NASA POWER Access
Over 40 years of daily temperature, precipitation, humidity, irradiation and wind for any point on Earth — fetched directly, no account needed.
Climate analysis from NASA POWER. No code.
Analyze 40+ years of climate data directly in QGIS
Click a point on the map, fetch daily NASA POWER data, and explore annual trends, a thermo-pluviometric diagram and climate indices — all without leaving QGIS.
Core Features
A complete climate-analysis workflow inside QGIS, powered by the NASA POWER database.
Trend & Homogeneity Tests
Annual trend lines annotated with the Mann-Kendall trend test and the Pettitt change-point (homogeneity) test.
Thermo-pluviometric Diagram
The mean monthly precipitation and temperature regime of the location, on a clean dual-axis chart.
ETCCDI Indices & SPI
Seventeen ETCCDI temperature and precipitation indices plus the Standardized Precipitation Index for drought analysis.
Agronomic Variables
Reference evapotranspiration ET₀ (Hargreaves), growing degree days and 2 m wind speed — derived ready to plot.
Interactive Charts & Export
Plotly charts with zoom, pan and hover. Open any chart full-screen in the browser or export the data as CSV.
How It Works
Three steps from a map click to interactive climate charts.
Pick a point
Enable clicking mode and click anywhere on the map canvas, or type a longitude/latitude. Choose the year range.
Run the analysis
Click "Run analysis". ClimaPlots downloads the daily NASA POWER series and computes trends, the diagram and all indices in the background.
Explore & export
Browse the Trends, Thermo-pluviometric and Indices pages, open any chart in the browser, and export the data as CSV.
Getting Started
Install ClimaPlots and run your first analysis in minutes.
Install the plugin
Install ClimaPlots from the QGIS Plugin Manager, or download the zip from GitHub and use "Install from ZIP".
→ Download from GitHubFirst run sets up dependencies
On first launch the plugin downloads its scientific libraries automatically (one time). An internet connection is required.
Pick a point and run
Open the plugin, pick a location on the map, choose a year range, and click Run analysis. Behind a corporate network? Set a proxy on the intro page.
About the Project
ClimaPlots is a free and open project created to make long-term climate data easy to access and analyze inside QGIS. Supported by FARM Analytica, with a focus on solutions that connect technology and field intelligence.
