High-level spatio-temporal analysis tools for Earth System data cubes
Because laziness is not only good when reading big data — it should apply to analysis too!
YAXArraysToolbox extends YAXArrays.jl with high-level functions for climate and Earth observation data analysis:
| Feature | Description |
|---|---|
| 📈 Time Series Plotting | Visualize temporal evolution with automatic spatial aggregation |
| 🗺️ Spatial Mapping | Create publication-ready maps with temporal aggregation |
| ⏱️ Temporal Aggregation | Resample data to monthly, yearly, or custom periods |
| 🔄 Space-for-Time Analysis | Estimate land cover change impacts on climate variables |
| 😷 Flexible Masking | Apply spatial, temporal, and altitude-based masks |

# Plot time series (spatial mean)
plot_time(cube; fun="mean")
# Create spatial map (temporal median)
plot_space(cube; fun="median")
# Aggregate to monthly resolution
monthly = aggregate_time(cube; new_resolution="month", fun="mean")Explore the full documentation at dpabon.github.io/YAXArraysToolbox.jl.
