How can the maximum temperature (tmmx) band in the TerraClimate GEE dataset be interpreted?

Question

This question was already asked here. But there was no correct answer. link
I'm using the precipitation, maximum temperature (tmmx) and soil moisture in the TerraClimate dataset in GEE. I cannot find out how to interpret the tmmx values. I have looked into the literature Link Link Link, but couldn't find what these numbers exactly mean.
The tmmx is based on the WorldClim dataset and is apparently "average maximum temperature (°C)"
The range is between -670°C and 576°C (globally) Link.
Gridded TMN and TMX are derived from gridded TMP and DTR according to:
TMX = TMP + DTR/2 Link in appendix 3
My ideas are: 1) it is some other unit (Fahrenheit or Kelvin)(but they say it's in °C)
2) it is accumulated (but nowhere on earth the max T adds up to -670)
3) it is accumulated in another way (temporal or spatial) which leads to these numbers
This is how it looks in GEE for central Europe:

If you look at the bands table, you'll see there's a scale column. The scale for tmmx is 0.1. That means the actual temperatures vary between about -670 * 0.1 °C = -67.0 °C and 576 * 0.1 °C = 57.6 °C.
