<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Hi Rita,<div class=""><br class=""></div><div class="">the code cannot apply hflux/sflux with the sea ice model turned on, because the sea ice model computes these fluxes where there is ice. Frankly, what do you need the sea ice model for, if you want to prescribe the fluxes anyway? In this sense I’d support Dimitris’ suggestion. The fluxes that you prescribe should know about the sea ice distribution. It’s like prescribing the sea ice cover. If you want to have the sea ice modify these fluxes, more work is needed (and it will be complicated to get it “right”, i.e. consistent).<div class=""><br class=""></div><div class="">You’ll have to find a solution where you allow the model to compute the fluxes (from atmospheric fields that it reads) **and** read them. Depending what you want to do exactly I would have a look at pkg/exf and pkg/seaice and comment out the stop statements that bother you. Then you’d have to prescribe both the fluxes and the atmospheric fields and modify the code so that the fluxes are not overwritten by the ones that the exf-package computes. The sea ice model will then use the atmospheric fluxes (which you have prescribed) and recompute them in grid cells with sea ice. That could work, but I have never tried it.</div><div class=""><br class=""></div><div class="">Martin</div><div class=""><div><br class=""><blockquote type="cite" class=""><div class="">On 5.
