About this file
This document contains questions and answers related to a request for proposals for a GeoXO Lightning Mapper Phase A study. The study is intended to define a GeoXO Lightning Mapper instrument that will provide lightning data to NOAA and other agencies to support weather forecasting and warnings. The questions and answers clarify that the instrument is expected to detect 95% of lightning events with an energy density above 3.8 uJ/m^2/sr, and that proposals must calculate the expected number of noise events that could be incorrectly identified as lightning events at the 5% or less false detection rate required for the L1b data product. The instrument is planned for the first NOAA GeoXO satellite launching in 2032.

GeoXO Lightning Mapper Phase A Study RFP Questions and Answers #1
Question 1- On LMXPORD120 Table 1, are the minimum energy density based on measured lightning events and that the cumulative percent column shows the percent of lightning detected to have greater than the minimum detectable event energy density? In other words, 95 percent of the lightning will have energy density greater than or equal to 3.8 uJ/m^2/sr within the oxygen triplet state spectrum?
Answer to Question 1- The vendor has made a correct reading of the table values. The first row indicates that 95% of detected lightning events have a lightning event energy greater than or equal to 3.8 µJ/m2/sr.
Question 2- How shall the false event probability be calculated, referenced on RFP LMXPORD121? Is this 5% at L1b in relation to all false events or all true events?
Answer to Question 2- The LMX system will produce the L1b data product of lightning events.
As far as the system is concerned, all L1b events are lightning events. The vendor must calculate the expected distribution of noise events from all noise sources and determine the expected number of noise events that will pass through the LMX system as lightning events. In terms of equations:
a. Total number of L1b events, N_L1b = N_true + N_false
b. N_false = number of false events calculated from all sources (read noise, shot noise, radiation, S/C jitter, etc.)
c. Prob_false = N_false/N_L1b, where Prob_false ≤ 5%
