Great Lakes Adaptation Data Suite (GLADS)

Through a Data Management Mini-Grant from the Great Lakes Observing System (GLOS), GLISA has created a data suite—the Great Lakes Adaptation Data Suite (GLADS)—that is a compilation of over-land and over-lake observational information within the Great Lakes Basin. GLADS integrates point-based and gridded observational datasets available through the National Centers for Environmental Information (NCEI, formerly NCDC), the Great Lakes Observing System (GLOS), the Great Lakes Environmental Research Laboratory (GLERL), the Great Lakes Aquatic Habitat Framework (GLAHF), and the Great Lakes Evaporation Network (GLEN) into a single Great Lakes Adaptation Data Suite (GLADS). Each of these suites/frameworks of data has proven valuable to their own user networks. GLISA has standardized these regional data sets to the same time step, variables examined, data structure, and quality control processes to make the data more easily accessible and to increase the capacity of researchers to study lake, nearshore, and coastal interactions for climate adaptation efforts.

Data available in the GLADSDatasets included in the initial version of GLADS. Including from a variety of networks: in-situ observations, spatially averaged observations, gridded products of both over-land and over-lake weather and climate.

Datasets in GLADS

Data cover the 8 Great Lakes States (MN, IL, IN, MI, NY, OH, PA, & WI) and portions of Ontario. When available, time steps have been standardized to daily, monthly, seasonal, and annual steps. Gridded products have been resampled to the 1.8 km grid from the GLAHF framework and are available in Georeferenced TIFF files.

Datasets include:

  • GLISA quality-controlled NCEI Global Historical Climatology Network Daily
  • NCEI Climate Divisions
  • NCEI Air Stagnation Data
  • NCEP Climate Forecast System Reanalysis
  • University of Delaware Gridded Air Temperature and Precipitation
  • GLERL Percentage Lake Ice Cover
  • GLERL Lakewide Water Temperature
  • GLERL Master Gauge Water Levels
  • NDBC Standard Meteorological Data
  • GLAHF-compiled USGS Stream Gauges
  • GLAHF-compiled NOAA Coastwatch
  • GLAHF-compiled NOS CO-OPS
  • GLAHF-compiled GLERL GLSEA
  • GLAHF-compiled GLERL Ice Atlas
