Atmospheric chemistry box-model for the MCM
The model is very slow when the entire MCM is used as chemical mechanism, as opposed to just a subset of it. It takes up to 5 days to run...
I set the JFAC to 'CONSTRAINED' and used 'J4' in photolysisConstrained.config and a corresponding fi le with the constraint data present in the model/constraints/photolysis/ However, I am getting the following...
- ~~`instantaneousRates`: change name to `reactionRates` (solved by #349) add column with reaction number, add header~~ - `lossRates.output` and `productionRates.output`: the current "3D" format is awkward to use. Consider dropping...
From #371: Rather than the format ``` 1 1e-3 J1 ``` `photolysisConstant.config` should use the format ``` J1 1e-3 ``` and recreate the photo number from the name (removing the...
- [ ] Make sure that H2O and RH are mutually exclusive (if one is constrained or constant the other must be calculated). - [x] Make sure that the text...
JFAC is a scaling factor for the photolysis rates. It is the ratio between the measured and calculated photolysis rate of NO2 (jNO2 or J4) to adjust for cloudiness. If...
I am modeling a chamber experiment with a time step of 5 seconds and rates output step size of 5 seconds. The output in speciesConcentrations looks fine, concentrations change at...
There 2 main problems with the calculation of JFAC: 1. zeros or infinite values created by the division (see also #16). 1. different photolysis rates have different widths (due to...
Likely not a problem, but I am getting the following message. The model results look normal. gfortran version 4.9.2 ``` ------------------ Final statistics ------------------ No. steps = 181 No. f-s...
I am running the model with the following parameters: > **_2000 number of steps > 900 step size (seconds) > 2 species interpolation method (pw constant = 1, pw linear...
