LIS/OTD 2.5 Degree Low Resolution Diurnal Climatology (LRDC) V2.3.2015

The LIS/OTD 2.5 Degree Low Resolution Diurnal Climatology (LRDC) contains a variety of gridded climatologies of total lightning flash rates obtained from two lightning detection sensors - the spaceborne Optical Transient Detector (OTD) on Orbview-1 and the Lightning Imaging Sensor (LIS) onboard the Tropical Rainfall Measuring Mission (TRMM) satellite. 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 LRDC dataset include diurnal flash rate climatology data including raw and scaled flashes on a 2.5 degree grid in HDF and netCDF-4 format.

LIS/OTD 2.5度低分辨率日际气候学数据集（LRDC）收录了由两种闪电探测传感器获取的各类网格化总闪电闪光率气候学数据，这两种传感器分别为搭载于Orbview-1卫星的太空光学瞬变探测器（OTD）和搭载于热带降雨测量任务（TRMM）卫星上的闪电成像传感器（LIS）。其中，长周期的LIS数据（约38度赤道以南）使得合并后的气候学数据在热带和副热带地区具有极高的稳健性，而高纬度数据则完全来自OTD。LRDC数据集包含日际闪光率气候学数据，包括原始和缩放后的闪光数据，以2.5度网格形式存储于HDF和netCDF-4格式中。
