Atmospheric CO2 Concentrations from Aircraft for 1972-1981, CSIRO Monitoring Program

From 1972 through 1981, air samples were collected in glass flasks from aircraft at a variety of latitudes and altitudes over Australia, New Zealand, and Antarctica. The samples were analyzed for CO2 concentrations with nondispersive infrared gas analysis. The resulting data contain the sampling dates, type of aircraft, flight number, flask identification number, sampling time, geographic sector, distance in kilometers from the listed distance measuring equipment (DME) station, station number of the radio navigation distance measuring equipment, altitude of the aircraft above mean sea level, sample analysis date, flask pressure, tertiary standards used for the analysis, analyzer used, and CO2 concentration. These data represent the first published record of CO2 concentrations in the Southern Hemisphere expressed in the WMO 1981 CO2 Calibration Scale and provide a precise record of atmospheric CO2 concentrations in the troposphere and lower stratosphere over Australia and New Zealand.

1972年至1981年间，科研人员于澳大利亚、新西兰及南极洲上空的不同纬度与海拔高度的航空器平台上，采用玻璃烧瓶采集大气样本。随后采用非色散红外气体分析法（nondispersive infrared gas analysis）对样本的二氧化碳（CO₂）浓度开展检测分析。
所得数据集涵盖以下字段：采样日期、航空器型号、航班编号、烧瓶标识编号、采样时刻、地理分区、与指定测距设备（Distance Measuring Equipment, DME）站点的千米级距离、无线电导航测距设备站点编号、航空器相对于平均海平面的飞行高度、样本分析日期、烧瓶内气压、分析所用的三级标准物质、所用分析仪型号以及二氧化碳浓度。
本数据集为南半球首个采用世界气象组织（World Meteorological Organization, WMO）1981年二氧化碳校准标尺标定的大气二氧化碳浓度公开记录，精准呈现了澳大利亚与新西兰上空对流层（troposphere）及平流层下层（lower stratosphere）的大气二氧化碳浓度分布情况。
