Trend Check: is it really changing?

Trend Check reads 16 measures: thirteen NASA POWER monthly records from 1981, including air temperature, rainfall, soil moisture, humidity, wind, sunlight, cloud cover, haze and the ozone layer, plus NASA GPM IMERG rainfall and GLDAS soil water and runoff from 2001. Every rainfall trend is also checked against NASA's other rainfall records over the same years.

Each check removes the seasonal cycle, measures the change per decade with a 95% interval that allows for month-to-month memory, and confirms it with a seasonal Mann–Kendall test. Compare up to six places with a correction for testing many places at once.
