I am interested in the random error calculation in EddyPro 4 as I can not find any information about how it is derived in the manual. Can you give me more detail?
This is the first time I have seen any attempt at uncertainty estimation in flux calculation and interested in how people see it being used in there quality assurance process. Surely the inference being if your random error is high say at least 3x your measured flux then you can have little confidence in it and so should remove it from further calculations and use gap filling techniques too fill the gap?
The eddypro help system has a detailed section on how the random error is estimated.
There are two different methods available and both are based on the determination of Integral Turbulent time Scale (ITS). Please check this link below to see this section and let us know if you need more information
