This *.zip file contains the model output from seasonal variability experiments using the NPZD-DOP GEOMAR biogeochemical model (Kriest et al., 2010) coupled with the MITgcm 2.8deg ocean circulation via the transport matrix method (Khatiwala et al., 2005; Khatiwala, 2007; Khatiwala, 2018). These model outputs are presented and discussed in the Preprint "Seasonality in carbon flux attenuation explains spatial variability in transfer efficiency", published by Geophysical Research Letters (de Melo Viríssimo et al., 2024). The manuscript describes the experiments performed, the parameter values used and the modifications done to the original model. For this matter, we also refer you to de Melo Viríssimo et al. (2022). All files uploaded were generated from simulations run by the authors, except: the grid file, the salinity field, and the temperature field, which came with the model; and the density fields, who were computed from the MITgcm 2.8deg transport matrix by Dr Rafaelle Bernadello, using a TEOS-10 Matlab routine (http://www.teos-10.org/). For specific information about each file uploaded, please refer to the README file. If you have any questions, please feel free to contact me.
