资源简介:
SETCD (Satellite and ERA5-based Tropical Cyclone Dataset), a comprehensive dataset encompassing satellite imagery data and ERA5 data for all TCs recorded between 1980 and 2022. Our dataset is derived from two publicly available data sources: GridSat-B1 and ERA5. To capture relevant information associated with TC, SETCD adopts the latitude and longitude positions provided by IBTrACS as the center points. The satellite data within the SETCD dataset consists of three channels from GridSat-B1: infrared, water vapor, and visible. The ERA5 data in the SETCD dataset is selected based on the same criteria as Pangu-Weather, including 5 atmospheric variables (geopotential (z), specific humidity (q), zonal component of wind (u), meridional component of wind (v), and temperature (t)), each with 13 pressure levels (e.g., z50 denotes the geopotential height at a pressure level of 50 hPa), and 4 surface variables (10-meter u wind component (u10), 10-meter v wind component (v10), 2-meter temperature (t2m), and mean sea level pressure (msl)).
SETCD(基于卫星与ERA5的热带气旋数据集,Satellite and ERA5-based Tropical Cyclone Dataset)是一套涵盖1980年至2022年间所有已记录热带气旋(TC, Tropical Cyclone)的卫星影像数据与ERA5数据的综合数据集。本数据集源自两个公开可用的数据源:GridSat-B1与ERA5。为获取与热带气旋相关的有效信息,SETCD采用IBTrACS提供的经纬度坐标作为气旋中心点位。SETCD中的卫星数据取自GridSat-B1的三个通道:红外通道、水汽通道与可见光通道。SETCD中的ERA5数据采用与Pangu-Weather一致的筛选标准,包含5种大气变量:位势(z)、比湿(q)、纬向风分量(u)、经向风分量(v)与气温(t),每个变量对应13个气压层(例如z50表示50百帕气压层的位势高度),以及4种地表变量:10米纬向风分量(u10)、10米经向风分量(v10)、2米气温(t2m)与平均海平面气压(msl)。
