The files in this repository were created using code that is available in the growth window GitHub repository (https://github.com/hfadams/growth_window) and in Zenodo (https://doi.org/10.5281/zenodo.5171442), which was used to standardize and compile a dataset of in situ chlorophyll-a data and related water quality data and for lakes at or above 40° N across the Northern hemisphere. Original data files are not included in this repository but can be found by following the links in the data sources tables in the SHARING/ACCESS INFORMATION section in the README.

The chlorophyll-a growth window dataset contains chlorophyll-a rate of increase along with mean water quality variables (i.e., surface water temperature, nutrients, and solar radiation (SSR)) during periods of rapid algal growth referred to as the growth window. Growth windows were defined based on the rate of change in the fluctuating chlorophyll-a concentration sampled over the year, and categorized as occurring in the spring, summer, or as a "single" growth window when there was one main period of growth. Additional lake parameters were included from the HydroLAKES and HydroATLAS databases, and trophic status index (TSI) was calculated from chlorophyll-a concentrations.

This dataset is intended to be used to explore trends between changing environmental conditions and lake productivity. However, as a compiled dataset, the growth window data is based on lakes samples collected from a variety of organizations with differing methods. Great care was taken to standardize the data and provide all relevant metadata wherever possible.
