Perhaps "Fortunat's readme document" would clarify these issues, but I don't think I have a copy - please could someone forward one to me. A related problem is that the 7 simulations didn't come to me as separate files - at some point they were incorporated into one long email message as text. Given that the only distinguishing feature was their file names, I can no longer be certain which one is which - other than by comparing with the plots provided. Finally, if you want the forcings plotted as well as the NH temperatures, I will need the forcings. Previously we had them expressed as radiative forcing in W/m2, but separately for "volcanic", "solar" and "all other forcings", but perhaps here we just need a total forcing? Please advice. Plus, if we want a plot of the forcings, I will need the forcing time series. Perhaps these are also in "Fortunat's readme document"? Sorry for so many questions, Tim >>Date: Fri, 27 Jan 2006 16:46:40 +0100 >>From: Gian-Kasper Plattner >>Reply-To: plattner@climate.unibe.ch >>User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) >>Gecko/20030624 Netscape/7.1 >>X-Accept-Language: en-us, en >>To: Jonathan Overpeck >>CC: Fortunat Joos , >> Stefan Rahmstorf , >> Anders Levermann , >> Eva Bauer , >> Eystein Jansen , >> Keith Briffa , >> Christoph Raible >>Subject: Bern2.5CC IPCC-AR4 millennium simulations >>X-Virus-checked: by University of Berne >>X-UEA-Spam-Score: 0.0 >>X-UEA-Spam-Level: / >>X-UEA-Spam-Flag: NO >> >>Dear all, >> >>Please find attached the Bern2.5CC model output for the IPCC-AR4 >>millenium simulations, all spanning the period from 1000 - 1998AD. >>Some plots including a preliminary comparison between CLIMBER-2 and >>Bern2.5CC results are additionally included (see infos below). >> >>1.
