Detailed Description
Model types
There are currently five distinct model types used in the atmosphere:- atm::VRayleighModel for computing molecular scattering and attenuation
- atm::VProfileModel for describing the molecular atmosphere profile
- atm::VMieModel for computing aerosol scattering and attenuation
- atm::VFluorescenceModel for computing fluorescence yield
- atm::VCherenkovModel for computing Cherenkov radiation
- atm::VCloudModel for computing near-real time cloud coverage
Model selection and naming conventions
The choice of which models to employ is specified in the AtmosphereInterface.xml configuration file. You will find it here:path-to-offline-install/share/auger-offline/config/AtmosphereInterface.xml
This file contains a list of elements whose names describe the model types, with the specific instance of the model to be used written between the element tags. For example, the configuration file might read:
<AtmosphereInterfaceConfig> <RayleighModel> ParametricXML </RayleighModel> <ProfileModel> MonthlyAvgDB </ProfileModel> <MieModel> MeasuredDB </MieModel> <FluorescenceModel> Nagano2004 </FluorescenceModel> <CherenkovModel> Analytical </CherenkovModel> <CloudModel> LidarCloudDB </CloudModel> </AtmosphereInterfaceConfig>
The names for the model instances are supposed to indicate what sort of algorithm is employed to do the calculation, and where the data for the calculation are taken from. For example,
<MieModel> MeasuredDB </MieModel>
indicates that aerosol scattering and attenuation are computed using measurements stored in the database. In contrast,
<MieModel> ParametricXML </MieModel>
indicates that a parametrization is used, with parameters kept in an XML file.Note that there are also some models which are capable of automatically choosing the most appropriate data source to use, so that you do not have to make the choice in the Atmosphere interface configuration. Such models are called "super" models, and appear like this in the configuration file:
<MieModel> Super </MieModel>
In the case of the Mie super model, the calculations use measurements from the database if they are available, or a parametrization in case no data are found in the database.The various model instances are given by the list of classes at top of this section. To determine the model instance name to use in the configuration file from the class name for the model, you generally just have to strip off the last two word from the class name. For example, the model coded in the class atm::MeasuredDBMieModel is called MeasuredDB in the <MieModel> element of the AtmosphereInterface.xml configuration file.If you want to see where the model names used in the configuration file are actually mapped on to instances of the model types, you can look in the source code for atm::AtmosphereModelsManager.
