Description
A characterization of the data, including its intended use and limitations.
Abstract:
Multivariate statistical analysis and geographic information systems were used to delineate homogeneous agroclimate zones for Idaho for the purpose of applying successful dryland agricultural research practices and management decisions throughout these areas of relative climatic uniformity.  Data used to produce the classification are from the Parameter-elevation Regressions on Independent Slopes Model (PRISM), developed at Oregon State University.  PRISM has produced gridded estimates of mean monthly and annual climatic parameters from point data and a digital elevation model (DEM).  Principal components analysis was performed on fifty-five variables including various temperature and precipitation parameters, the number of growing-degree days, the mean annual number of freeze-free days, the mean annual day of first freeze in the fall, and the mean annual day of last freeze in the spring.  Cluster analysis was used to identify sixteen agroclimate zones each having similar climatic conditions regardless of its spatial location.  As a result, successful dryland agricultural practices and management decisions that are based on new technologies and developed for one part of the state may potentially be applied to other parts of the state that fall within the same agroclimate zone.
Purpose:
1. To demonstrate that a combination of geographic information systems (GIS) and multivariate statistical procedures can be used to map climate using data from the Parameter-elevation Regressions on Independent Slopes Model (PRISM).

2. To delineate agroclimate zones for the purpose of applying successful dryland agricultural research management practices throughout areas of relative climatic uniformity.

Process description:
It is beyond the scope of this metadata to describe in detail the procedures used to create this coverage.  A full description of the methods used can be found at http://www.uidaho.edu/~climate.  In general, the procedures used were:

1. Downloaded PRISM data from Oregon Climate Services web site (http://www.ocs.orst.edu/prism/prism_new.html):
- Mean temperature
- Minimum temperature
- Maximum temperature
- Precipitation
- Growing-degree days
- Day of spring freeze
- Day of fall freeze
- Growing season length

2. ARC/INFO GIS was used to extract information needed for agroclimate classification.  The ASCII data were converted to ARC/INFO grids and projected to IDTM.  The fifty-five grids used in the classification were created from various seasonal temperature and precipitation parameters, the seasonal number of growing-degree days, the mean annual number of freeze-free days, the mean annual day of first freeze in the fall, and the mean annual day of last freeze in the spring.

3. The data were exported to a statistical software package and PCA and cluster analysis were performed.  A georeferenced ASCII file was created that contained the sixteen cluster groupings (i.e. the agroclimate zones).

4. The GIS was then used to display the agroclimate zones.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additonal information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
