Table 1: The first 25 lines of synthetic data, including lake chlorophyll-a data and local climate. The are 352 lines, as 352 samples in total. The format of this file is csv.
Table 2: The modified data used for Nonmetric multidimensional scaling (NMDS). Some columns which are not related to this study were removed to simplify the steps. Only 25 rows are shown here, but the original data has 352 rows. (Table 8,9)
Table 3: The modified data for the growth of chlorophyll-a and climate factors at Windermere - north basin, United Kingdom, from 1064 to 2009. Only 25 rows are shown here, but the original data has 46 rows. (Table 10, 11)
