Datasets for the comparison between POC estimated from BGC-Argo floats and PISCES model simulations

This dataset is composed of two main folders.

clim_3D: contains 4 files in 3 directories:

• BGC-Argo/bbp700_nemo_clim.nc: global monthly climatology of BGC-Argo b_bp700 measurements on the ORCA2_L31 NEMO grid.
• BGC-Argo/bbp700_nemo_climseas.nc: seasonal climatology (JFM, ...OND) of BGC-Argo b_bp700 measurements on the ORCA2_L31 NEMO grid.
• biomes/nemobiomes.nc: biomes of Fay and McKinley 2014 (ESSD) reprojected onto the ORCA2_L31 NEMO grid.
• PISCES/PISCES_1m_19600101_19601231_ptrc_T.nc: PISCES tracers (living organisms and detrial organic carbon), monthly climatology based on pre-industrial simulation described by Aumont et al. 2017 (Biogeosciences).

CATS_1D: contains 66 folders. The folders are named as <fwmo>_<yyyy>_<orca1cell>, where

• fwmo = World Meteorological Organization (WMO) float number
• yyyy = year
• orca1cell = number of the NEMO model horizontal grid cell (ORCA1 grid) used to run the PISCES 1D offline simulation.

Each folder contains:

• BGC-Argo observations for a given Argo float and year, bined onto the model vertical grid and 5-day peiods: 'Mprof*.nc'
• Dynamical fields used to run PISCES 1D offline simulations: 'dyna_grid_T.nc'
• Output of the simulations: PISCES tracers at 5-day resolution: 'PISCES_5d_*_ptrc_T.nc'
• List of horizontal model grid cells that were visited by the Argo float on a given year: 'xymatch_<fwmo>.csv'. If the list is queried for the grid cell number <orca1cell>, one can obtain the corresponding longitude (xmap), latitude (ymap), and the x and y indices of the grid (plus/minus 1). These indices correspond to the 3x3 horizontal grid of the dynamical fields and the PISCES 1D output.
