<p>Climate change and land use change have been shown to influence lake temperatures and water clarity in different ways. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we focused on improving prediction accuracy for daily water temperature profiles and optical habitat in 881 lakes in Minnesota during 1980-2018. <br/> <br/>The data are organized into these items:</p> <ol> <li><a href="https://www.sciencebase.gov/catalog/item/5e5c1c1ce4b01d50924f27e7">Lake Information</a> - A lake metadata file and one shapefile of polygons for all 881 lakes in this study</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e5d0b68e4b01d50924f2b32">Observations</a> - Temperature observations the lakes used in this study</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e5c1c36e4b01d50924f27ea">Model Configurations</a> - Model parameters</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e5d0b96e4b01d50924f2b34">Model Inputs</a> - Data used to drive predictive models</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e5d0bb9e4b01d50924f2b36">Model Predictions</a> - Predictions for water temperature and near-surface irradiance</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e774324e4b01d509270e29f">Model Evaluation</a> - Evaluation of model performance for water temperature predictions</li> <li><a href="https://www.sciencebase.gov/catalog/item/5e774355e4b01d509270e2a1">Habitat Estimates</a> - Estimates of thermal habitat, optical habitat, and thermal-optical habitat area</li> <br/> <p>This research was funded by the Department of the Interior Northeast and North Central Climate Adaptation Science Centers, a Midwest Glacial Lakes Fish Habitat Partnership grant through F&WS Access to computing facilities was provided by USGS Advanced Research Computing, USGS Yeti Supercomputer (https://doi.org/10.5066/F7D798MJ).
