Overview

cfdb-ingest converts meteorological file formats (netCDF4/HDF5) from various model outputs into cfdb. It standardizes variable names and attributes to be consistent with CF conventions, making it straightforward to work with datasets from different sources through a single interface.

Key features:

• Automatic variable mapping -- source variable names are translated to CF-standard names with proper metadata
• Wind rotation -- grid-relative wind components are rotated to earth-relative
• 3D level interpolation -- eta-level variables are interpolated to user-specified height or pressure levels
• WPS intermediate file export -- convert cfdb datasets to WPS intermediate format for metgrid.exe
• Spatial and temporal filtering -- subset by bounding box and/or date range
• Multi-file support -- seamlessly spans multiple input files

Installation

Requires Python >= 3.10.

pip install cfdb-ingest

Quick Start

from cfdb_ingest import WrfIngest

wrf = WrfIngest('wrfout_d01_2023-02-12_00:00:00.nc')
wrf.convert(
    cfdb_path='output.cfdb',
    variables=['T2', 'WIND10'],
    start_date='2023-02-12T06:00',
    end_date='2023-02-12T18:00',
)

cfdb-ingest wrf wrfout_d01_*.nc output.cfdb -v T2,WIND10 -s 2023-02-12T06:00 -e 2023-02-12T18:00

For WPS export, use the --preset wps flag:

cfdb-ingest wrf /path/to/wrfout/ output.cfdb --preset wps -s 2023-02-10 -e 2023-02-10_06
cfdb-to-int output.cfdb -s 2023-02-10 -e 2023-02-10_06
