- the methods described in a variant greatly improve the precision of the measurement of the total gross flux Qb, while maintaining a simple integration compared to Kriging methods.
- the gross total measurement Qb is more precise if the wind speed changes rapidly or if an obstacle present between the source 14 and a line 50 affects the wind speed on the line 50.
