MSISE2000InputParameters

public class ContinuousMSISE2000SolarData
extends AbstractMSISE2000SolarData

This class represents a solar data container adapted for the MSISE2000 atmosphere model This model of input parameters computes averages for ALL the ap values required by the MSISE2000 model. See the ClassicalMSISE2000SolarData.getApValues(AbsoluteDate) and getApValues(AbsoluteDate) methods.

Constructor Detail

ContinuousMSISE2000SolarData

public ContinuousMSISE2000SolarData(SolarActivityDataProvider solarData)

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

Parameters:

solarData - input solar data

Method Detail

getInstantFlux

public double getInstantFlux(AbsoluteDate date)
                      throws OrekitException

Get the value of the instantaneous solar flux. This method returns the instant flux value at (date - 1 day).

Specified by:

getInstantFlux in interface MSISE2000InputParameters

Overrides:

getInstantFlux in class AbstractMSISE2000SolarData

Parameters:

date - the current date

Returns:

the instantaneous solar flux

Throws:

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

getMeanFlux

public double getMeanFlux(AbsoluteDate date)
                   throws OrekitException

Get the 81 day average of F10.7 flux. This method computes the trapezoidal average.

Specified by:

getMeanFlux in interface MSISE2000InputParameters

Overrides:

getMeanFlux in class AbstractMSISE2000SolarData

Parameters:

date - the current date

Returns:

the mean solar flux

Throws:

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

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 averaged over [t0 -  1h30; t0 +  1h30]
 ap[2] = ap value averaged over [t0 -  4h30; t0 -  1h30]
 ap[3] = ap value averaged over [t0 -  7h30; t0 -  4h30]
 ap[4] = ap value averaged over [t0 - 10h30; t0 -  7h30]
 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
