There is no such property stored at a specific location. The temperature is
a measure of the average speed [energy] of the atoms as a group.

No, they move faster when heated, and they move slower when cooled. Adding
energy [e.g., heat] to the collection of atoms adds energy to the atoms in
the collection (not immediately and identically to each atom, but over time
and in a distribution pattern according to the material in question and the
nature and location of the heat source). As each atom receives more energy
from the heat source, it speeds up. That is the "stored data"... it's
speed!

There is no temperature "of" a specific location. But your thermometer
takes up some space, and will interact with the atoms near it. The
collisions between those atoms and the atoms in the thermometer will cause
the thermometer to register a reading related to the energy imparted by
those collisions, thus giving you a reading of the temperature of the
substance, _in_that_vicinity_.

In the speed of the atoms themselves.
