Data for: Delineating the relative contribution of climate related variables to chlorophyll-a and phytoplankton biomass in lakes using the ERA5-Land climate reanalysis data

The datasets contain 640 measurements of chlorophyll-a concentration and 452 measurements of phytoplankton biomass from 51 water bodies of Greece. The measurements were collected from 2013 to 2016 under the National Lake Monitoring Programme according to the implementation of the Water Framework Directive.

The data are freely accessible in the following site: biodiversity-info.gr/index.php/el/lakes-data. In addition they contain ERA5-Land climate and lake related variables on average monthly basis.Theextraction was conducted for the nearest grid cell to the centroid of the lake applying the nearest-neighbor interpolation algorithm. Specifically, we extracted the following variables: zonal component of the 10-m wind, meridional component of the 10-m wind, total (surface and subsurface) runoff, total precipitation, air temperature, lake bottom temperature, lake mix-layer temperature, lake mix-layer depth, lake total-layer temperature, and lake shape factor.
