DRI Gridded Data

DRI Gridded Data Repository. Work in progress. The idea with this repo is to develop a suite of tools to make working with large gridded datasets easier. This is outlined in the diagram below. The background colours represent the progress of the work. Green = Done, Yellow = Actively being worked on, Red = Not started.

workflow

The first product that we are developing is to allow for easy conversion of various gridded datasets to ARCO (Zarr) format and easy upload to object storage. This product is built upon pangeo-forge-recipes which provides convenience functions for Apache Beam, which handles all the complexity of the performant parallelisation needed for rapid execution of the conversion. For more information on the reasons and motivation for converting data to ARCO format see the README of the repository that generated the idea for this product.

Developer information

Product description document

Local installation

  • Download local copy of repository: git clone [email protected]:NERC-CEH/dri_gridded_data.git
  • Create a conda environment from the environment.yml file: conda create --name dri_gridded_data --file environment.yml

Running instructions

  • To run the netcdf --> zarr conversion script on your local machine: ipython scripts/convert_GEAR_beam.py
  • To run it on a SLURM-controlled HPC (such as JASMIN LOTUS): sbatch scripts/convert_GEAR_beam.sbatch

(editing the variables defined in the scripts as appropriate)
