Filtering LI-7700 high frequency data using diagnostic value information
The LI-7700 outputs a variable titled DIAG – Diagnostic Value, at the same output rate as the measured data stream which can be used to filter the raw high frequency data. The diagnostic value from the LI-7700 is a 16-bit number that can be broken down to the 16 individual bits to identify various diagnostic information about the instrument. When processing LI-7700 data for Eddy covariance measurements, the raw data needs to be filtered to exclude situations when the measured…
