title: LAGOS-NE-LIMNO v1.087.3: A module for LAGOS-NE, a multi-scaled geospatial and temporal database of lake ecological context and water quality for thousands of U.S. Lakes: 1925-2013

description: This data package, LAGOS-NE-LIMNO v1.087.3, is 1 of 5 data packages
 associated with the LAGOS-NE database-- the LAke multi-scaled
 GeOSpatial and temporal database. With this release, only this data
 package is being updated and users are expected to use prior releases
 of the other types of data. Please see the attached additional
 documentation for a full description of the changes that have been
 made for this new release.The data packages that make up LAGOS-NE
 include the following information on lakes and reservoirs in 17
 lake-rich states in the Northeastern and upper Midwestern U.S. (1)
 LAGOS-NE-LOCUS v1.01: lake location and physical characteristics for
 all lakes greater than one hectare. (2) LAGOS-NE-GEO v1.05: ecological
 context (i.e., the land use, geologic, climatic, and hydrologic
 setting of lakes) for all lakes and for all spatial resolutions, also
 called ‘zones’ (i.e., ecoregions, states, counties). 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 v1.087.3: in-situ measurements of lake water
 quality 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.
 This module includes variables that are most commonly measured by
 state agencies and researchers for studying eutrophication. For each
 water quality data value, we also include metadata related to the
 sampling program, methods, qualifiers with data flags from the
 original program (qual, not standardized for LAGOS-NE), censor codes
 from our quality control procedures (censorcode, standardized for
 LAGOS-NE), and the date of each sample. (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-RAWDATA: the original 87 datasets of lake water quality prior
 to processing, the R code that converts the original data formats into
 LAGOS-NE data format, and the log file from this procedure to create
 LAGOS-NE. This latter data package supports the reproducibility of the
 LAGOS-NE-LIMNO data module. Citation for the full documentation of
