The WRF model physics do not predict sea-surface temperature (SST), vegetation fraction, albedo, or sea-ice. For long simulations, the model provides an alternative to read-in the data and update these fields. In order to use this option, you must have access to time-varying SST and sea ice fields. Twelve monthly values of vegetation fraction and albedo are available from the geogrid program. Once these fields are produced via WPS, you can activate the following options before running real.exe and wrf.exe:

sst_update =1
auxinput4_inname = "wrflowinp_d"
auxinput4_interval = 360, 360, 360
