Description

Adding guassian plume rise for fire emissions
This pull request introduces configurable control over the vertical distribution of fire emissions in the model by adding new parameters for surface and adjacent layer fractions. The changes allow users to specify what fraction of fire emissions should be placed in the surface and adjacent layers, and update the plume rise calculation to use a Gaussian distribution for the remaining emissions. The most important changes are grouped below:

Configuration and Initialization:

• Added two new real variables, fires_surface_frac and fires_adjacent_frac, to aqm_config_type and made them public for configuration.
• Updated aqm_config_read to read fires_surface_frac and fires_adjacent_frac from configuration files, with default values of 0.01 and 0.15, respectively.
• Modified aqm_config_init to assign these new fraction values to the fire emissions structure if the "gbbepx" source is present.
• Set default values for fires_surface_frac and fires_adjacent_frac in the emissions source creation routine.

Plume Rise and Emission Profile Calculation:

• Overhauled the aqm_plume_sofiev routine to:
  • Allocate a configurable fraction of emissions to the surface layer and adjacent layers based on the new parameters.
  • Distribute the remaining emissions using a Gaussian profile centered on the plume rise level.
  • Ensure the emission profile is normalized to the total emissions. [1] [2]

@KaiWang-NOAA I updated the AQM here and it seems to be working. Please try your test again

@bbakernoaa can you resync bbakernoaa:feature/guassian_fire_plume to bring in new commits from NOAA-EMC:develop, so I can open the PR for UFSWM?
