Calibrate Temperature | Option or Algorithm
-
We all (almost all) know that the temperature offered by the temperature sensors of suunto watches (among other competent brands) uses the barometer or other and that, in reality, what it picks up is the body temperature.
I wish there was an option to balance the temperature or that an algorithm is able to distinguish the difference between the body temperature (when the watch is close) and the one outside (air temperature). Or simply that we can calibrate it, assuming that if you do not give the air to the clock is +4ºC - +5ºC of the original (except if there is air that makes this temperature more real to the outside environment).
Just as we have the option to balance the barometric pressure, it would be nice to have one of the 2 options above. i hope support and thanks!

@gabpr05 This would be a nice feature to have. So far, the temperature data with the watch worn during activities is erroneous and doesn’t offer a lot of useful in-activity or post-activity value. So it’ll be great to someday improve this metric.
The challenge here is that barometric data is a simpler/linear adjustment of the barometer value relative to sea-level. Whereas with temperature, we have the issue of accounting for the thermal boundary layer that forms around the skin. That boundary layer would affect heat transfer around the watch and would have different behaviour in a breeze, while running, while stationary. Even if the watch is solving partial differential equations every instant, without accurate conditions about the skin temp, air flow, air temp, humidiy and other steady state conditions, it would be erroneous as well. E.g. the difference might be +2C with a headwind, +4C with a tailwind, etc
Perhaps a skin-thermometer built-into a future watch allows a better real-time error-correction of the temperature. Maybe that allows capturing parameters to model the boundary layer around the skin and how it might be affecting the air temp.
Here are some other thoughts and questions:
What is the function of showing temperature?
- In-activity: Identifying minimum temps to protect from windchill and frost-bite conditions
- In-activity: Identifying maximum temps to protect from overheating (should be body temp instead of air temp?)
- Post-activity: Analyzing of the effect of atmospheric conditions on our activity physiology.
- What else would you add?
Imported in-run weather data
If the watch has sync’d the recent weather data, then displaying that value as a selectable value on the watch (similar to the S+ app) would be meaningful. This would be a general value for the region and not actual temperature felt in the bubble around us.Post-run weather data
If we could use historical weather data in the Suunto App (similar to the one by Klimat app integration), the temperature curve for an activity would be more meaningful. -
@gabpr05 why to Balance the barometer?! Didnt sound good. You dont have to calibrate the barometer Sensor. But you can correct the level above sealevel.

As part of calibrating the barometric altimeter, the temperature of the sensor is required as part of the calibration as pressure is also temperature dependent
