What problem does it solve?

This skill removes the heavy lifting of acquiring ERA5 climate reanalysis data and turning it into interpretable anomaly and trend results with publication-ready maps.

Core Features & Use Cases

• ERA5 data download via Copernicus CDS API: Pull monthly single-level or pressure-level reanalysis fields for chosen variables, years, and regions.
• Climate anomaly computation: Compute monthly anomalies relative to a configurable baseline period (e.g., 1981–2010).
• Grid-point trend analysis: Run pixel-wise Mann-Kendall tests with Theil-Sen slope estimation and produce significance masks.
• Cartopy visualization: Render global or regional anomaly/trend maps, optionally stippling statistically significant areas.
• Use case: Build an ERA5 temperature anomaly map and quantify where and when trends are increasing or decreasing for a region of interest.

Quick Start

Ask the AI to download ERA5 2-metre temperature for 1979–2023 globally, compute anomalies relative to 1991–2020, run Mann-Kendall trend analysis, and save a Robinson-projection anomaly map for a chosen year.
