- The 49r1v4 includes all the land surface model updates including new vegetation : CY49R1 v-versions
- The tstep 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
