Dear Forum,The namelist options SSTICE_YEAR_ALIGN, SSTICE_YEAR_START and RUN_STARTDATE, could they serve to generate AMIP ensemble members?Say if there's 100-year (1900-1999) SST and ice for AMIP run, one can somewhat generate ensemble members by setting:RUN_STARTDATE=YYYY-01-01SSTICE_YEAR_ALIGN=YYYYSSTICE_YEAR_START=YYYYwhere YYYY is 1900, 1901, 1902 ... If only 1950-1999 period is of interest.Is the above way in generating ensemble members correct? Another question is, if the above method is correct, skipping one year for each ensemble member wastes a lot of resources if SST has fewer years.Say if there's 50-year (1950-1999) SST and ice for AMIP run, and one would like to generate ensemble members by beginning with each month, instead of a year:RUN_STARTDATE=1950-MM-01SSTICE_YEAR_ALIGN=1950SSTICE_YEAR_START=1950where MM is 01, 02, 03 ...In this case, the SSTICE_YEAR_ALIGN and START is set to the same year, but RUN_STARTDATE doesn't start from the beginning of the year.What will the model do under this condition? Will the model provide 1950-01-01 SSTICE for 1950-06-01 atmosphere?Thank you
