iy_id

property Workspace.iy_id

Identification number of iy.

This variable is intended to be an identification number for individual calculations of iy. This id-number can e.g. be used as input to WriteXMLIndexed(), to link filenames to the different calculations.

Some methods sets and updates iy_id. The general numbering scheme is:

xxxyyycba

where xxx identifies the row in sensorPos/los (i.e. the mblock_index), yyy identifies pencil beam direction inside measurement block (should in general match a row in mblock_dlos), and cba identies later legs of total propagation paths, where a, b and c identifies secondary, tertiary and quaternary part, respectively. 1-based numbering is used. That is, the primary path of the first pencil beam of the first measurement block has iy_id = 001001000.

Accordingly, the primary propagation path has cba = 000. If the primary path intersects with the surface, and the downwelling radiation is calculated for three directions, these secondary paths get cba = 001, 002 and 003. If tertiary paths appear, they have numbers such as 011.

As the numbering scheme has nine positions, it is suitable to store files as: WriteXMLIndexed(output_file_format,iy_id,in,filename,9)

Setting of iy_id is not yet supported together with scattering calculations. The value of iy_id then differs, it is either set to 0 or keeps its value set by yCalc().
