Click on the Binder button above to see how to access ASTE Release 1 output, using xmitgcm to create an xarray Dataset on the fly with dask. Calculations and visualizations are enabled by xgcm and ecco_v4_py.
Please see this web portal to download the output. Note that the output is distributed differently for matlab and python. The python demo above shows the horizontal ASTE grid as made up of 6 "tiles", where each tile is 270x270 grid points. The netcdf files listed below are split such that each file contains a single 90x90 tile, and 29 tiles make up the whole grid, see e.g. here. These 29 tiles are distributed across 5 "faces" which will be familiar to anyone who is familiar with the gcmfaces package for the LLC90 grid, see e.g. here.
