The following is a summary of processed model output data from a series of HiLAT model runs. A description of the model runs and visualization of model output and analysis can be found in the accompanying manuscript. Gibson, G.A., Weijer, W., Jeffery, N. and Wang, S (2020) Relative impact of sea ice and temperature changes on Arctic marine production. Journal of Geophysical Research: Biogeosciences. DOI:10.1029/2019JG005343 The model outputs and accompanying research was supported by the National Science Foundation 173886 and by DOE | SC |Biological and Environmental Research (BER). There are 4 versions of most output file types, corresponding to the 4 experiments that were conducted. These experiments are: i) the baseline model simulation (Base); ii) a moderate ice reduction experiment (S1); iii) a dramatic ice reduction experiment (S2); and iv) an atmospheric warming scenario (RCP45). Each of the 4 experiments is described in detail in Gibson et al (2020). Many variables in the output files are regional averages where model regions are indicated by a number *note - for aesthetics, the numbering used in the model output files differs slightly from the numbering used in the accompanying manuscript.

The unmodified NCEP forcing is freely publically available elsewhere to not duplicated here Ice Ice-Regional-Monthly-177-186-*.nc where * indicates model run - Base, S1, S2 or RCP45.
