A 30-year period is used to describe the present climate since it is enough time to filter out short-term fluctuations but is not dominated by any long-term trend in the climate. The frost-free period is the number of days between the last date of 00C in the spring and the first date of 00C in the fall. Frost free periods in Alberta vary from 125 days in the south to less than 85 days in higher elevation, non-agricultural areas.The frost-free period is presented as days above 0°C in the following classes: less than 85, 85 to 95, 95 to 105, 105 to 115, 115 to 125 and greater than 125. This resource was created using ArcGIS. purpose: Provides users with representation of the frost-free period as the number of days between the last date of 00C in the spring and the first date of 00C in the fall. The data is suitable for indexing and analysis purposes. The frost-free provides a measure of the period during which plant growth should occur uninterrupted by frost, and it provides a way to compare growing conditions within the province. When selecting new crop types and varieties, producers consider climate characteristics including the length of the frost-free period and the expected date of fall frost. It is important information for producers for planning purposes, indication where the advantages of growing a particular crop may outweigh the risk of occasional frost damage. The yield potential of some crops is closely related to the growing season length. Generally, for the production of marketable grain crops, the frost-free period to be greater than 100 days. status: MD_ProgressCode: completed resourceMaintenance: MD_MaintenanceInformation: maintenanceAndUpdateFrequency: MD_MaintenanceFrequencyCode: asNeeded descriptiveKeywords: MD_Keywords: keyword: Alberta type: MD_KeywordTypeCode: place descriptiveKeywords: MD_Keywords: keyword: Meteorology keyword: Weather keyword: climate keyword: freezing keyword: growing period type: MD_KeywordTypeCode: theme thesaurusName: CI_Citation: title: Agrovoc date: CI_Date: date: 2016-01-21 dateType: CI_DateTypeCode: revision citedResponsibleParty: missing descriptiveKeywords: MD_Keywords: keyword: Downloadable Data thesaurusName: uuidref: 723f6998-058e-11dc-8314-0800200c9a66 resourceConstraints: MD_LegalConstraints: useConstraints: MD_RestrictionCode: license otherConstraints: Your use of this information will be governed by the terms of the Open Government Licence - Alberta, in force as of the date you accessed the information , found at http://open.alberta.ca/licence resourceConstraints: MD_LegalConstraints: accessConstraints: MD_RestrictionCode: otherRestrictions otherConstraints: To access the data you must agree to the terms of the Open Government Licence - Alberta found at http://open.alberta.ca/licence resourceConstraints: MD_LegalConstraints: useLimitation: Distribution Liability: Under the terms of the Open Government Licence - Alberta, the Information is licensed as is, and the Information Provider excludes all representations, warranties, obligations, and liabilities, whether express or implied, to the maximum extent permitted by law.

Frost-free of Alberta, 1971 to 2000, is found in the Agroclimatic Atlas of Alberta, 1971 to 2000 (Chetner and the Agroclimatic Atlas Working Group, 2003). The map was based on 1971 to 2000 data from Environment Canada, Alberta Environment and the United States National Climate Data Center. These agencies collect data from over 1200 climate stations in Alberta and 1400 stations in neighboring provinces, territories and states. The stations collect daily temperature and precipitation information. Environment Canada receives the majority of the data from the federal and provincial networks and performs quality control on the data. Data from the United States stations is provided by the U.S. National Climate Data Center.
                  
The temperature data collected was used to derive frost dates and, in turn, the frost-free period. Temperature 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. dateTime: 2003-01-01T00:00:00 source: LI_Source: description: Information on the Frost-free Period of Alberta sourceCitation: CI_Citation: title: Agroclimatic Atlas of Alberta, 1971 to 2000 date: CI_Date: date: 2003-09-09 dateType: CI_DateTypeCode: publication identifier: MD_Identifier: code: Agdex 071-1 citedResponsibleParty: CI_ResponsibleParty: organisationName: Alberta Agriculture and Food contactInfo: CI_Contact: address: CI_Address: city: Edmonton administrativeArea: Alberta role: CI_RoleCode: publisher citedResponsibleParty: CI_ResponsibleParty: individualName: Chetner, S. and the Agroclimatic Atlas Working Group contactInfo: missing role: CI_RoleCode: author otherCitationDetails: Paper copies (Agdex 071-1) are available from the AF Publications office in Edmonton by calling (780) 427-0391, or 1-800-292-5697 toll-free in Canada. metadataMaintenance: MD_MaintenanceInformation: maintenanceAndUpdateFrequency: MD_MaintenanceFrequencyCode: notPlanned
