LIS 0.1 DEGREE VERY HIGH RESOLUTION GRIDDED LIGHTNING MONTHLY CLIMATOLOGY (VHRMC) V1

The LIS 0.1 Degree Very High Resolution Gridded Lightning Monthly Climatology (VHRMC) dataset consists of gridded monthly climatologies of total lightning flash rates seen by the Lightning Imaging Sensor (LIS) from January 1, 1998 through December 31, 2013. LIS is an instrument on the Tropical Rainfall Measurement Mission satellite (TRMM) used to detect the distribution and variability of total lightning occurring in the Earth's tropical and subtropical regions. This information can be used for severe storm detection and analysis, and also for lightning-atmosphere interaction studies. The gridded climatologies include annual mean flash rate, mean diurnal cycle of flash rate with 24 hour resolution, and mean annual cycle of flash rate with daily, monthly, or seasonal resolution. All datasets are in 0.1 degree spatial resolution. The mean annual cycle of flash rate datasets (i.e., daily, monthly or seasonal) have both 49-day and 1 degree boxcar moving averages to remove diurnal cycle and smooth regions with low flash rate, making the results more robust.

LIS 0.1 度超高清网格化月度闪电气候学数据集（VHRMC）由闪电成像传感器（LIS）自1998年1月1日至2013年12月31日所观测到的月度总闪电闪光率网格化气候学组成。LIS 是搭载于热带降雨测量任务卫星（TRMM）上的仪器，用于检测地球热带和亚热带地区的总闪电分布及其变异性。此类信息可用于恶劣天气的探测与分析，亦适用于闪电与大气相互作用的研究。网格化气候学数据包括年际平均闪光率、平均日际闪光率循环（24小时分辨率）以及平均年际闪光率循环（日、月或季节分辨率）。所有数据集均采用0.1度空间分辨率。年际平均闪光率数据集（即日、月或季节）均包含49天和1度箱型移动平均，以消除日际循环并平滑低闪光率区域，从而使得结果更为稳健。
