Computes mean NDVI and an ordinary least-squares daily NDVI trend, then applies yield = intercept + mean_coefficient×mean_NDVI + trend_coefficient×daily_trend. It does not derive NDVI from imagery, account for crop stage...
Combines caller-supplied AIS gap duration, unmatched satellite detections, night-observation fraction, and position discrepancy into a bounded score. It does not identify a vessel, link detections, establish illegal acti...
Uses da/dt = -rho×sqrt(mu×a)/ballistic_coefficient for a circular orbit, holds density and ballistic coefficient constant, and linearly projects altitude over a bounded horizon. Real density changes rapidly with altitude...
Propagates two caller-supplied Cartesian states with constant velocity, analytically finds the clamped time of closest approach, and compares miss distance with combined hard-body radius. It ignores gravity, covariance,...
Propagates a circular two-body orbit from altitude, inclination, RAAN, and initial orbital phase; rotates Earth at a fixed sidereal rate; and samples ground-station elevation. It ignores eccentricity, perturbations, epoc...
Maps a caller-supplied Kp value to conventional G0–G5 bands, maps Dst to declared disturbance bands, and combines severity with geomagnetic latitude and infrastructure class. It does not retrieve observations, forecast a...
Sums enhancement_ppm×pixel_area, multiplies by wind speed, plume orientation, and a caller-supplied conversion factor, and reports the resulting proxy and optional kg/h estimate. It does not retrieve satellite data, remo...
Treats cells at or above a caller threshold as foreground, labels four-neighbor connected components, and reports area, bounding box, peak, and mean value. It does not ingest imagery, calibrate backscatter, remove speckl...
Checks wind, gust, lightning distance, precipitation, cloud fraction, and temperature against caller-supplied limits and reports every failed rule. It does not retrieve observations, forecast weather, interpret vehicle-s...
Fits ordinary least squares to log radiance by year, converts the slope to annual radiance change, and applies a caller-supplied economic elasticity. Night lights are an imperfect proxy affected by sensors, saturation, e...
Provider identity is derived from the domain or repository in the source record. If two vendors share a host, they appear together here — that is a limitation of the data, not a statement about ownership.
