Real-Time vs. Post-Processed Impulse CMCs

Here is a scatterplot of real-time vs. post-processed impulse CMC (iCMC) values for 9 May and 20 June 2007. There is some decorrelation between the two, and a negative bias in the real-time values. However, the relationship is robust enough that we may be able to use bias-corrected, real-time data quantitatively with modest error.

As a bonus, here are real-time iCMC and post-processed continuing current CMC vs. total CMC for available 9 May and 20 June flashes. Real-time iCMC bears little relationship to total CMC, which is mainly driven by continuing current.
