Class JB2008SpaceEnvironmentData

java.lang.Object

org.orekit.models.earth.atmosphere.data.JB2008SpaceEnvironmentData

All Implemented Interfaces:

Serializable, JB2008InputParameters

public class JB2008SpaceEnvironmentData
extends Object
implements JB2008InputParameters

This class provides a container for the solar indices data required by the JB2008 atmospheric model. This container only stores information provided in the SOLFSMY and DTCFILE text file provided by Space Environment Technologies. Therefore it doesn't provide the geomagnetic storm indices available in the SOLRESAP file. The DataLoader implementations and the parsing are handled by the SOLFSMYDataLoader DtcDataLoader classes.

Data are available on Space Environment Technologies' website. The work done for this class is based on the CssiSpaceWeatherData class by Clément Jonglez, the JB2008 interface by Pascal Parraud, and corrections for the CssiSpaceWeatherData implementation by Bryan Cazabonne and Evan Ward.

Constructor Detail

JB2008SpaceEnvironmentData

@DefaultDataContext
public JB2008SpaceEnvironmentData(String supportedNamesSOL,
                                                      String supportedNamesDTC)

Simple constructor. This constructor uses the default data context.

Parameters:

supportedNamesSOL - regular expression for SOLFSMY space weather files names with variations allowed between SOLFSMY and the file extension.

supportedNamesDTC - regular expression for DTCFILE files names with variations allowed between DTCFILE and the file extension.

JB2008SpaceEnvironmentData

public JB2008SpaceEnvironmentData(String supportedNamesSOL,
                                  String supportedNamesDTC,
                                  DataProvidersManager dataProvidersManager,
                                  TimeScale utc)

Constructor that allows specifying the source of the SOLFSMY space weather file. This constructor takes a supplementary argument, the supported names for DTCFILE, in order to setup the second loader.

Parameters:

supportedNamesSOL - regular expression for SOLFSMY space weather files names with variations allowed between SOLFSMY and the file extension.

supportedNamesDTC - regular expression for DTCFILE files names with variations allowed between DTCFILE and the file extension.

dataProvidersManager - provides access to auxiliary data files.

utc - UTC time scale.
