T-REX: ARL WRF ARW 2km Imagery. Version 1.0

This dataset contains images developed from the U.S. Army Research Laboratory (ARL) Advanced Research Weather Research and Forecasting (WRF ARW) modeling system. The 2km imagery were developed at the 12 UTC time and are available from 27 February 2006 to 30 April 2006. The ARL is currently studying the WRF-ARW to see how well it simulates complex mountain and boundary layer meteorology at horizontal grid spacings down to 1-2 km. The 2006 Terrain-induced Rotor Experiment (T-REX) across the Owens Valley of California has provided an opportunity for ARL to run the WRF-ARW in both near real-time and research modes, and at fine-scale horizontal grid spacings.

本数据集包含基于美国陆军研究实验室（U.S. Army Research Laboratory, ARL）先进研究型天气研究与预报（WRF ARW）模型系统生成的图像。该数据集的图像分辨率为2千米，成像时刻为协调世界时12时，时间跨度为2006年2月27日至2006年4月30日。目前，ARL正对WRF-ARW模型展开研究，以评估其在水平网格间距低至1-2千米的情况下，对复杂山地与边界层气象过程的模拟能力。2006年在加利福尼亚州欧文斯谷开展的地形诱发涡旋试验（T-REX），为ARL以准实时与科研运行模式、采用精细水平网格间距运行WRF-ARW模型提供了契机。
