Longitudinal variations of hmF2 are so strong and their extrema at certain longitudes are so stable that they are clearly seen even in maps established after averaging a great number of measurements at different times.
The average EEJ current density distribution for noontime conditions derived from CHAMP measurements show large diurnal variations occurring at certain longitudes, example, at 90° W and 90° E (Luhr et al. 2008).
They restarted the watches based on Nansen's guesswork that their longitude was 86°E, but the pair were no longer certain where they were.
Therefore, this paper proposed a GeoHash algorithm to implement this step: through a certain rule [12, 13], a string to represent the latitude and two longitude coordinates.
However, for a certain environment class, the evolution of μ w and σ w with respect to the longitude does not seem to be consistent, as shown in Figure 12.

This Watch Knows Longitude and Latitude.
Simple longitude could also be key.
Longitude 131 guests get a subtler experience.
16 min. N., longitude 50 deg.
