Perform a forward calculation using the TREx Auroral Transport Model and the supplied input
parameters. Note that this function utilizes the UCalgary Space Remote Sensing API to perform
the calculation.
The ATM model is 1D and time-independent. However, the optional parameters `timescale_auroral`
and `timescale_transport` provide limited support for time-dependent and transport process. The
`timescale_auroral` parameter (T0) is the duration of the precipitation. The `timescale_transport`
parameter is defined by L/v0, in which L is the dimension of the auroral structure, and v0 is the
cross-structure drift speed. The model quasi-analytically solves the continuity equation under a
square input (with time duration T0 and spatial width L) input of precipitation. The initial/boundary
conditions are given by IRI. The output yields the mean density/VER over [0-L] at time T0.
Args:
timestamp (datetime.datetime):
Timestamp for the calculation. This value is expected to be in UTC, and is valid for
any value up to the end of the previous day. Any timezone data will be ignored. This
parameter is required.
geodetic_latitude (float):
Latitude in geodetic coordinates: -90.0 to 90.0. This parameter is required.
geodetic_longitude (float):
Longitude in geodetic coordinates: -180.0 to 180.0. This parameter is required.
output (ATMForwardOutputFlags):
Flags to indicate which values are included in the output. See
[`ATMForwardOutputFlags`](classes_forward.html#pyucalgarysrs.models.atm.classes_forward.ATMForwardOutputFlags)
for more details. This parameter is required.
maxwellian_energy_flux (float):
Maxwellian energy flux in erg/cm2/s. Default is 10. This parameter is optional.
gaussian_energy_flux (float):
Gaussian energy flux in erg/cm2/s. Default is 0.0. Note that `gaussian_peak_energy` and
`gaussian_spectral_width` must be specified if the `gaussian_energy_flux` is not 0.
This parameter is optional.
maxwellian_characteristic_energy (float):
Maxwellian characteristic energy in eV. Default is 5000. Note that `maxwellian_characteristic_energy`
must be specified if the `maxwellian_energy_flux` is not 0. This parameter
is optional.
gaussian_peak_energy (float):
Gaussian peak energy in eV. Default is 1000. Note this parameter must be specified if
the `gaussian_energy_flux` is not 0. This parameter is optional.
gaussian_spectral_width (float):
Gaussian spectral width in eV. Default is 100. Note this parameter must be specified if
the `gaussian_energy_flux` is not 0. This parameter is optional.
nrlmsis_model_version (str):
NRLMSIS version number. Possible values are `00` or `2.0`. Default is `2.0`. This parameter is
optional. More details about this empirical model can be found [here](https://ccmc.gsfc.nasa.gov/models/NRLMSIS~00/),
and [here](https://ccmc.gsfc.nasa.gov/models/NRLMSIS~2.0/).
oxygen_correction_factor (float):
Oxygen correction factor used to multiply by in the empirical model. Default is 1. This parameter
is optional.
timescale_auroral (int):
The duration of the precipitation, in seconds. Default is 600 (10 minutes). This parameter is optional.
timescale_transport (int):
Defined by L/v0, in which L is the dimension of the auroral structure, and v0 is the cross-structure drift
speed. Represented in seconds. Default is 600 (10 minutes). This parameter is optional.
atm_model_version (str):
ATM model version number. Possible values are only '1.0' at this time, but will have
additional possible values in the future. This parameter is optional.
custom_spectrum (ndarray):
A 2-dimensional numpy array (dtype is any float type) containing values representing the
energy in eV, and flux in 1/cm2/sr/eV. The shape is expected to be [N, 2], with energy in
[:, 0] and flux in [:, 1]. Note that this array cannot contain negative values (SRSAPIError
will be raised if so). This parameter is optional.
no_cache (bool):
The UCalgary Space Remote Sensing API utilizes a caching layer for performing ATM
calculations. If this variation of input parameters has been run before (and the
cache is still valid), then it will not re-run the calculation. Instead it will
return the cached results immediately. To disable the caching layer, set this
parameter to `True`. Default is `False`. This parameter is optional.
timeout (int):
Represents how many seconds to wait for the API to send data before giving up. The
default is 30 seconds, or the `api_timeout` value in the super class' `pyucalgarysrs.PyUCalgarySRS`
object. This parameter is optional.
Returns:
An [`ATMForwardResult`](classes_forward.html#pyucalgarysrs.models.atm.classes_forward.ATMForwardResult)
object containing the requested output data, among other values.

Note that this function utilizes the UCalgary Space Remote Sensing API to perform the calculation. The ATM model is 1D and time-independent. However, the optional parameters `timescale_auroral` and `timescale_transport` provide limited support for time-dependent and transport process. The `timescale_auroral` parameter (T0) is the duration of the precipitation. The `timescale_transport` parameter is defined by L/v0, in which L is the dimension of the auroral structure, and v0 is the cross-structure drift speed. The model quasi-analytically solves the continuity equation under a square input (with time duration T0 and spatial width L) input of precipitation. The initial/boundary conditions are given by IRI. The output yields the mean density/VER over [0-L] at time T0. Args: timestamp (datetime.datetime): Timestamp for the calculation. This value is expected to be in UTC, and is valid for any value up to the end of the previous day. Any timezone data will be ignored. This parameter is required. geodetic_latitude (float): Latitude in geodetic coordinates: -90.0 to 90.0. This parameter is required. geodetic_longitude (float): Longitude in geodetic coordinates: -180.0 to 180.0. This parameter is required. output (ATMForwardOutputFlags): Flags to indicate which values are included in the output. See [`ATMForwardOutputFlags`](classes_forward.html#pyucalgarysrs.models.atm.classes_forward.ATMForwardOutputFlags) for more details. This parameter is required. maxwellian_energy_flux (float): Maxwellian energy flux in erg/cm2/s. Default is 10. This parameter is optional. gaussian_energy_flux (float): Gaussian energy flux in erg/cm2/s. Default is 0.0. Note that `gaussian_peak_energy` and `gaussian_spectral_width` must be specified if the `gaussian_energy_flux` is not 0. This parameter is optional. maxwellian_characteristic_energy (float): Maxwellian characteristic energy in eV. Default is 5000. Note that `maxwellian_characteristic_energy` must be specified if the `maxwellian_energy_flux` is not 0. This parameter is optional. gaussian_peak_energy (float): Gaussian peak energy in eV. Default is 1000. Note this parameter must be specified if the `gaussian_energy_flux` is not 0. This parameter is optional. gaussian_spectral_width (float): Gaussian spectral width in eV. Default is 100. Note this parameter must be specified if the `gaussian_energy_flux` is not 0. This parameter is optional. nrlmsis_model_version (str): NRLMSIS version number. Possible values are `00` or `2.0`. Default is `2.0`. This parameter is optional.

Default is 1. This parameter is optional. timescale_auroral (int): The duration of the precipitation, in seconds. Default is 600 (10 minutes). This parameter is optional. timescale_transport (int): Defined by L/v0, in which L is the dimension of the auroral structure, and v0 is the cross-structure drift speed. Represented in seconds. Default is 600 (10 minutes). This parameter is optional. atm_model_version (str): ATM model version number. Possible values are only '1.0' at this time, but will have additional possible values in the future. This parameter is optional. custom_spectrum (ndarray): A 2-dimensional numpy array (dtype is any float type) containing values representing the energy in eV, and flux in 1/cm2/sr/eV. The shape is expected to be [N, 2], with energy in [:, 0] and flux in [:, 1]. Note that this array cannot contain negative values (SRSAPIError will be raised if so). This parameter is optional. no_cache (bool): The UCalgary Space Remote Sensing API utilizes a caching layer for performing ATM calculations. If this variation of input parameters has been run before (and the cache is still valid), then it will not re-run the calculation. Instead it will return the cached results immediately. To disable the caching layer, set this parameter to `True`. Default is `False`. This parameter is optional. timeout (int): Represents how many seconds to wait for the API to send data before giving up. The default is 30 seconds, or the `api_timeout` value in the super class' `pyucalgarysrs.PyUCalgarySRS` object. This parameter is optional.
