Configuration

Coefficients of the regressions constituting the model as well as parameters of different categories of soil and land use are stored in a number of yaml files in parameters/emissions/.

Configuration of inputs

Information about the names and the units of the model inputs is stored and can be configured in config/emissions/inputs.yaml e.g. for monthly temperatures which are represented in variable monthly_temps:

monthly_temps:
  include: True
  name: "Monthly Temperatures"
  long_description: ""
  unit: "deg C"
  unit_latex: "$^o$C"

  • include: (boolean): If the variable is to be included in the output files for reporting.

  • name: (string): Name of the variable

  • long_description: (string): Description of the variable

  • unit: (string): Unit in text format

  • unit_latex: (string): Unit in LaTeX format

Finally, a global flag print_long_descriptions controls whether long descriptions are included alongside the included input variables in the output files.

Configuration of outputs

Similarly to inputs, definitions and units of model outputs and whether they are to be output in the output files, are stored in config/emissions/outputs.yaml, e.g. for pre-impoundment CO2 emissions defined in variable co2_preimp:

co2_preimp:
  include: True
  name: "Preimpoundment CO2 emissions"
  gas_name: "CO2"
  name_latex: "Preimpoundment CO$_2$ emissions"
  unit: "gCO2eq m-2 yr-1"
  unit_latex: "gCO$_2$ m$^{-2}$ yr$^{-1}$"
  long_description: "CO2 emission in the area covered by the reservoir prior to impoundment"
  hint: "Negative values denote C sink (atmosphere to land flux)"

  • include: (boolean): If the variable is to be included in the output files for reporting.

  • name: (string): Name of the variable

  • gas_name: (string): Name of the gas the variable is related to

  • name_latex: (string): variable name in LaTeX format

  • unit: (string): Unit in text format

  • unit_latex: (string): Unit in LaTeX format

  • long_description: (string): Description of the variable

  • hint: (string): Further information about the variable

Configuration of global parameters

Information about global parameters such as e.g. Global Warming Potentials gwp100 is stored in config/emissions/parameters.yaml

gwp100:
  include: True
  name: "Global Warming Potential for a 100-year timescale"
  name_latex: "Global Warming Potential for a 100-year timescale"
  unit: "-"
  unit_latex: "-"
  long_description: ""

Model coefficients

Values of model coefficients, i.e. regressions used to estimate different gas emissions are stored in config/emissions/config.ini file. E.g. coefficients for CO2 emission calculations are listed below.

[CARBON_DIOXIDE]
# Parameters reated to CO2 emissions
k1_diff = 1.8569682
age = -0.329955
temp = 0.0332459
resArea = 0.0799146
soilC = 0.015512
ResTP = 0.2263344
calc = -0.32996
# Conversion from mg~CO2-C~m-2~d-1 to g~CO2eq~m-2~yr-1
# Based on stoichiometric relationship CO2/C = 44/12 and GWP100 of 1.0
conv_coeff = 1.33833
# Global Warming Potential of CO2 over 100 years
co2_gwp100 = 1.0

In addition, various coefficient tables and parameters required to calculate various emission components are stored in multiple YAML files in parameters/emissions/.
