Data Selection & Graph Options
Use these options to change the map display and the parameters that are displayed on the graph. To view the graph for a particular station, click on the marker or circle that represents the station of interest.
A graph will then popup in a new window displaying the observed data along with plots for the mean, state average, standard deviation, and linear trend line.
NOTE:
- Temperature and precipitation data is only available through 2005 for U.S. stations and 2004 for stations in Canada.
- SWE data is only available from 1930 - 2006.
- Under graph options, when state average is selected, it will graph state mean temperatures and precipitation. State averages are not available for max. temperature, min. temperature,
SWE, and stations in Canada.
- If the graph does not appear, you may need to temporarily disable your popup blocking software.
