• Number of spikes
• These are spikes in the retrieved HNO3 mixing ratios for records with MMAF_STAT = G/T/t and DQI = 4/2 (that is, good records with good radiances). Spikes are identified by comparison of their deviation from the monthly zonal mean with the rms variability (sigma) calculated in distinct 6 degree latitude bins.
