Geomet Catalog

claude-geomet-skill

A Claude Code plugin that provides access to Environment and Climate Change Canada's open data through the MSC GeoMet OGC API. Browse, query, visualize, and export Canadian weather, climate, hydrometric, and air quality data -- all from within Claude Code.

Installation

/plugin marketplace add sfoucher/claude-geomet-skill
/plugin install geomet-catalog@claude-geomet-skill

Quick Start

Once installed, the skill triggers automatically when you ask about Canadian weather or climate data. Here are some example prompts:

Search for climate collections on GeoMet

Fetch the last 20 hourly temperature readings from Ottawa

Export daily climate data for Toronto area (June 2023) to CSV

Plot a time series of temperature from climate-hourly for Ottawa
