GRIB2 Format

Read GRIB2 meteorological messages as dictionaries (one message per record).

Record shape

Backend-dependent. Records always include shortName and values. With cfgrib, coordinates such as time, step, level, latitude, and longitude may also appear.

Backend preference: cfgrib (+ xarray) → pygrib → eccodes. All messages are loaded into memory; a filename path is required.

Usage

from iterable import open_iterable

with open_iterable("forecast.grib2", format="grib2") as source:
    for msg in source:
        print(msg["shortName"], len(msg["values"]))

Install with pip install iterabledata[geophysical].
