ClimaPlots

Climate analysis from NASA POWER and Open-Meteo (ERA5), inside QGIS.

ClimaPlots fetches decades of daily climate data for any point on the map and turns it into interactive charts — no coding required. Choose between two data sources: NASA POWER (from 1981) and Open-Meteo (ERA5) (from 1940).

What it produces

Annual trends for temperature, precipitation, relative humidity, irradiation, wind speed, reference ET₀ and growing degree days, each annotated with Mann–Kendall trend and Pettitt homogeneity tests.

Thermo-pluviometric diagram — the mean monthly precipitation and temperature regime of the location.

Climate indices — ETCCDI temperature and precipitation indices plus the Standardized Precipitation Index (SPI).

Compare two locations or two sources

Add an optional comparison point B to overlay a second series on the Trends chart, with trend statistics reported for both points. B can use its own data source, so the same location can be compared across NASA POWER and Open-Meteo — use Same location as A to copy point A's coordinates without re-clicking the map.

Quick start

1. Open the Coordinates page and pick a data source.
2. Click Pick point on map and click a location on the canvas (or type the longitude/latitude manually).
3. Optionally set a comparison point B — pick it on the map, or press Same location as A.
4. Press Run Analysis and wait while the data is downloaded.
5. Browse the Trends, Thermo-pluviometric and Indices pages. Use Open in the browser for a full-screen chart, or Save data to export a CSV.
