Trend Detective
One cause can push two measurements in opposite directions.
Both records, year by year
Annual means, each on its own axisHow tightly linked?
Does one lead the other?
Does the second record follow the first, 0–6 months later?
About EarthScope
Is the change real, and how big is it? EarthScope answers that from open NASA data. Made for NASA Space Apps 2026.

Datasets
Trend and significance
1. Test. Months become yearly averages. The Mann–Kendall test asks whether they keep rising or falling.
2. Correct for memory. Wet years follow wet years. We widen the test for that, so memory doesn’t pass as a trend.
3. Measure. Sen’s slope gives the rate, with a 95% range.
4. Map. Benjamini–Hochberg keeps false alarms near 5%.
Forecasts
Ensemble. Five models forecast each record. Each is tested on years it never saw.
Skill gate. A model that can’t beat the recent average is dropped.
Ranges. The bands come from how wrong past forecasts were.
Beyond ten years. A trend line can’t see 2100. NASA’s climate projections can. They’re next.
Limits
- Vegetation and rain start in 2010. Sixteen years is short.
- MODIS is retiring. VIIRS can take over.
- Two trends moving together suggest a cause. They don’t prove one.
- Rain data is weaker over snow, mountains and coasts.
