FACE-2 Data Reductions and Analyses (Prior to Disclosure of the Treatment Decisions): Part VI. Cloud-To-Ground Lightning Data for FACE-2

摘要

Lightning location data were obtained on 30 GO days (26 were B and 4 were A days) of the 61 GO days during FACE-2 for use in an exploratory analysis to determine if the treatment during FACE-2 resulted in any changes in the number and rate of cloud-to-ground lightning within the total and floating targets. It is estimated that 80% of the ground flashes within the target area were detected and located within 2-8 km. The total and floating target lightning data were reduced prior to disclosure of the treatment decision, minimizing the possibility of reduction bias.
