LIS/OTD 2.5 Degree Low Resolution Annual Climatology Time Series (LRACTS) V2.3.2015

The LIS/OTD 2.5 Degree Low Resolution Annual Climatology Time Series (LRACTS) consists of gridded climatologies of total lightning flash rates seen by the spaceborne Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS). The long LIS (equatorward of about 38 degree) record makes the merged climatology most robust in the tropics and subtropics, while the high latitude data is entirely from OTD. The LRACTS dataset include annual flash rate time series data in MP4 format.

LIS/OTD 2.5 度低分辨率年气候时间序列（LRACTS）由搭载于航天器的光学瞬态探测器（OTD）和闪电成像传感器（LIS）观测到的总闪电闪光率的格网气候学数据组成。长周期 LIS 记录（约38度赤道以南）使得合并的气候学数据在热带和副热带区域尤为稳健，而高纬度数据则完全来自 OTD。LRACTS 数据集包含以 MP4 格式存储的年闪电闪光率时间序列数据。
