Viticulture, microclimate on every plot
Cold air pools at the bottom of the slope. Without plot-level measurement there is no way to know where.

In a vineyard on a slope, the minimum temperature between the top of the hill and the base can differ by several degrees on clear nights. Stations on separate plots show exactly where the cold air collects and where the soil dries out first.
The minimum-temperature alert arrives by email before the critical threshold, and the per-plot history of rainfall and soil moisture is what irrigation and canopy-work decisions are built on.
Through the season, vapour pressure deficit and dew point complete the picture: the first shows how hard the vine is transpiring, the second how long the leaf stays wet, the window in which disease pressure rises.
