L2I Beam Behaviour Parameters Monitoring

Cryosat L2I data includes a set of Beam Behaviour parameters (L2I field 33) for each 20Hz measurement record to characterise the shape of the set of Doppler echoes from a common surface location prior to stacking. Currently the first five parameters are defined, while the remainder are reserved for future use.

This tool provides global and polar plots of the first five Beam Behaviour parameters for each 30-day data take.

Index	Parameter	Units
0	Standard Deviation	Unitless
1	Stack Centre	Unitless:Stack Beam/100
2	Stack Scaled Amplitude	Normalised value 65535
3	Stack Skewness	Unitless: Value/100 or -99900 if cannot be computed
4	Stack Kurtosis	Microradians: Value/100 or -99900 if cannot be computed
