SARin Discriminator Parameters Monitoring

Source: L2i (LRM, SAR, SARin) · Variables: sarin_output_1_20_ku, sarin_output_2_20_ku, sarin_output_3_20_ku, sarin_output_4_20_ku, sarin_output_5_20_ku, sarin_output_6_20_ku, sarin_output_7_20_ku, sarin_output_8_20_ku, sarin_output_9_20_ku, sarin_output_10_20_ku

Waveform parameters computed by the SARin surface type discriminator (sarin_output_1-10). Only used in SARin mode. Zero values (not computed, ~2% of SARin records, and sea ice peakiness outside sea ice areas) are excluded. Bin values are in waveform range bins.

Area
All areas Global North Polar (>60N) South Polar (<60S)

Only SARin mode measurements are used. Product values of 0 (not computed or not applied) are excluded.

Statistics use every 20 Hz measurement of the cycle within each area. Std Dev is the population standard deviation, RMS the root mean square.
