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

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
