radar_sites Radar site point data USFWS Great Lakes Migration Decision Support Tool "This is a point feature collating data and location information for 49 radar sites (27 spring and 22 fall) around the Great Lakes collected by the U.S. Fish and Wildlife Service's radar team. See Supplementry Information for more details. The purpose of this dataset is to provide a information in aerial migration across the Upper Midwest Great Lakes region on a site-by-site basis. This dataset is be used to build other predictive layers which can be used to identify general areas of greater and lesser airspace use by birds and bats. In addition, this dataset also provides information on directional movement of birds and bats as they migrate through the basin, allowing to the identification of lake crossing locations as well as areas where migrants avoid crossing the lakes. " Site -specific radar data for migrating birds and bats, including: direction, level of effort, peak and average density of migrants. Densities of migrants from common subsets of data across sites the radar are included to improve intercomparability. -93.617325 -74.236706 40.485244 48.245784 2011-01-01 2018-12-31 "Target passage rate (TPR) values in this layer are not a directly comparable measurement of migration intensity among sites. Data was collected by two mobile radar units from various sites on the U.S. side of the Great Lakes basin between 2011 and 2018, and differs in radar interference (""clutter"") due to site specific effects. Likewise, directional movement represents an average, and may mask mixtures of several distinct directional movements.
