收藏资源简介:
MetOp ERA5 PABLH数据集是一个大规模数据集,包含MetOp卫星辐射数据与ERA5行星大气边界层高度(PABLH)目标数据的匹配。数据集覆盖2022年全年,每周采样一次(从1月3日到12月26日),每个日期有四个同步过境时间(00、06、12和18 UTC),包含194个MetOp-C卫星轨道通道,总计超过430万个样本,分布在不同季节和纬度。此外,数据集还包括来自2025年两个日期的30个额外过境数据,与TEAMx观测活动匹配,用作独立的分布外评估集。数据以HDF5文件格式存储,每个文件对应一个轨道通道,包含地理定位信息(如经纬度、卫星和太阳天顶角、表面高度和类型)、数据(如IASI红外辐射、AMSU-A和MHS亮温、云标志以及PABLH目标变量)和AVHRR云统计信息。目标变量是ERA5 PABLH的平均值,用于回归分析,基于批量理查森数方法计算。数据集旨在支持从协同微波和红外观测中检索行星大气边界层高度的研究。
The MetOp ERA5 PABLH Dataset is a large-scale dataset of MetOp satellite radiances collocated with ERA5 Planetary Atmospheric Boundary Layer Height (PABLH) targets. It covers the calendar year 2022, sampled weekly (from 3 January to 26 December), with four synoptic overpass times per date (00, 06, 12, and 18 UTC), containing 194 orbital passages from the MetOp-C satellite, totaling over 4.3 million samples distributed across all seasons and latitudes. Additionally, the dataset includes 30 extra overpasses from two dates in 2025, collocated with the TEAMx observational campaign, used as an independent out-of-distribution evaluation set. Data is stored in HDF5 files, each corresponding to one orbital passage, containing geolocation information (e.g., latitude, longitude, satellite and solar zenith angles, surface height and type), data (e.g., IASI infrared radiances, AMSU-A and MHS brightness temperatures, cloud flags, and PABLH targets), and AVHRR cloud statistics. The target variable is the mean ERA5 PABLH, used for regression analysis and derived using the bulk Richardson number method. The dataset is designed to support research on retrieving planetary atmospheric boundary layer height from synergistic microwave and infrared observations.
