WRF-STILT模型输入的气象站数据
CARVE: L4 Gridded Particle Trajectories for WRF-STILT model, 2012-2016
简介
该数据集为位于北极碳库脆弱性实验 (CARVE) 飞行路径(2012 - 2015 年)沿线位置的粒子接收器以及阿拉斯加和加拿大北极地区的各个气象站提供天气研究与预报 (WRF) 随机时间倒置拉格朗日传输 (STILT) 模型输入。每个产品包含多个 NetCDF 文件,打包为一个 TAR/GZIP 文件。这些数据对应于同样由 CARVE 科学团队生成的 WRF-STILT 模型足迹数据。
该数据集包含 72 个 TAR/GZIP 文件,其中包含 NetCDF 格式的 WRF-STILT 粒子文件。
