INCOMPASS实地活动结合了2016年印度季风的空中和地面测量，最终目标是更好地预测季风降雨。季风提供了南亚的大部分水，但从几天到季节的预测受到模型参数化中快速发展的大误差的限制。由于缺乏详细的观测，无法彻底了解季风环流及其与陆地表面的相互作用：这是一个由边界层和对流云动力学控制的过程。INCOMPASS使用英国机载大气测量设施（FAAM）BAe-146飞机在印度进行了第一个这种规模的项目，在2016年6月和7月进行了近100小时的观测。从勒克瑙飞往北方平原的航班对西部干燥的沙漠空气和孟加拉湾北方的潮湿环境之间的表面和边界层结构进行了采样。这些飞行在季风前和季风条件下重复。从位于印度南部的孟加拉国的第二个基地起飞的航班测量了从阿拉伯海到西高止山脉，再到印度东南部和孟加拉湾南部的雨影的大气对比。飞行计划得到了英国气象局和印度NCMRWF定制的4公里对流允许有限区域模型的预测的帮助。在地面上，INCOMPASS在一系列地表类型上安装了涡度相关通量塔，以提供地表通量及其昼夜和季节周期调制的详细测量。这些数据将用于更好地量化大气对陆地表面的影响，反之亦然。INCOMPASS还在坎普尔和布巴内斯瓦尔安装了地面仪器超级站。在这里，我们激励和描述INCOMPASS现场活动。我们使用两个飞行的例子来说明大气结构的对比，特别是在季风爆发期间撤退的中层干侵入。

The INCOMPASS field campaign combines airborne and ground measurements of the 2016 Indian monsoon, towards the ultimate goal of better predicting monsoon rainfall. The monsoon supplies the majority of water in South Asia, but forecasting from days to the season ahead is limited by large, rapidly developing errors in model parametrizations. The lack of detailed observations prevents thorough understanding of the monsoon circulation and its interaction with the land surface: a process governed by boundary‐layer and convective‐cloud dynamics. INCOMPASS used the UK Facility for Airborne Atmospheric Measurements (FAAM) BAe‐146 aircraft for the first project of this scale in India, to accrue almost 100 h of observations in June and July 2016. Flights from Lucknow in the northern plains sampled the dramatic contrast in surface and boundary‐layer structures between dry desert air in the west and the humid environment over the northern Bay of Bengal. These flights were repeated in pre‐monsoon and monsoon conditions. Flights from a second base at Bengaluru in southern India measured atmospheric contrasts from the Arabian Sea, over the Western Ghats mountains, to the rain shadow of southeast India and the south Bay of Bengal. Flight planning was aided by forecasts from bespoke 4 km convection‐permitting limited‐area models at the Met Office and India's NCMRWF. On the ground, INCOMPASS installed eddy‐covariance flux towers on a range of surface types, to provide detailed measurements of surface fluxes and their modulation by diurnal and seasonal cycles. These data will be used to better quantify the impacts of the atmosphere on the land surface, and vice versa. INCOMPASS also installed ground instrumentation supersites at Kanpur and Bhubaneswar. Here we motivate and describe the INCOMPASS field campaign. We use examples from two flights to illustrate contrasts in atmospheric structure, in particular the retreating mid‐level dry intrusion during the monsoon onset.
