bbc_long_12 Description

As bbc_long_11 (corrected 3.6Ma bbc_long) but with no ice sheets changing (but orbit and GHGs). It is using the latest version with improvements to atmospheric convection and land surface which improves the simulation of the N. African monsoon system (and also the East Asian monsoon). It uses the latest setup of HadCM3BB (as of May 2022), including a number of small bug fixes etc. It is forced with changing greenhouse gases, ice sheet from DeBoer et al 2013, and corresponding ocean salinity. Each simulation is 500 years, initialised from the nearest bbc_long_04 simulations. Simulations are every 4kyr from 3600kyr to 24kyr, after which they are 1kyr BP intervals. Extensive output.
