MSISE2000InputParameters

public class ClassicalMSISE2000SolarData
extends AbstractMSISE2000SolarData

This class represents a solar data container adapted for the MSISE2000 atmosphere model This model of input parameters computes averages for SOME of the ap values required by the MSISE2000 model. See the getApValues(AbsoluteDate) and ContinuousMSISE2000SolarData.getApValues(AbsoluteDate) methods.

Constructor Detail

ClassicalMSISE2000SolarData

public ClassicalMSISE2000SolarData(SolarActivityDataProvider solarData)

Constructor. Builds an instance of a solar data provider adapted for the MSISE2000 atmosphere model

Parameters:

solarData - input solar data

Method Detail

getApValues

public double[] getApValues(AbsoluteDate date)
                     throws OrekitException

Get the array containing the 7 ap values

 ap[0] = ap value averaged over [t0 - 12h; t0 + 12h]
 ap[1] = ap value at given user date
 ap[2] = ap value at given user date - 3 hours
 ap[3] = ap value at given user date - 6 hours
 ap[4] = ap value at given user date - 9 hours
 ap[5] = ap value averaged over [t0 - 36h; t0 - 12h]
 ap[6] = ap value averaged over [t0 - 61h; t0 - 36h]
 
  where t0 is the given user date (parameter "date")

Specified by:

getApValues in interface MSISE2000InputParameters

Specified by:

getApValues in class AbstractMSISE2000SolarData

Parameters:

date - the current date

Returns:

the Ap values

Throws:

OrekitException - if the date is out of range of available data
