LIS 0.1 DEGREE VERY HIGH RESOLUTION GRIDDED LIGHTNING ANNUAL CLIMATOLOGY (VHRAC) V1

The LIS 0.1 Degree Very High Resolution Gridded Lightning Annual Climatology (VHRAC) dataset consists of gridded annual 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度超高分辨率网格化闪电年度气候学（VHRAC）数据集，由闪电成像传感器（LIS）自1998年1月1日至2013年12月31日观测到的总闪电闪击率网格化年度气候学数据组成。LIS是搭载于热带降雨测量任务（TRMM）卫星上的仪器，用于探测地球热带和亚热带地区总闪电的分布与变化。这些信息可用于严重风暴的检测与分析，以及闪电与大气相互作用的研究。网格化气候学包括年度平均闪击率、24小时分辨率的平均日周期闪击率和以日、月或季节分辨率的平均年度周期闪击率。所有数据集均以0.1度空间分辨率呈现。闪击率年度周期数据集（即，日、月或季节）均包含49天和1度箱形移动平均，旨在消除日周期并平滑低闪击率区域，从而使结果更加稳健。
