Visualizing and Comparing LIS Output


LIS Output Primer

LIS writes model state variables to disk at a frequency selected by the user (e.g., 6-hourly, daily, monthly). The LIS output we will be exploring was originally generated as daily NetCDF files, meaning one NetCDF was written per simulated day. We have converted these NetCDF files into a Zarr store for improved performance in the cloud.
