How to calculate the amount of radiation that reaches the observation position after the radiation of a molecule or all molecules in the atmosphere is transmitted by atmospheric radiative transmission (linear integration) under different observation methods

hello,How to calculate the amount of radiation that reaches the observation position after the radiation of a molecule or all molecules in the atmosphere is transmitted by atmospheric radiative transmission (linear integration) under different observation methods?
The different observation methods are shown in the figure below：

vertical 1
vertical 2
For example, how do I change H1, H2, and angle in a tape5 file?

For example, how to calculate the amount of atmospheric radiation after radiation transmission over a certain distance by only one atmospheric molecule, several atmospheric molecules, and all atmospheric molecules, and how to set it in tape5？
How to consider the effects of atmospheric radiation ？

Hi,

Please take a look the following example in the example tar package: run_example_user_defined_upwelling. Compare the TAPE5 with the instructions, which will show you which parameters are defined on which lines. Ruuning LBL will provide both the surface (if looking down) and the atmospheric contributions to the TOA radiation. If you want the contribtion of just one molecule you have several options:

  1. In the TAPE5 set to zero out amounts of the molecules you want to exclude.
  2. Use the HMOL scale option (Record 1.3.a)
  3. Create a line file with just the molecule of interest.

Thank you!! please tell me where is ' run_example_user_defined_upwelling'

@kcadyper hello, where is ' run_example_user_defined_upwelling'

On the LBLRTM GitHub page look for a link to the examples package in the Examples section of the README.md
