Each file corresponds to the whole winter time data set of the station identified by its ID: O3_PassActSLIMCAT_CompositeMSR2SAOZ_ID.txt

1st column: Year

2nd column: Day of Year (DoY)

3rd column: Passive ozone column (without chemistry) modelled by TOMCAT/SLIMCAT (O3pasS).

4th column: Active ozone column (with full chemistry) modelled by TOMCAT/SLIMCAT (O3actS).

5th column: merged data from SAOZ observations and MSR2 (O3comp)

Passive and active tracers of SLIMCAT were normalized to O3comp data in the beginning of the winter.

NaN is used when there is no observation either from SAOZ instrument or MSR2 dataset or from the model.

每个文件对应以编号标识的科考站的完整冬季时段数据集，文件命名规则为：`O3_PassActSLIMCAT_CompositeMSR2SAOZ_ID.txt`。

文件各列含义如下：
1. 第1列：年份（Year）
2. 第2列：日序（Day of Year，简称DoY）
3. 第3列：由TOMCAT/SLIMCAT模拟的被动臭氧柱总量（无化学过程），记为`O3pasS`
4. 第4列：由TOMCAT/SLIMCAT模拟的主动臭氧柱总量（包含完整化学过程），记为`O3actS`
5. 第5列：SAOZ观测数据与MSR2数据融合后的臭氧柱总量，记为`O3comp`

SLIMCAT的被动与主动示踪剂在冬季初始时刻已针对`O3comp`数据集进行归一化处理。

当SAOZ仪器、MSR2数据集或模式模拟结果均无有效观测时，使用`NaN`（非数值）标记缺失数据。
