Data & Methods

Every number on this site is computed from cached NASA observations. Trend significance uses the Mann-Kendall test; the rate of change uses the Theil-Sen estimator. No number is ever produced by a language model, and locations without cached data say so instead of showing estimates.

76 / 326 locations currently have cached time series.

Worldwide country and city searches load NASA records for 2015–2024 at the selected coordinate. Samples are not national averages. POWER annual values require 12 valid months; MODIS annual values require at least 8 valid composites. The original Bangladesh boundaries and caches remain available as regional evidence.
