Dear all,
please allow me to quickly introduce myself: I'm Christoph
Müller, working at the Potsdam Institute for Climate Impact
Research in Potsdam, Germany. I'm modeling crop growth and yield at
the global scale for about 2 decades and also co-coordinate the
Global Gridded Crop Model Intercomparison (GGCMI) in AgMIP (Agricultural Model
Intercomparison and Improvement Project).
I'm reaching out to you, as the global-scale modeling has helped me
to better understand the breadth of uncertainties from models
(equations and parameters and user choices) leading to the
hypothesis that crop models cannot be sufficiently evaluated by
comparing to historical yield variation. Instead, we need more
testing on functionality, common senses etc.
In order to make this a useful exercise to all, model developers and
model users and science in general, I do ask all of you to take a
little bit of your time to contribute ideas on what kind of test
models should be exposed to (thanks!):

You input is very valuable, also if you're not a crop modeler
yourself.
You can of course also directly reach out to me, but I hope that the
survey will help organizing feedback.
Don't hesitate to ask if you have any questions.
Your input is greatly appreciated.
Cheers!
Christoph
