  1. Confused, Perplexed, Bewildered About Yesterday? NCAR Climate Modeling Section certainly is! A lot of red marks, a few blue • inconsistent story with Collins’ broad brush summary • purpose of the next few slides is to illustrate ongoing sense of confusion • precipitable water • 200 mb temperature • 500 mb height field

  2. Precipitable Water CCM3 CAM CAM/CCM3

  9. PCMDI Analyses Important to engage broad segment of diagnostic community • extensive diagnostic breadth and experience in larger community • important to entrain expertise with evaluating model improvements • ability to concisely characterize model changes is a desirable goal Need to better understand merits of PCMDI synopses • important to understand the different messages coming from performance portraits • important to quantify the scientific content of single-number characterizations • especially important in the context of guiding model development activities
