The 49r1v4 includes all the land surface model updates including new vegetation : CY49R1 v-versions
The tstep(=1200) is the same as the atmospheric model used for the extended-range and seasonal forecasts in the latest configurations.
The period from 1968 to 1969 : spin-up for the land surface model
