McIntyre asked for "Monthly average T2LT values for the 47 climate models (sic) as used to test the H1 hypothesis in Santer et al., Consistency of modelled and observed temperature trends in the tropical troposphere". I was made aware of the FOIA request earlier this morning. McIntyre's request eventually reached the U.S. DOE National Nuclear Security Administration (NNSA), Livermore Site Office. The requested records are to be provided to the "FOIA Point of Contact" (presumably at NNSA) by Dec. 22, 2008. McIntyre's request is poorly-formulated and misleading. As noted in the Santer et al. paper cited by McIntyre, we examined "a set of 49 simulations of twentieth century climate change performed with 19 different models". McIntyre confuses the number of 20th century realizations analyzed in our paper (49, not 47!) with the number of climate models used to generate those realizations (19). This very basic mistake does not inspire one with confidence about McIntyre's understanding of climate models, or his ability to undertake meaningful analysis of climate model results. Over the past several weeks, I've had a number of discussions about the "FOIA issue" with PCMDI's Director (Dave Bader), with other LLNL colleagues, and with colleagues outside of the Lab. Based on these discussions, I have decided to "publish" all of the climate model surface temperature time series and synthetic MSU time series (for the tropical lower troposphere [T2LT] and the tropical mid- to upper-troposphere [T2]) that we used in our International Journal of Climatology (IJoC) paper. This will involve putting these datasets through an internal "Review and Release" procedure, and then placing the datasets on PCMDI's publicly-accessible website. The website will also provide information on how synthetic Microwave Sounding Unit (MSU) temperatures were calculated, anomaly definition, analysis periods, etc. After publication of the model data, we will inform the "FOIA Point of Contact" that the information requested by McIntyre is publicly available for bona fide scientific research. Unfortunately, we cannot guard against intentional or unintentional misuse of these datasets by McIntyre or others. By publishing the T2, T2LT, and surface temperature data, we will be providing far more than the "Monthly average T2LT values" mentioned in McIntyre's FOIA request to DOE. This will make it difficult for McIntyre to continue making the bogus claim that he is being denied access to the climate model data necessary to evaluate the validity of our findings. All of the raw model output used in our IJoC paper are already available to Mr. McIntyre (as I informed him several months ago), as are the algorithms required to calculate synthetic MSU temperatures from raw model temperature data. I hope that "publication" of the synthetic MSU temperatures resolves this matter to the satisfaction of NNSA, DOE Headquarters, and LLNL.
