Landmodels

• Use a site represent a scenario
• Put all together
• Latitude trend, mismatch at south and north ~50 degree, different projection?
• Have a meet with Will on Wednesday talking about the spatial mismatch.

Surrogate

• Re-submitted the revision

Now I think I understand what's going on with the zonal plots.

Previously I'd just looked at zonal plots of GPP, which are coming from CLM4.5 in these simulations, and seemed reasonable. It looks like the CASA land model has really high autotrophic respiration rates in the tropics, which accounts for the odd distribution in zonal mean plots that you're seeing, Jinshi.

I plotted up a single year's data in this notebook (which doesn't always like to render...)

• Why high Ra in the tropics can explain the odd zonal mean plots of Rh in the North ~50 degree?
• From Figure 3 of GCB paper “Carbon cycle confidence and uncertainty: Exploring variationamong soil biogeochemical models”, I see a peak of SOC at ~ 50 degree north, so I assume if SOC was considered in the statistic models, the peak at ~50 degree should be higher than it was.
• What is the relationship between CMIP6, CASA-CNP, CORPSE, and MIMICS?
• ~1000 zero Rh outputs from CASA-CNP, CORPSE, and MIMICS.
• Can CASA-CNP, CORPSE, and MIMICS run at site level?

This is the final week for you to submit abstracts to this year’s Postgraduate Research Symposium, they are due this Friday, June 26! Abstract resources and submission information can be found here: https://pnnl.cvent.com/postgrad2020.

Notes for meeting on 6/23

1. Whether it is necessary to run CASA, CORPSE, and MIMICS at the site level (for those 258 sites have field measured RH);
2. A diagram showing how CASA, CORPSE, and MIMICS were set up, and get the daily RH? or can just refer to Figure 1 of (Wieder et al., 2017) GCB paper?
3. Target Journal suggestions: Nature Geoscience, GCB, GBC, GRL.
4. Abstract for PNNL postdoc Symposium (deadline is June 26th to submit).
5. Zonal map (RH is overestimated at North ~50 degrees or overestimated at the equator?)
6. Benchmark: SOC not included in the statistic model? See Wieder et al. 2017 GCB paper.
