Description:
Abstract: 30 Year Average Winds; Speed & Direction Averaged by Month from 1960 to 1989.
Purpose: The monthly wind speed & direction averages were used with other weather data to glean general climatological information for the Basin.
Supplemental Information:
Theme ID: 861
Theme Group: ATMOSPHERIC GROUP
Theme Abbreviation: ATMWEAAW
Surface winds are dependent upon underlying topographic, surface pressure, and surface thermal gradients.
ICBEMP staff in Portland, OR combined original USFS Intermountain Fire Sciences Lab (Missoula, MT) grids, based on monthly averages of wind speed and direction over 30 years, into two grids; one represents wind speed and one represents wind direction.
For vector data, see BVBWEAAW.

Attribute Accuracy:
Attribute Accuracy Report:
Topology and attributes for this theme were manually checked by comparing plots of the processed data against original materials. Attribute accuracy information for source materials were not collected since acquisition of source data pre-dated FGDC metadata standards.
Logical Consistency Report: Not applicable to raster data.
Completeness Report:
Surface winds were modeled using a single layer, hydrostatic wind model (WINFLO) that was modified and adapted for use in the ICBEMP by the PNW Research Station. Surface winds were calculated by month from 1960 through 1989. Speed was calculated within 1 meter/second and direction within 1 degree. The layer is accurate within about 3 meters/second and 20 degrees.

Please specify requested datasets by placing a checkmark in the space provided on the Available Data List.
Spatial data are released in Unix ARC/INFO export format. ARCVIEW files are made available when applicable. The digital data are provided on 8mm tape unless otherwise specified. Please specify special instructions for export format and tape density on the request form.
The Bureau of Land Management (BLM) Oregon State Office will telephone the requester to advise the cost of requested data. The requested data are mailed to the requester after payment has been received by the BLM.
Cost is based on a manual labor charge of $20.00 per hour (prorated), cost of the tape(s), and size of the map/plot(s). Digital data are provided on 8mm tape (cost $9.00) unless special instructions are specified on the request form. Federal offices are provided the information free of charge.
Technical Prerequisites:
Spatial data are released as both compressed Unix-based archive ARC(.TAR.Z) export files and PC-based executable (.EXE) files. Attribute files are released in dBASE IV (.DBF) format as Unix-based archive (.TAR.Z) files and PC-based (.EXE) files. Additionally, databases are released in both dBase IV and Paradox (.DB) format as .TAR.Z and .EXE files. All files within the archive .TAR.Z files and .EXE files follow the 8.3 naming convention to enable use on the Windows 3.1 operating system.
