I need to understand some basics about atmospheric modelling, since I am working with data from the COSMO model for my thesis. My questions mainly concern model validation, like learning about the most common metrics to evaluate model accuracy. Therefore, does anybody have suggestions concerning good introductory textbooks for atmospheric modelling?
To clarify where I am coming from:
I am looking at regional climate data for the Antarctic as simulated by COSMO in Climate Mode driven by ERA-Interim. Observations in the region and for the period of interest are naturally sparse, so I wondered how I can validate the model data against the few observations there are. This led me to the question whether there are some general practices and statistical methods to validate output of an atmospheric model and hence the idea to ask for pointers to introductory textbooks.
