浅层积云对流的大涡模拟(LES)结果直接与小型积云微物理研究(SCMS)中的云内飞机测量结果相比较。为此，首先根据可获得的观测(在SCMS期间)构建LES案例。然后利用条件采样场将模拟结果与云内测量结果直接进行比较。SCMS数据集的一个优势是结合了一系列不同的表面测量、飞机在云层中多个级别的云内测量以及高分辨率陆地卫星图像的可用性。
Large‐eddy simulation (LES) results of shallow cumulus convection are directly evaluated against in‐cloud aircraft measurements, as made during the Small Cumulus Microphysics Study (SCMS). To this purpose an LES case is first constructed, based on available observations (during SCMS). Then the simulations are directly compared with the in‐cloud measurements by using conditionally sampled fields. An advantage of the SCMS dataset is the combination of a range of different surface measurements, in‐cloud measurements by an aircraft at many levels in the cloud layer, and the availability of high‐resolution Landsat images.
