Software and hardware validation for meteorological station

Software has become almost an essential part of any scientific system in recent years. This made many systems easier to use, more reliable and more flexible. However the increasing complexity of this software is itself a potential source of errors that can remain undetected. Users and developers of such systems need to be aware of the risks involved and take appropriate precautions. Validation and testing is a way of investigating and proving the integrity and fitness for purpose of the (software parts of the) measurement system. Also, software validation is considered as a critical tool used to assure the correct operation and functionality of the system. (author)
