| 摘 要： | 利用风云三号B星(FY-3B)微波成像仪(Microwave Radiation Imager,MWRI)一级亮温数据和每6 h一次的热带气旋(tropical cyclone, TC)最佳路径数据进行时空匹配,建立了TC微波亮温数据集。该数据集包含了2011—2016年全球六大海盆生成的热带风暴级别以上的TC共计538个,以及对应每个TC的微波十通道亮温和36.50 GHz、89.00 GHz的极化校正亮温度,并简要阐明了该数据集在热带气旋研究方面的潜在应用,尤其对TC生命周期内的微波亮温特征及TC强度变化研究提供了有力的数据支撑。

| Abstract: | A tropical cyclone (TC) microwave brightness temperature database is established by using the spatio-temporal matching of the Fengyun-3B (FY-3B) Microwave Radiation Imager (MWRI) level-1 brightness temperature data and the TC best track data with an interval of 6 h. The database contains a total of 538 TCs above the tropical storm intensity level generated in 6 TC-prone basins from 2011 to 2016, as well as the 10-channel microwave brightness temperature and 36.50 GHz and 89.00 GHz polarization corrected temperature (PCT) corresponding to each TC. The potential application of this database in tropical cyclone research is also briefly clarified, and especially it provides strong data support for studying the microwave brightness temperature characteristics and TC intensity changes during the TC life cycle. |
