Hi!

I tried to calculate PET with the microclimate data in a place where have a moderate climate. however , the calculation result is extremely high.
For example, the PET value is up to 30.8 in winter（middle hot stress） ,while Ta is about 5~6℃，which is incompatible with common sense. and when Ta is about 25℃，the PET is over 41℃（Extreme heat stress）。

By comparing with other papers, the data in other parts of China are consistent with common sense.So I think the PET value is abnormal.

I'd like to know I wonder if anyone has the same problem ? and what's the matter ? Is the calculation model unapplicable to some areas/climate type? will the reason be the global radiation is too high to influence the result? will there be some calculation condition or operating steps that I didn't do well?

I'll give some data as a example to help find out the problem.
thank you for your patient reading and I would appreciate it if you could give me some advice!

the measurement data are as follows:
