Beta = 0.36 seems incorrect, isn't it 0.53. beta <- fetchvars(core, NA, BETA()) beta ## scenario year variable value units ## 1 Unnamed Hector core NA beta 0.53 (unitless) (...) The current value is set to 0.36 (note that it is a unitless quantity, hence the (unitless) unit).
Fix a minor numeric inconsistency in the hector vignette
* Github Issue 718. Add papers to Hector manuscript lists, including V3.2.0 manuscript * github issue 727. rename FCH4 to RF_CH4 to match all other RF output * Add a new release checklist * github issue 734, add output streams * quite build message * github issue 740, add matilda refernces * github issue 735, add ref temperature period to plot
Fix permafrost refreeze typo
Expose soil and detritus RH fluxes as possible Hector outputs.
Here we change where the scalers are applied so that the vol, aerosol, and total forcing outputs are updated appropriately. While this PR does not change hector output or behavior between the parameter name change, there are code-breaking changes that have been made to the ini files. The ini files are not backward compatible. --------- Co-authored-by: ptrscll <[email protected]>
Ensure 0 forcing in the volcanic input time series during Hector's reference period. Update the old-new test data, as this change affects the total RF and global temperature.
* reformat R code base using stylr and other changes to pass R unit testing * add ALL_VARS function that can be used to fetch all of the Hector output variables in R
1. Update methane lifetime parameter Tsoil and Tstrat. 2. Update the coefficients used in the tau OH equation. 3. Time-varying natural CH4 emissions 4. Update old-new comparison data
* simplify the input csv data tables * add P. Scully to the author list * clean up get units function
Update the default values of q10_1h, beta, and diff by calibrating Hector to historical observations.

Compared with Hector V3.2.0, the V3.5.0 version has less heat uptake by the ocean, resulting in higher mean air temperature. 
Due to changes in parametrization, the V3.5.0 has lower CO2 concentrations. 
The changes in natural N2O and CH4 emissions, as well as the CH4 lifetime parametrization update, also cause these concentrations to change.

"new default diff, beta, q10_rh parameter values based on recalibration against X"? |

@bpbond, regarding your question of how these changes affect Hector's alignment with historical observations
