Title: Evapotranspiration Data for Idaho
Originators: Idaho Department of Water Resources, University of Idaho
Publisher: Idaho Department of Water Resources
Publication place: Boise, Idaho USA
Publication date: 2008
Data type: raster digital data
A characterization of the data, including its intended use and limitations.
Evapotranspiration data developed using METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration). METRIC is an image-processing model for computing ET data for large areas from satellite images.  METRIC computes a complete radiation and energy balance for the earth's surface along with fluxes of sensible heat and ET.  METRIC uses digital image data collected by Landsat or other remote sensing satellites measuring visible, near-infrared, and thermal infrared radiation.  METRIC also incorporates USBR AgriMet weather data into the modeling process.  
Dr Rick Allen, Dr. M. Tasumi, and Dr. R. Trezza, of the University of Idaho, developed METRIC by making refinements to the Surface Energy Balance Algorithm for Land (SEBAL).
Digital ET images for water rights, hydrologic models, regional planning.
Supplemental information:
METRIC ET data in Idaho was developed using Landsat 5 or Landsat 7 data.  Most data are in the ERDAS Imagine file format.  Filenames include the path and row of the Landsat images used and the range of dates for seasonal ET data (e.g. p40r30_20000301to1031season_et.img is Landsat path 40 row 30, seasonal ET for the growing season of 3/1/2000 to 10/31/2000).  Monthly images show the month number (e.g. p40r30_200007_et.img is for July of 2000).  Usually about 8 images (one per month) are processed to develop a seasonal ET image.  ET units are millimeters.

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 additional information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.3
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.
