Selecting future time periods and emissions scenarios:
The slider bar to the right of the figure under Time Period allows the user to adjust the future time period used to calculate the projected change in precipitation. For each time period, the user can also select a future greenhouse gas emissions scenario under Future Emissions Scenario by selecting Moderate Emissions future, Representative Concentration Pathway (RCP) 4.5, or a High Emissions future, RCP 8.5.
Viewing individual locations trends over time:
By holding your mouse over an individual grid cell, a window that shows trends in the seasonal total precipitation will pop up. This data was calculated for each year of the analysis, for each grid cell and will change as you select different metrics, years and future emissions scenarios using the instructions above.
Filtering by geography:
Using the dropdown menu, users should first select a geographic level—the entire watershed, state, county or municipality. A list of states, counties or municipalities will appear, and individual locations can then be selected.
