风云四号闪电成像仪聚类算法的参数化方案

open access: yesDianci bileiqi, 2019
风云四号静止卫星(FY-4)上携带的闪电成像仪(LMI,lightning mapping imager)可以很好地实时监测对流层的闪电活动情况,但由于目前公开的1 min事件产品(event)并不对应于一次次的闪电(flash),因此需要进行"聚类",也就是将事件产品(event)转化为闪电(flash)数据。为了得到适合LMI的闪电聚类算法,本文选取了LMI空间像元分辨率不同的两个典型区域,一个是像元分辨率约为8 km的西南地区(东经,北纬),另一个是像元分辨率约为12 km的东北地区(东经,北纬),

On-Orbit Response Characteristics of Fengyun-4A Lightning Mapping Imager (LMI) and Their Impacts on LMI Detection

Journal of Atmospheric and Oceanic Technology, 2023
Abstract The effects of the response characteristics of the Fengyun-4A Lightning Mapping Imager (LMI) on its detection capability were studied using the raw event data of LMI in 2020. The simultaneous observation data of the Lightning Imaging Sensor (LIS) on the International Space Station (ISS) were used to evaluate the LMI detection capability.
