activity) to 9 (high activity).

All needed solar activity data can be found on the NOAA (National Oceanic and Atmospheric Administration) website.
