Cache observations
NASA POWER and MODIS observations are cached before analysis; missing records never become estimated values.

NASA Space Apps Challenge 2026
NASA Space Apps Relationship
MEC TERRA_DETECTORS built TerraBangla for the NASA Space Apps Challenge 2026 challenge, ‘Be An Earth System Trend Detective!’. It turns NASA Earth-observation records into explorable climate evidence for all 64 districts of Bangladesh—without inventing missing values.
