本文件夹包含与论文《凝迹云与否：气候最优航线的“可行性”探讨》相关的数据集。所有脚本与代码均单独维护于：https://github.com/junzis/contrail-or-not。如需了解更多细节，请查阅论文：https://arxiv.org/abs/2504.13907

概述
本数据集支持论文中关于优化飞行轨迹以减少凝迹云形成的相关分析。所提供的数据包括：
1. 气象代价网格（Meteorological cost grids）：ARPEGE与ERA5模式数据
2. 飞行轨迹数据（原始与已处理版本）
3. 航空器数据库
4. 中间数据与汇总统计量

数据目录结构如下：
`arpege/`：ARPEGE模式气象数据
`cache/`：用于占用率计算的中间或缓存数据
`eu_flights_2022feb20_raw.parquet.gz`：当日原始飞行数据
`eu_flights_2022feb20_filter_resample_meteo.parquet.gz`：对原始飞行数据进行过滤、重采样后，并与气象数据聚合得到的已处理飞行数据集
`grid_arpege_smoothed.parquet.gz`：平滑后的ARPEGE气象网格数据
`grid_era5_smoothed.parquet.gz`：平滑后的ERA5气象网格数据
`aircraft_db.csv`：包含ICAO地址（ICAO address）、航空器类型代码、注册号与运营方信息的航空器数据库
`europe_acc.txt`：欧洲空域/机场信息
`stats_results.csv`：汇总统计量与实验结果
