UTLS THESEO: Balloon-borne Near-IR laser spectrometer atmospheric methane measurements from Kiruna station, Sweden

Extension of the Third European Stratospheric Experiment on Ozone (THESEO) balloon-borne measurements of atmospheric tracers and chemically active gases in the mid-latitude lower stratosphere for tests of atmospheric transport UTLS Round 1 project led by Dr R.L.Jones, Dr J.A.Pyle and Dr Neil Harris, Centre for Atmospheric Sciences, University of Cambridge and P.T. Woods, National Physical Laboratory (NPL).

This dataset contains atmospheric methane measurements from a balloon-borne near-IR laser spectrometer.

The data shows the methane mixing ratio at different atmospheric pressures. The overall scientific objective within this proposal was to contribute to the understanding of middle latitude ozone loss by making measurements of a number of important tracers of atmospheric motion and photochemistry, and by interpreting these measurements with state-of-the-art models of atmospheric chemistry and transport.

本数据集拓展了第三次欧洲平流层臭氧实验（THESEO）对中纬度平流层大气示踪剂和化学活性气体进行的气球搭载测量，旨在检验大气传输UTLS Round 1项目。该项目由剑桥大学大气科学中心R.L.Jones博士、J.A.Pyle博士和Neil Harris博士以及国家物理实验室（NPL）的P.T. Woods博士共同领导。该数据集包含从气球搭载近红外激光光谱仪获取的大气甲烷测量数据。数据展示了不同大气压力下的甲烷混合比。在本次提案的整体科学目标中，旨在通过测量众多大气运动和光化学的重要示踪剂，并利用最先进的化学和传输模型对这些测量结果进行解读，以增进对中纬度臭氧损耗机制的理解。
