windgrib 1.0.1

A Python package for working with GRIB weather data files

WindGrib

A Python library for downloading, reading, and processing meteorological data in GRIB format.

🌍 Overview

WindGrib focuses on efficient wind data extraction and targeted variable downloading from meteorological models. Key features include:

• Subset-Based Downloads: Download only specific variables using GRIB index files
• Automatic Latest Data: Retrieves the most recent available forecast data
• Smart Caching: Intelligent caching with incremental download completion
• Multi-Model Support: GFS Wave, ECMWF IFS, and custom model definitions
• AWS S3 Focused: Specifically designed for meteorological data hosted on Amazon S3
• High Performance: Asyncio-based downloads and parallel GRIB decoding for maximum speed

🚀 Installation

pip install windgrib

📈 Basic Usage

from windgrib import Grib
import numpy as np

# Download GFS wind data
gb = Grib(time='2026/01/3', model='gfswave')
gb.download()

# Access wind data
wind_data = gb['wind'].ds

# Calculate wind speed
wind_speed = np.sqrt(wind_data.u**2 + wind_data.v**2)
print(f"Average speed: {wind_speed.mean().values:.2f} m/s")
