LIS/OTD 0.5 Degree High Resolution Annual Climatology (HRAC) V2.3.2015

The LIS/OTD 0.5 Degree High Resolution Annual Climatology (HRAC) 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 HRAC dataset includes annual flash rate climatology data on a 0.5 degree grid in HDF and netCDF-4 format.

LIS/OTD 0.5度高分辨率年度气候学数据集（HRAC）汇集了来自两种闪电探测传感器的总闪电闪光率格网气候数据，包括搭载于Orbview-1卫星的光学瞬态探测器（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，LIS的长期记录（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区域尤为稳健，而高纬度数据则完全由OTD提供。HRAC数据集包含以0.5度网格形式存储的年度闪光率气候学数据，并以HDF和netCDF-4格式呈现。
