Several users have reported erroneous temperature values in the Tmin-24h variable where the value for selected grid cells could reach unrealistic values of around 220 K (-50 C) in locations with otherwise high temperatures. Analysis of the spatial distribution demonstrated that the cells with erroneous values can often be found in Western Australia but are not limited to that region and can be found in other parts of the World as well (Figure 1).
