LIS 0.1 DEGREE VERY HIGH RESOLUTION GRIDDED LIGHTNING DIURNAL CLIMATOLOGY (VHRDC) V1

The LIS 0.1 Degree Very High Resolution Gridded Lightning Diurnal Climatology (VHRDC) dataset consists of gridded diurnal 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度超高清闪电日气候网格化数据集（VHRDC）包含了从1998年1月1日至2013年12月31日，由闪电成像传感器（LIS）观测到的全球闪电总闪频的日气候网格化数据。LIS是热带降雨测量任务（TRMM）卫星上的一个仪器，用于检测地球上热带和亚热带地区闪电的分布和变化。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。网格化气候数据包括年平均闪频、24小时分辨率的平均日周期闪频以及以每日、每月或季节分辨率的年平均周期闪频。所有数据集的空间分辨率为0.1度。年平均周期闪频数据集（即每日、每月或季节）均包含49天和1度箱型移动平均，以消除日周期并平滑低闪频区域，从而使得结果更加稳健。
