pangeo-forge-cmr

Small library that integrates NASA's Common Metadata Repository (CMR) with pangeo-forge-recipes. The goal is to help make pangeo-forge recipes that use CMR for getting raw data.

Installation

You can install this from PyPI with pip install pangeo-forge-cmr.

Example

from pangeo_forge_recipes.patterns import pattern_from_file_sequence
from pangeo_forge_recipes.recipes import XarrayZarrRecipe
from pangeo_forge_cmr import get_cmr_granules_links

# Get the GPM IMERG Late Precipitation Daily data
shortname = 'GPM_3IMERGDL'

recipe = XarrayZarrRecipe( # We are making Zarr, could be something else too
    pattern_from_file_sequence(
        get_cmr_granules_links(shortname), # Provide a list of files by querying CMR
        nitems_per_file=1,
        concat_dim='time',  # Describe how the dataset is chunked
    ),
    inputs_per_chunk=12,
)
