Methane Observations and Yearly Assessments (MOYA): lower troposphere greenhouse gas data taken over Pantanal, Mato Grosso do Sul, Brazil

This dataset contains CH4, CO2, CO, N2O and SF6 dry air molar fraction vertical profiles over the Pantanal, Mato Grosso do Sul, Brazil with air sampled using small aircraft and analysed at Laboratório de Gases de Efeito Estufa (LAGEE), Sao Jose dos Campos, Brazil. The air was sampled during ascent of small airplane from 4.4 km above surface down to close to the ground. A series of flasks (17 flasks) were filled sequentially. The flasks were contained in a suitcase. Valves of the flasks were opened and closed by a programmable microcontroller. After sampling the suitcase were sent by mail to the high precision gas analytics laboratory LAGEE at Instituto Nacional de Pesquisas Espaciais (INPE), Sao Jose dos Campos, Brazil where the dry air molar fractions of the air of each flask were measured. These data were collected as part of the Methane Observations and Yearly Assessments (MOYA) project funded by the Natural Environment Research Council (NERC) (NE/N016211/1).

本数据集包含巴西南马托格罗索州潘塔纳尔湿地上空的甲烷（CH4）、二氧化碳（CO2）、一氧化碳（CO）、一氧化二氮（N2O）及六氟化硫（SF6）干空气摩尔分数垂直廓线数据，空气样本由小型航空器采集，并于巴西圣何塞杜斯坎普斯的温室气体实验室（Laboratório de Gases de Efeito Estufa, LAGEE）完成分析。空气样本采集于小型航空器从地表上方4.4千米高度下降至接近地面的过程中，共依次完成17个采样瓶的充气作业。所有采样瓶被收纳于一个手提箱内，其阀门由可编程微控制器控制启闭。采样完成后，该手提箱通过邮寄方式被送往巴西圣何塞杜斯坎普斯国家空间研究所（Instituto Nacional de Pesquisas Espaciais, INPE）下属的高精度气体分析实验室LAGEE，在此完成对每个采样瓶内空气的干空气摩尔分数测定。本数据集为英国自然环境研究委员会（Natural Environment Research Council, NERC）资助的甲烷观测与年度评估（Methane Observations and Yearly Assessments, MOYA）项目（资助编号NE/N016211/1）所采集的数据之一。
