The lowest recorded temperature on Earth is -89.2 celsius at ground level. Why does the data says it's -96 celsius 2m above ground and -99 celsius above ground? Since this is most likely an incorrect estimation, does this mean other things will be incorrect? I think when something is record-breaking, questions about reliability should be asked.
Tenki The exact same value is in the data directly from the model (177,6 K is -96 °C). See attached raw data. The model just calculates it. It's only displayed on Ventusky. We do not modify model calculations.
In this situation, it is difficult to model the temperature and also to measure it. The air here is extremely dry and the conditions are extreme (incomparable to the rest of the world).
The number of stations at a given location affects the accuracy of the model. There are a minimal number of stations in Antarctica, making it hard to determine the accuracy. The conditions are likely different there, as temperatures can change by 30°C in a few hours. It’s a different world.
