From: Ben Santer To: Steve McIntyre Subject: Re: FW: Santer et al 2008 Date: Mon, 10 Nov 2008 12:10:52 -0800 Reply-to: santer1@llnl.gov Cc: "Thorne, Peter" , Leopold Haimberger , Karl Taylor , Tom Wigley , John Lanzante , Susan Solomon , Melissa Free , peter gleckler , "'Philip D. Jones'" , Thomas R Karl , Steve Klein , carl mears , Doug Nychka , Gavin Schmidt , Steven Sherwood , Frank Wentz , Professor Glenn McGregor Dear Mr. McIntyre, I gather that your intent is to "audit" the findings of our recently-published paper in the International Journal of Climatology (IJoC). You are of course free to do so. I note that both the gridded model and observational datasets used in our IJoC paper are freely available to researchers. You should have no problem in accessing exactly the same model and observational datasets that we employed. You will need to do a little work in order to calculate synthetic Microwave Sounding Unit (MSU) temperatures from climate model atmospheric temperature information. This should not pose any difficulties for you. Algorithms for calculating synthetic MSU temperatures have been published by ourselves and others in the peer-reviewed literature. You will also need to calculate spatially-averaged temperature changes from the gridded model and observational data. Again, that should not be too taxing. In summary, you have access to all the raw information that you require in order to determine whether the conclusions reached in our IJoC paper are sound or unsound. I see no reason why I should do your work for you, and provide you with derived quantities (zonal means, synthetic MSU temperatures, etc.) which you can easily compute yourself. I am copying this email to all co-authors of the 2008 Santer et al. IJoC paper, as well as to Professor Glenn McGregor at IJoC. I gather that you have appointed yourself as an independent arbiter of the appropriate use of statistical tools in climate research. Rather that "auditing" our paper, you should be directing your attention to the 2007 IJoC paper published by David Douglass et al., which contains an egregious statistical error. Please do not communicate with me in the future.
