2 1/2 papers on engineering climate models

Here are two papers (plus another that goes into more depth) on the software engineering of the Community Climate System Model, and the Earth Systems Modelling Framework. I'm just starting to get into these projects, and these papers have been very helpful so far:

1. Overview of the Software Design of the Community Climate System Model by J. Drake et. al.
   This paper describes the dreamy world of the CCSM project, a seemingly well-oiled software engineering enterprise. This paper covers the design of the CCSM, plus an overview of the software development process.


2. The Architecture of the Earth System Modeling Framework by C. Hill et al.
   This is a larger project that incorporates the CCSM. This paper just outlines the design (no process). For more details see: Design and Implementation of Components in the Earth System Modeling Framework by N. Collins et al.
