Lakes located in the Polish and Slovak parts of the Tatra Mountains were included in the Tatra diatom database (POL_SLOV training set). The relationship between the diatoms and the water chemistry in the surface sediments of 33 lakes was the basis for the statistical and numerical techniques for quantitative pH reconstruction. The reconstruction of the past water pH was performed using the alpine (AL:PE) and POL_SLOV training sets to compare the reliability of the databases for the Tatra lakes. The results showed that the POL_SLOV training set had better statistical parameters (R² higher by 0.16, RMSE and max. bias lower by 0.2 and 0.36, respectively) compared to the AL:PE training set. The better performance of the POL_SLOV training set is particularly visible in the case of Przedni Staw Polski where the curve of the inferred water pH shows an opposite trend for the period from the 1960s to 1990 compared to that based on the AL:PE dataset. The reliability of the inferred pH was confirmed by the comparison with current instrumental measurements.

塔特拉硅藻数据库（POL_SLOV训练集）中包含了位于塔特拉山波兰和斯洛伐克部分的湖泊。33个湖泊表层沉积物中硅藻与水化学之间的关系是定量pH重建的统计和数值技术的基础。使用高山（AL：PE）和POL_SLOV训练集对过去的水pH进行重建，以比较Tatra湖泊数据库的可靠性。结果表明POL_SLOV训练集具有更好的统计参数（R ²高出0.16，RMSE和最大值。与AL：PE训练集相比，偏差分别降低了0.2和0.36）。在Przedni Staw Polski的情况下，POL_SLOV训练集的更好性能尤其明显，与基于AL：PE数据集的推断相比，推断水的pH曲线在1960年代至1990年期间显示出相反的趋势。通过与当前仪器测量结果进行比较，可以确定推断出的pH值的可靠性。
