NJIAS Himawari-8/9 Typhoon Cloud Feature Dataset (HTCFD). Part II: 2022–2024
收藏资源简介:
The NJIAS HTCFD provides a comprehensive description of radiance and cloud features within a 20° × 20° longitude-latitude grid box surrounding the center of west North Pacific typhoons. It includes 36 variables, with 10 being the visible and infrared measurements from the Advanced Himawari Imager onboard the Japanese geostationary satellites Himawari-8/9 (i.e., visible and near-infrared albedo and infrared brightness temperatures). The remaining 26 variables are cloud parameters such as cloud/overshooting-top mask, cloud type, cloud top height, cloud optical thickness, cloud particle effective radius, and cloud motion vectors, generated using a series of cloud retrieval algorithms developed by Dr. Zhuge. As the second part of NJIAS HTCFD, this dataset covers the three-year period from 2022 to 2024, with a temporal resolution of 30 min and a spatial resolution of 0.02°.
NJIAS HTCFD数据集全面描述了西北太平洋台风中心周边20°×20°经纬度网格单元内的辐射与云系特征。该数据集共包含36个变量,其中10个为日本静止气象卫星Himawari-8/9搭载的先进葵花成像仪(Advanced Himawari Imager)所获取的可见光与红外测量数据,具体包括可见光、近红外反照率及红外亮温。剩余26个变量为云参数,涵盖云/过冲云顶掩膜、云类型、云顶高度、云光学厚度、云粒子有效半径以及云运动矢量等,均由诸葛博士开发的一系列云反演算法生成。作为NJIAS HTCFD的第二部分,该数据集的时间跨度为2022年至2024年,共计三年,时间分辨率为30分钟,空间分辨率为0.02°。
