pyeccodes

:warning: This is an experimental project: do not use in operations. The code has only been tested on a handful of GRIB files.

This is an experiment of a pure Python GRIB decoder based on eccodes. The code is automatically generated from the definition files and tables.

The package does not support encoding.

The difference with other Python bindings are:

• All arrays and lists are returns as numpy arrays
• Missing data values are set to numpy.NaN
• Asking for a missing key is not an error. The value None is returned
• If a key returns a missing value (e.g. 255), None is returned instead

You can use pyeccodes with cfgrib with a version greater or equal to 0.9.8.1.

Accessing data values:

from pyeccodes import Reader

reader = Reader("test.grib")

for grib in reader:
    print(grib.get('date'))
    print(grib.get('values'))

To get a list of all available keys:

from pyeccodes import Reader

reader = Reader("test.grib")
grib = next(reader)
grib.dump()
