Method & sources
A historical observation record
NASA POWER Monthly API, based on MERRA-2 reanalysis. Two requested sample coordinates near Esmeraldas and Cuenca, 2001–2025. Precipitation is an annual average daily rate in mm/day, not an annual total.
NASA POWER documentation ↗Visible statistical assumptions
Ordinary least squares estimates linear change per decade. Nominal 95% intervals use Student’s t with n − 2 degrees of freedom and assume independent, constant-variance errors. Serial correlation is not corrected.
Source & reproducibility ↗Spatial and statistical limits
The 0.5° × 0.625° grid is about 56 × 70 km near the equator. Samples are not city or province averages. Four exploratory location–variable comparisons; no multiple-comparison adjustment. Time windows affect the estimate.
