What is this tool?

Generates time series of basic statistics
(max, min, sum, mean) over custom search areas

What datasets can be used?

Works with historic station data as well as gridded datasets

SEE STATION_NETWORKS

SEE GRIDDED DATASETS

Temporal Resolution
Daily
Observed Quantities
Station/Gridded:
Precipitation (in/mm)
Maximum Temperature (F/C), Minimum Temperature (F/C)
Station only:
Observation Time Temperature (F/C)
Snowfall (in/mm), Snow Depth (in/mm)
Derived Quantities
Station/Gridded:
Heating/Cooling/Growing Degree Days (F/C)
Average Temperature (F/C)

All data sets are made available through the ACIS system.

Generate Time Series, Download Data and Graphs

• Individual Station, List of Stations: Search by station IDs or names.
• State: US state abbreviation.
• County(FIPS), County Warning Area, Climate Division, Basin: Search by code or name or use the map.
• Using the map to find
  County/County Warning Area/Climate Division/Basin codes
• Chose the US state from the dropdown above the map.
• Wait until the new map has loaded.
• Once the map overlays are visible,
  click on an area on the map to see the name and ID of that area.
• Note that clicking on an area on the map
  will populate the main form with the corresponding identifier.
• Custom Shape: Use the map interface to draw a custom polygon.
• Using the map interface to draw a custom shape
• You can place a marker on the map or
  draw a rectangle, circle or polygon.
  Click on the appropriate icon in the legend on the top of the map.
• Marker: Point and click on the map.
• Rectangle: Point at a corner of your rectangle, click, hold and drag in the desired direction.
• Circle: Point at the center of your circle, click, hold and drag outwards.
• Polygon: Point and click at each corner of your polygon.
  Finish by double clicking at the final point
  or by clicking on the first point of your polygon.

• yyyymmdd
• yyyy-mm-dd
• yyyy/mm/dd

Choose one or more climate variables from the drop down menu.
Only a limited set of climate variables are available for gridded data.

Note: degree day calculations are preformed
with base temperatures in Fahrenheit.


• 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

• Maximum: Finds the maximum value over the area.
• Minimum: Finds the minimum value over the area.
• Mean: Finds the average value over the area.
• Sum: Finds the sum of the values over the area.
