Plotted CH4 and N2O concentrations over time

[ptrscll]

Wrote script to plot historical and Hector CH4 and N2O concentrations over time. Let me know what you think of the plot @kdorheim

@ptrscll could you add the CH4 and N2O concentrations for the historical period from one of the input tables?

[ptrscll]

Just added in the data - it looks like it lines up exactly with the Meinhausen data (aside from 1750-1850 where the data's missing)

[kdorheim]

👍 okay great!

Alright, could you do the following historical runs

1. emission driven (baseline)
2. with [n2o] constraints only
3. with [ch4] constraints only
4. with [ch4] and [n2o] constraints only

I would like to see how far how much of an effect this has on global mean surface temperature

[ptrscll]

Just did those runs - there didn't seem to particularly large effect on GMST (at least relative to the changes with ECS):

Hmmm well that is good for past Hector things but a tad disappointing for us! Thanks for checking!
