This data package, LAGOS-NE-LIMNO v1.087.1, contains in-situ measurements of lake water quality (i.e variables that are most commonly measured by state agencies and researchers for studying eutrophication) from the past three decades for approximately 2,600-12,000 lakes, depending on the variable. This module was created by harmonizing 87 water quality datasets from federal, state, tribal, and non-profit agencies, university researchers, and citizen scientists.
The data package is 1 of 5 data packages associated with the LAGOS-NE database– the LAke multi-scaled GeOSpatial and temporal database (https://lagoslakes.org). Three of the data packages each contain different types of data for 51,101 lakes and reservoirs larger than 4 ha in 17 lake-rich U.S. states to support research on thousands of lakes. These three packages are: (1) LAGOS-NE-LOCUS v1.01: lake location and physical characteristics for all lakes. (2) LAGOS-NE-GEO v1.05: ecological context (i.e., the land use, geologic, climatic, and hydrologic setting of lakes) for all lakes. These geospatial data were created by processing national-scale and publicly-accessible datasets to quantify numerous metrics at multiple spatial resolutions. (3) LAGOS-NE-LIMNO v1.087.1: the lake water quality data described above. The other two data packages contain supporting data for the LAGOS-NE database: (4) LAGOS-NE-GIS v1.0: the GIS data layers for lakes, wetlands, and streams, as well as the spatial resolutions that were used to create the LAGOS-NE-GEO module. (5) LAGOS-NE-ORIGINAL LIMNO data packages: the original 87 datasets of lake water quality that were processed into the LAGOS-NE data format, the R code that converts the original data formats into LAGOS-NE data format, and the log file from this procedure to convert the dataset to be loaded into LAGOS-NE. This latter data package supports the reproducibility of LAGOS-NE-LIMNO. A list of the LAGOS-NE-ORIGINAL LIMNO data packages, along with a link to their EDI repository landing pages, is included in the LAGOS-NE-LIMNO metadata provenance information.
