Auto-Generated Documentation

This page provides an overview of variables. For detailed documentation with types, units, and usage, see the Auto-Generated Doxygen Variables.

Quick Access to Variable Categories

::: canopy selection: variables: true rendering: show_source: false show_bases: false heading_level: 3

Variable Groups

Physical Constants

::: canopy selection: members: - const_mod - fundamental_const - atmos_const - bioemi_const rendering: show_source: false show_bases: false heading_level: 4

Physical and mathematical constants used throughout the model.

Model Configuration Variables

::: canopy selection: members: - canopy_options - canopy_variables rendering: show_source: false show_bases: false heading_level: 4

Model configuration options and main canopy variables.

Aerosol Dry Deposition Option

  • ifcanaeroddep (logical): Enables aerosol dry deposition calculations. Set in the namelist file. When .TRUE., activates urban/non-vegetated and vegetated dry deposition routines.

Input/Output Variables

Input data arrays and file path variables.

Canopy Structure Variables

::: canopy selection: members: - CanopyDistribution - coord_mod - spatial_domain - vertical_domain rendering: show_source: false show_bases: false heading_level: 4

Variables defining canopy structure and spatial domains.

Meteorological Variables

::: canopy selection: members: - canopy_met_input - CanopyWind - CanopyDiffusivity rendering: show_source: false show_bases: false heading_level: 4

Meteorological input and calculated variables.

Process-Specific Variables

::: canopy selection: members: - CanopyDryDeposition rendering: show_source: false show_bases: false heading_level: 4

Variables for dry deposition processes: - ddep_aero(nlon, nlat, modlays) - Vegetated aerosol dry deposition velocity (m/s)

::: canopy selection: members: - CanopyBiogenicEmissions - CanopyPhotolysis - CanopyDryDeposition rendering: show_source: false show_bases: false heading_level: 4

Variables for biogenic emissions, photolysis, and dry deposition processes.
