Note the last bit with the weather report: https://brr.fyi/media/sunset/weather-data.png https://brr.fyi/media/sunset/weather-data.png The station is at 10,657 feet (it's on top of a mountain) and the air pressure is 679.1 mb. Though https://en.wikipedia.org/wiki/Dry_ice#/media/File:Comparison_carbon_dioxide_water_phase_diagrams.svg https://en.wikipedia.org/wiki/Dry_ice#/media/File:Comparison... is a log chart for y and doesn't have many minor ticks for X ... I want to say it's closer to -83 °C. It's significant enough that you'd notice (if you were to go outside).
