iy_main_agenda

property Workspace.iy_main_agenda

Calculation of a single monochromatic pencil beam spectrum.

The task of the agenda is to calculate the monochromatic pencil beam spectrum for the position specified by rte_pos and the viewing direction specified by rte_los.

Methods for this agenda can either handle the complete calculation, make use of e.g. iy_cloudbox_agenda or be restricted to special cases. See the documentation for the different methods.

The include-file ‘agendas.arts’ predefines some typical alternatives that can be used directly, or adapted for specific applications.

Parameters:

• iy (Matrix) – Monochromatic pencil beam radiance spectrum. See iy [OUT]

• iy_aux (ArrayOfMatrix) – Data auxiliary to iy. See iy_aux [OUT]

• ppath (Ppath) – The propagation path for one line-of-sight. See ppath [OUT]

• diy_dx (ArrayOfTensor3) – Derivative of iy with respect to retrieval quantities. See diy_dx [INOUT]

• geo_pos (Vector) – Geo-position of a measurement. See geo_pos [OUT]

• iy_agenda_call1 (Index) – Flag to handle recursive calls of iy_main_agenda. See iy_agenda_call1 [IN]

• iy_transmittance (Tensor3) – Transmittance to be included in iy. See iy_transmittance [IN]

• iy_aux_vars (ArrayOfString) – Selection of quantities for iy_aux and when applicable also y_aux. See iy_aux_vars [IN]

• iy_id (Index) – Identification number of iy. See iy_id [IN]

• iy_unit (String) – Selection of output unit for radiative transfer methods. See iy_unit [IN]

• cloudbox_on (Index) – Flag to activate the cloud box. See cloudbox_on [IN]

• jacobian_do (Index) – Flag to activate (clear-sky) Jacobian calculations. See jacobian_do [IN]

• f_grid (Vector) – The frequency grid for monochromatic pencil beam calculations. See f_grid [IN]

• nlte_field (EnergyLevelMap) – The field of NLTE temperatures and/or ratios. See nlte_field [IN]

• rte_pos (Vector) – A geographical position for starting radiative transfer calculations. See rte_pos [IN]

• rte_los (Vector) – A line-of-sight for (complete) radiative transfer calculations. See rte_los [IN]

• rte_pos2 (Vector) – A second geographical position to define the geometry for. See rte_pos2 [IN]
