| committed climate change experiment | Commit | Run 1 | 2001 | 1 | 2100 | 12 | 20C3M Run 0 | 2001 | Run 0 (not sent to PCMDI) is exactly the same as RUN 1 until year 1970, then it differs because of a bug reading the file of sulfate from year 1970 to 1975. We verify that the climate of year 2000 of RUN 0 is very close to climate of year 2000 of run 1. | |
