| | Merv Watters owns an agrochemical company that wants to promote a new herbicide that controls Kochia (Kochia Scoparia) in cereal crops. Kochia is a weed found in very dry areas. He needs to find the driest areas in the province to focus his market launch.
.
 | Merv wants to use the Climate Mapper to learn the following:
- In the last 10 years, what areas in Alberta had consistently low precipitation?
The climate database of ACIS contains over 256 million climate records dating from 1901 until 2003. Merv can create and print over 104 precipitation maps.
Process:
- Select the Climate Mapper
- Select these choices from the drop down menu under query:
Step 1: Precipitation
Step 2: 1993 (under Year) and Year (under Grouping)
- Click on "Get Data and Refresh Map".
- Click the "Print" icon near the top of the map.
- In the pop-up box that appears, type "Precipitation for 1993 (mm)" and click "okay".
- In the new window that appears, select, "File" - "Print".
- Repeat these steps for each year.
This map breaks down the number of growing days in each region of the province, based on data collected between 1971 and 2000.
In the last 10 years, what areas in Alberta had consistently low precipitation?
From the 1993 map, Merv can see that the driest areas were east of Calgary, and areas near Oyen, Lloydminster, the Peace River, and Fort McMurray. Merv will need to view a map for each year to determine which areas have consistently low precipitation.
