Benchmark plots

This is the first GEOS-Chem benchmark to utilize GCPy. Some benchmark plots created by GAMAP still remain because they have not been recreated in GCPy yet. To view the entirety of the old version of benchmark plots created by GAMAP, visit http://ftp.as.harvard.edu/gcgrid/geos-chem/1mo_benchmarks/GC_12/12.3.0/output/.

3Zonal mean vertical axis: The zonal mean vertical axis is currently model level, but work is in progress to change it to pressure. To view the old plots created in GAMAP with pressure as the vertical axis, visit the following links: zonal mean maps and zonal mean differences

NOTES:

  1. Category and lumped species definitions are simple to adjust. Updating them requires only editing the json files.
  2. All plots created with GCPy have PDF bookmarks. If you do not see them in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.

Comments on SURFACE differences: Below we summarize the notable changes caused by specific updates.

Update ISORROPIA from v2.0 to v2.2

  • This update caused changes in NH3 and NIT at all levels. These differences are small number differences where concentrations are low.

Updated PFT file for MEGAN

  • This update caused changes in the primary and secondary organic species. Percent differences are largest over the oceans, where concentrations are low.

OMI-based Volcanic emissions 1979-2018

  • This update caused large decreases in SO2 over and downwind of volcanic regions. This also impacted SO4, SO4s, NH3, NH4, NIT, NITs, HNO3, several bromine species near those regions. Cui Ge wrote:
I saw the non-eruptive volcano emission in July of 2016 seems 0 everywhere. If the NASA online data shows this, I think it is OK to be consistent with that.

Thanks for confirming this data includes both explosive and effusive eruptions. By my understanding, because volcano emission has big uncertainty (from literature also from our volcano paper), NASA team did some adjustment (the amount of volcano emission, the duration of each volcano, etc) after we published our paper. I think this updated volcano data would be the best volcano data we have for now, also we may want to keep our data to be consistent with this online source data. The AEROCOM volcano data (used in GEOS-Chem) has much bigger uncertainties. To summarize this, I think the code, the process and the data what you are using is all right. As long as we have consistent volcano data with this online source, it would be great.

The following updates impacted species concentrations slightly, but the changes did not amount to >10%.
