A
The time of day when soil, water, and concrete thermal radiation are nearly equal.
1
Q
What is MRT?
A
Minimum resolvable temperature is the lowest equivalent thermal difference between an object and its background that can be resolved, or seen, by an observer through a FLIR System.
2
Q
IR crossover: what crosses over and what doesn’t?
A
Crossover for soil, water, and concrete usually occurs twice in 24 hours; soil and concrete do not crossover with vegetation; however, vegetation and water do crossover.
