LIS/OTD 2.5 Degree Low Resolution Annual Diurnal Climatology (LRADC) V2.3.2015
收藏资源简介:
The LIS/OTD 2.5 Degree Low Resolution Annual Dirunal Climatology (LRADC) 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 LRADC dataset include flash rate climatology data including scaled flash counts on a 2.5 degree grid in HDF and netCDF-4 format.
LIS/OTD 2.5度低分辨率年度日际气候学数据集(LRADC)收录了从两个闪电检测传感器——搭载于Orbview-1卫星的空间光学瞬变探测器(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)——获取的各类网格化总闪电闪烁率气候学数据。长周期LIS记录(约38度赤道以内的区域)使得合并后的气候学数据在热带和亚热带地区具有极高的稳健性,而高纬度数据则完全来自OTD。LRADC数据集包括在2.5度网格上的闪烁率气候学数据,包括按比例缩放的闪烁次数,并以HDF和netCDF-4格式存储。
