EAGER: Surface Skin Temperature Mapping by Ultralight Aircraft and Undergraduate Participation for Stable Atmospheric Variability ANd Transport (SAVANT)

稳定的大气变率和运输现场实验将于2018年秋季在伊利诺伊州中部进行。 该活动的目标是测量平缓地形中的极低空气流。 这种研究需要对现场进行高密度温度测量。 该合同将提供来自红外摄像机的表面温度的空中测量，这将有助于填补地面测量之间的空白。 该相机将安装在一架超轻型飞机上，这种飞机能够飞得非常低，非常慢，同时不会遇到与许多无人驾驶飞机相同的限制。 增加的仪器将提高该项目回答与农业和危险材料释放有关的微气象条件问题的能力。 该项目还将作为一个新的观测平台的初步示范，并为学生提供宝贵的实地研究机会。该奖项是为了在稳定大气变率和传输（称为SAVANT）实地活动期间收集表面皮肤温度的机载辐射观测。 SAVANT是NSF资助的一项实地研究，旨在调查浅沟中辐射驱动的冷空气排放流的动力学。 该活动有各种地面温度传感器，该奖项将通过使用FLIR Duo Pro R热成像相机提供表面皮肤温度的2D地图来增强这些测量。 该活动的新颖之处在于，相机将在载人超轻型飞机上飞行，这是一个在大气科学界没有重要用途的平台。 研究人员还将部署一架能够携带相机的无人机作为风险缓解策略。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Stable Atmospheric Variability and Transport field experiment will be conducted in the Fall of 2018 in central Illinois. The goal of the campaign is to measure very low-level air flow in gentle terrain. This kind of study requires high-density temperature measurements of the field site. This award will provide airborne measurements of surface temperature from an infrared camera that will help to fill in the gaps between the ground-based measurements. The camera will be mounted on an ultralight aircraft, which is able to fly very low and very slow, while not running into the same restrictions as many unmanned aircraft. The additional instruments will enhance the ability of the project to answer questions about micro-meteorological conditions that are relevant to agriculture and hazardous materials release. The project will also serve as an initial demonstration for a new observing platform and provide valuable field research opportunities for students.This award is for the collection of airborne radiometric observations of surface skin temperatures during the Stable Atmospheric Variability and Transport (known as SAVANT) field campaign. SAVANT is an NSF-funded field study investigating the dynamics of radiatively-driven cold air drainage flows in shallow gullies. The campaign has a variety of ground based sensors for temperature and this award will enhance those measurements by providing 2D maps of surface skin temperature using a FLIR Duo Pro R thermal camera. The novel aspect of the campaign is that the camera would be flown on a manned ultralight aircraft, which is a platform that does not have significant usage in the atmospheric science community. The researchers will also deploy a UAS that is capable of carrying the camera as a risk mitigation strategy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
