NJIAS Himawari-8/9 Cloud Feature Dataset (HCFD)–0.04Deg. Part IV: 2022–2023

The NJIAS HCFD–0.04Deg provides a comprehensive description of cloud features over the west North Pacific regions spanning 10°N–50°N and 80°E–170°W. It includes 26 variables, such as cloud mask, type, top height, optical thickness, and particle effective radius, as well as snow and dust masks, which were generated from the visible and infrared measurements of the Advanced Himawari Imager onboard the Japanese geostationary satellites Himawari-8/9, based on a series of cloud retrieval algorithms developed by Dr. Zhuge. As the fourth part of NJIAS HCFD–0.04Deg, this dataset covers the period from January 2022 to December 2023, with a temporal resolution of 30 min and a spatial resolution of 0.04°. The data are now distributed under CC BY 4.0 license.

NJIAS HCFD–0.04Deg数据集提供了西北太平洋区域（覆盖10°N–50°N、80°E–170°W）内云特征的完整描述。该数据集包含26项变量，涵盖云掩膜（cloud mask）、云类型、云顶高度、光学厚度、粒子有效半径以及雪掩膜与沙尘掩膜；其数据基于诸葛博士开发的一系列云反演算法，由搭载于日本静止轨道卫星“向日葵-8/9”（Himawari-8/9）的先进向日葵成像仪（Advanced Himawari Imager）所获取的可见光与红外探测数据反演生成。作为NJIAS HCFD–0.04Deg数据集的第四个子集，本数据集的时间跨度为2022年1月至2023年12月，时间分辨率为30分钟，空间分辨率为0.04°。当前本数据集采用CC BY 4.0许可协议进行发布。
