How to Download the Data
- Select a variable by using the “Select Option” drop-down menu on the left, and use the map on the right to highlight the area of interest.*
- Select data set variables by checking/unchecking the boxes next to the corresponding variable names.*
- Users can insert specific whole coordinates by filling in the “Longitude” and “Latitude” boxes in the panel.
- Select the period of record under the Time panel by inserting the dates for the “Start Date” and “End Date” options by year (e.g., 2023) or full date (e.g., YYYY-MM-DD)
- Select the option for annual (averaged by year), seasonal (averaged by season), and month (averaged by month) temporal resolutions for the data in the “Dataset Period” drop-down.
- Select the output by using the “File Type” drop-down menu.
- Download the data by clicking the “Download Data” button at the bottom of the panel.
*The precipitation data uses a different grid spacing than the other variables, and this data has a separate option for only precipitation data.
Featured Variables
Important Note: The total precipitation data is available in a different model resolution from the other variables listed. Only select the total precipitation option to view/download this variable’s data.
| Variable | Keyword Option | Description |
| Average Temperature | Average_Temperature_degF | Average_Temperature_degC | Average temperature reported in degrees Fahrenheit (deg F) or Celsius (deg C). |
| Maximum Temperature | Maximum_Temperature_degF | Maximum_Temperature_degC | Maximum temperature reported in degrees Fahrenheit (deg F) or Celsius (deg C). |
| Minimum Temperature | Minimum_Temperature_degF | Minimum_Temperature_degC | Minimum temperature reported in degrees Fahrenheit (deg F) or Celsius (deg C). |
| Precipitation Rate | Precipitation_Rate_inches | Precipitation_Rate_mm | The precipitation rate is given in inches or millimeters (mm). |
| Wind Speed | Wind_Speed_m/s | The time-averaged wind speed was measured in meters per second (m/s) in the Great Lakes region. |
| Total Precipitation | Total_Precipitation_inches | Total_Precipitation_mm | Total precipitation in inches (in) or millimeters (mm). |
Available File Types
These are the file options available from the GLADS.
| File Type | Description |
| Comma Separated Values (CSV) | This option will create output as a delimited text file with values separated by commas. The data is not viewable within the web browser when this data export option is selected. The web browser will typically offer the user the option of opening the file in MS Excel or a similar spreadsheet program for display. |
| Web Output Table (HTML) | This option will display data in a structured table (with variable names and units as headings) in the user’s web browser. |
| Network Common Data Framework (NetCDF) | This option will download the desired data as a NetCDF file. The data is not viewable within the web browser when this data export option is selected. The user will need third-party software supporting this format when saving the file to their computer. |
