LIS/OTD 0.5 Degree High Resolution Monthly Climatology (HRMC) V2.3.2015

The LIS/OTD 0.5 Degree High Resolution Monthly Climatology (HRMC) 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 HRMC dataset include monthly flash rate climatology and flash rate seasonal climatology data on a 0.5 degree grid in HDF and netCDF-4 format.

LIS/OTD 0.5 度高分辨率月度气候学（HRMC）数据集汇聚了多种格网化的总闪电闪现频率气候学，这些数据由两种闪电探测传感器获取——分别是搭载于 Orbview-1 的空间光学瞬变探测器（OTD）以及位于热带降水测量任务（TRMM）卫星上的闪电成像传感器（LIS）。由于 LIS 的长期记录（约在38度赤道向内），使得合并后的气候学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。HRMC 数据集包括每月闪电闪现频率气候学以及季节性气候学数据，这些数据均以 0.5 度的网格形式存储于 HDF 和 netCDF-4 格式中。
