What problem does it solve?
GRIB2 data is dense and structured across multiple sections; this skill helps users understand, map, and access GRIB2 messages by exposing the core identity (parameter triplet), coordinates (level and time), and practical workflows for analysis.
Core Features & Use Cases
- Explain the GRIB2 file structure and how Section 4 encodes parameter identity
- Demonstrate mapping GRIB2 messages to a data-model (Variable/Band/Message) and using wgrib2 for indexing, matching, and extraction
- Provide lookup guidance via Code Tables 4.2 and 4.10, and handle common edge cases (local-use parameters)
- Offer practical workflows for analysts working with model outputs and observations to extract parameters for analysis, visualization, or archiving
Quick Start
Inspect a sample GRIB2 file and produce a concise mapping of each message to its parameter triplet, level, and time step, then follow with a basic wgrib2 indexing example.
