SRDB updating

• Meeting twice with Hope, go through 2 additional papers
• Assigned her one 2018 paper, will do the real data collecting practice (similar as Jason and Darlin), Hope will collect data into srdb, I will check her inputs, and Hope, Stephanie, and me will discuss this Wednesday.

Soil erosion (ESSD)

• According to the similarity report, did some changes and resubmitted

Land model

• Deadline for last round of comments is this Thursday

RC partitioning

• Tang have shared me the N-deposition data, will work on this project this week

Global C

• Updated to SRDB-V5

• Kalyn will work on updating CMIP6 results

• Rs(lit) is ~ 85 Pg, possible errors including: 1) Collar insertion 2) Monthly variability 3) Sites spatial uneven distribution 4) Measure frequency (from SRDB, the average is ~once a month), we can use COSORE to quantify the error of once per month? 5) Measure window (measured at day time, the average is 9-12 ?), we can use COSORE to quantify this error?

• We can also use MGRsD to estimate mean monthly Rs for the global (i.e., we will have a global Rs estimate for Jan - Dec), and then get the global annual Rs

• In this way, we do not have the error for 2), 4); but still need to consider error for 1), 2), and 5)

And finally, we want to see whether global annual Rs with error considered is closer to Rs(gpp)

I don't know whether we can (or is it necessary?) do a similar thing for GPP(lit)

Also note we have slides due to Vanessa later this week.
