Title: Annual Total Precipitation 1971-2000
Dataset Publication Date: 2005-09-01
Abstract: The data represents the annual total precipitation in Alberta over the 30-year period from 1971 to 2000. A 30-year period is used to describe the present climate since it is enough time to filter our short-term fluctuations but is not dominated by any long-term trend in the climate. Annual total precipitation refers to rain, snow and other forms of moisture such as hail. Annual precipitation is greatest in the mountains and decreases at lower elevations. In the agricultural areas of the province, 50 to60 percent of annual precipitation generally occurs during the growing season, mostly as rain.Precipitation in any month can be extremely variable with the variability of precipitation being greater in southern Alberta than in the Peace River Region and central Alberta. However, long-term (30-year) data provides a reliable indication of what to expect in any given location. Climate information is used as a long-term planning tool, in selecting a location for a farm or planning a cropping program. Crop producers generally look at the most likely weather conditions rather than the extremes because the key inputs and decisions are made well in advance of achieving results. By combining knowledge of the agricultural operation with knowledge of what is likely to happen (climate), the producer can then decide on the acceptable level of risk due to adverse conditions.

Scope (quality information applies to): Dataset
Data History: Precipitation data collected at climate stations was interpolated between stations and rolled up to a township. In order to avoid the blocky appearance of townships on the map, a township generalization was produced using smoothing procedures of computer graphics software for final presentation on the map. The township generalization used in the map smoothes the look of the data, but townships between recording stations may have slight variations from what is shown on the map.
