Co-ordinated Airborne Studies in the Tropics (CAST): In-situ airborne, ozonesonde and ground based and atmospheric chemistry measurements

The CAST dataset contains data produced by the the NERC Co-ordinated Airborne Studies in the Tropics (CAST) project. CAST was a collaborative initiative with NASA's Airborne Tropical Tropopause Experiment (ATTREX) programme to study the Tropical Tropopause Layer (TTL) over the Pacific Ocean and South East Asia.

This data collection includes airborne measurements made by the FAAM (Facility for Airborne Atmospheric Measurements) BAe-146 aircraft whilst deployed in Guam in Jan/Feb 2014 during coordinated flights with NASA's Global Hawk making corresponding in situ measurements in the TTL over the West Pacific. In addition to these in situ aircraft measurements, the dataset comprises balloon-based measurements of ozone and ground-based ozone, CO2, CH4, CO and very short-lived halogen species. A complementary group of regional high resolution models, global composition models and a global cirrus model will also be used to address fundamental questions related to atmospheric composition, radiation and transport.

CAST数据集囊括了由NERC协同空中研究计划（CAST）项目产生的数据。CAST项目是一项与NASA的空中热带对流层实验（ATTREX）计划合作发起的倡议，旨在研究太平洋及东南亚地区的热带对流层层（TTL）。本数据集包含了FAAM（空中大气测量设施）BAe-146飞机在2014年1月/2月在关岛部署期间，与NASA的全球鹰无人机进行协调飞行时所进行的空中测量数据。除了这些原位飞机测量数据外，还包括了基于气球的臭氧、地面臭氧、二氧化碳、甲烷、一氧化碳以及非常短寿命的卤素物种的测量数据。此外，还将使用一组区域高分辨率模型、全球组成模型以及全球卷云模型，以解决与大气组成、辐射和传输相关的根本性问题。
