Turbulent fluxes of carbon dioxide in the urban boundary layer

A dataset of 520-hrs time series of co2 turbulent fluxes in the urban boundary layer. The turbulent fluxes is calculated by using eddy-covariance method.<br>The data type is Matlab cell (1 raw and 520 columns). You can open Matlab and use the function 'load' to read data. Each column is 1-hr time series. The sampling frequency is 10Hz. The unit of data is 'mmol m^-2 sec^-1'.本数据集包含城市边界层内二氧化碳湍流通量的520小时时间序列数据。湍流通量采用涡动协方差（eddy-covariance）方法计算得到。<br>该数据集的存储格式为Matlab元胞数组（Matlab cell），维度为1行520列。用户可通过Matlab软件调用`load`函数读取该数据。每一列对应1小时的时间序列，采样频率为10赫兹（Hz），数据单位为`mmol·m⁻²·sec⁻¹`。
