Code:



1] ColdPoolSali_MeanAdvectionOffline.m



Task: Computes mean advection fluxes for salinity flux budget as outlined in section 2.3 of accompanying manuscript

Input: NESS model output from Chen et al. (2022)



2] ColdPoolSali_ControlVolumeAvg.m



Task: Computes budget flux terms, averaged across a cold pool control volume outlined in section 2.3 of accompanying manuscript 

Input: Mean advection fluxes produced by "ColdPoolSali_MeanAdvectionOffline.m" + NESS model data from Chen et al. (2022)

Output: "ColdPoolSalinityBudget_Fluxes_v1.mat" (provided in folder "Data")





3] ColdPoolSali_CrossShelfTransect.m





Task: Provide NESS-model output along a meridional cross-shelfbreak transect along 70.875°W on an equidistant time-depth-latitude grid

Input: NESS model data from Chen et al. (2022)

Output: "ColdPoolCrossSection_Fields_v1.mat" (provided in folder "Data")




4] ColdPoolSali_MakeFigures_v3.m
