抽象的。五台便携式Bruker EM 27/SUN FTIR（傅里叶变换红外）光谱仪已被用于准确和精确地观测主要城市柏林周围CO2和CH 4的柱平均丰度。在Frey等人（2015）的工作中，开发了一种校准程序，并将其应用于柏林活动所用的光谱仪。在这里，我们描述的观测设置的活动和数据分析方面，我们提出了记录的时间序列的XCH 4和XCO 2。我们证明，柏林的CO2排放量可以清楚地确定在观测。应用一个简单的弥散模型，表明柏林源的总强度约为0.8 t CO2 s-1。在本工作的补充中，我们提供了测量数据集和辅助数据。我们希望，该模型社区将利用这一独特的数据集的国家的最先进的反演研究的CO2和CH 4来源在柏林地区。
Abstract. Five portable Bruker EM27/SUN FTIR (Fourier transform infrared) spectrometers have been used for the accurate and precise observation of column-averaged abundances of CO2 and CH4 around the major city Berlin. In the work by Frey et al. (2015), a calibration procedure is developed and applied to the set of spectrometers used for the Berlin campaign. Here, we describe the observational setup of the campaign and aspects of the data analysis, and we present the recorded time series of XCH4 and XCO2. We demonstrate that the CO2 emissions of Berlin can be clearly identified in the observations. A simple dispersion model is applied which indicates a total strength of the Berlin source of about 0.8 t CO2 s−1. In the Supplement of this work, we provide the measured data set and auxiliary data. We hope that the model community will exploit this unique data set for state-of-the art inversion studies of CO2 and CH4 sources in the Berlin area.
