Preparation of Forcing Files

Forcing files are prepared with prepIFS generated using an IFS CY43R3 experimentIFS CY43R3 experiment h7z9. The IFS experiment is set up for nudged configuration and the inigroup process family will extract ERA-Interim analyses from MARS and generate forcing files. 

Select start date and run length to produce forcing files. Adjust INIBEGINDATE, INIENDDATE and INITIME to reflect the start date (first day of the month), e.g. 2013070100. FCLENGTH should be set to 744 for one month or to 1488 for two months of forcing files to be created.

For every 6-hour period one gridpoint and one spectral forcing file is created from ERA-I analyses, at T255L60 reduced linear Gaussian horizontal grid. 

A local copy of scripts branch damk_CY43R3_getrelax is required which copies the forcing files from the fws working directory to $SCRATCH/rlxml/. At present directory rlxml must exist in the user's scratch space with 777 writing permissions.
