Seasonal Summary
What is this tool?
For each year in the period of record for a station or a valid date range for a grid,
data is temporally summarized over a custom time period specified by Start/End Month/Day.
What datasets are available?
Works with historic station data as well as interpolated gridded datasets

Time period of the request. Format yyyy.
If you chose any of the Degree Day variables,
please specify your base temperature.
Data can be obtained in metric or English units.
-
Note: degree day calculations are preformed
- English:
Temperatures in Fahrenheit
Precipitation/Snow/Pan Evaporation in Inches
Wind Movements in Miles
-
Metric:
Note: native database units are English.
If you choose metric, be aware that data values loose precision
since they are converted from English units and will be rounded.
Temperatures in Celsius
Precipitation/Snow/Pan Evaporation in Millimiter
Degree Days: °C HDD = (5/9) x (°F HDD)
Wind Movements in Kilometers
with base temperatures in Fahrenheit.
Data summary over time period. Options are:
- Maximum: Finds the maximum value over the time period.
- Minimum: Finds the minimum value over the time period.
- Mean: Finds the average value over the time period.
- Sum: Finds the sum of the values over the time period.
Plotting options in panel above the graph
The Threshold parameter on the left top of the panel defines a line on the graph.
Depending on the variable, values below that value will appear in one color (blue or red) on the graph,
values above the threshold will show in the other.
The threshold value defaults to the average of the data plotted.
Add a running mean by checking the checkbox in the top middle of the panel
and choose the appropriate number of years for your running mean.
The top middle of the panel also contains a checkbox to show the average of the data that is plotted.
The right side of the panel has options to show or hide the legend and to change the chart type.
On the Graph
Hover your mouse over a point on the graph to see the date and data value at that point
Click and drag on the graph to zoom in on a particular area.
A "Reset Zoom" button will pop up on the top righ hand side of the graph. This will allow you to reset the zoom to it's default value.
The legend is movable. Just hover your mouse over the double dots, click and move the legend to the desired position.
In the top right corner of the graph you can find print and serevral download options (PNG, JPEG, PDF, SVG).
