Model Simulations

Experiment: temma

This is a continuation of temaa except that (a) the mass of the atmosphere has been corrected to the same as the control. and (b) we are not longer using the salinity conservation update but instead using a revised waterfix.

This job is a standard version of HadCM3M2.1D (dynamic TRIFFID) based on tdaae. However, it has a number of small additions/changes. These include: (1) the dark_respiration update is included, (2) the orbital update as in FAMOUS, (3) salinity conservation is included, (4) age of water tracer included. One executable can be used for all time periods

The boundary conditions are (a) GLAC-1D, used in anomaly mode, (b) GHGs from the latest estimates, (c) global salinity approx 1PSU more at LGM and scaled with sealevel for other periods (d) orbital changes via FAMOUS update (default is Berger and Loutre 1991)
