Frequently-anticipated questions:

What does this data set describe?

Title: Gridded Wind Parameters of Alaska
Abstract:
This file was created using the MesoMap system which consists of an integrated set of atmospheric simulation models, databases, and computers and storage systems. At the core of MesoMap is MASS (Mesoscale Atmospheric Simulation System), a numerical weather model, which simulates the physics of the atmosphere. MASS is coupled to a simpler wind flow model, WindMap, which is used to refine the spatial resolution of MASS and account for simple localized effects of terrain and surface roughness. MASS simulates weather conditions over a region for 366 historical days randomly selected from a 15-year period. When the runs are finished, the results are input into WindMap. Truewind subsequently validates the wind maps. In addition to the raster wind maps that are created, the final product is a grid of points each containing values for various wind parameters. The points are spaced at 2 kilometers apart and include predicted wind speed frequency distribution, and speed and energy in 16 directions. This information is necessary for the production of a wind rose image at a given point.
Supplemental_Information:
The layers listed below are available as ArcGIS shape files and in Google Earth format. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Layers include: 
AK_rose_wind_data_north     predicted wind speed frequency distribution, wind speed, and wind energy in 16 directions (north, mainland Alaska)
AK_rose_wind_data_south     predicted wind speed frequency distribution, wind speed, and wind energy in 16 directions (south, mainland Alaska)

Why was the data set created?

The purpose of creating this file was to use MesoMap to create high-resolution wind maps and to provide wind resource data in a format enabling the assessment of potential wind development sites in a GIS. By combining a sophisticated numerical weather model capable of simulating large-scale wind patterns with a microscale wind flow model responsive to local terrain and surface conditions, they enable the mapping of wind resources with much greater accuracy than has been possible in the past. In addition, they do not require surface wind data to make accurate predictions. While on-site measurements will be required to confirm the predicted wind resource at any particular location, mesoscale-microscale modeling can greatly reduce the time and cost required to identify and evaluate potential wind project sites.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 2006 (process 1 of 4)
    The MesoMap system creates a wind resource map in several steps. First, the MASS model simulates weather conditions over 366 days selected from a 15-year period. The days are chosen through a stratified random sampling scheme so that each month and season is represented equally in the sample; only the year is randomized. Each simulation generates wind and other weather variables (including temperature, pressure, moisture, turbulent kinetic energy, and heat flux) in three dimensions throughout the model domain, and the information is stored at hourly intervals. When the runs are finished, the results are compiled into summary data files, which are then input into the WindMap program for the final mapping stage. The two main products are usually (1) color-coded maps of mean wind speed and power density at various heights above ground and (2) data files containing wind speed and direction frequency distribution parameters. For the standard MesoMap configuration MASS is run on the following nested grids: First (outer) grid level: 30 km, Second (intermediate) grid level: 8 km, Third (inner) grid level: 2.5 km.

    Written summary of the data processing procedures that are performed on the raw measured data in order to create an annual dataset of "typical" wind speeds, which could then be used to calculate potential power production from wind turbines. There are various methods and reasons for adjusting the raw data, so the purpose of these notes is to document what is typically done in AEA reports. See the associated PDF file, <http://akenergyinventory.org/metadata/WND2006_process.pdf> for more information.

    Formal FGDC metadata (this document) was rewritten for the entire AK wind dataset (K.R. Papp, AEA, 18-Jun, 2009). The original 2006 metadata, each describing an individual layer, have been combined into this single dataset (i.e. north and south gridded wind parameters). The dataset will be viewable/distributed online via the Alaska Energy Data Inventory (<http://akenergyinventory.org>) project.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Raster cell values of the average wind speed (m/s) and wind power (W/m^2) density were computed from the MASS (Mesoscale Atmospheric Simulation System), a numerical weather model, which simulates the physics of the atmosphere. The maps and data can then be compared with land and ocean surface wind measurements, and if significant discrepancies are observed, adjustments to the wind maps can be made. The usual geophysical and meteorological inputs were used. The WindMap program adjusted the wind resource estimates to reflect local topography and surface roughness changes on a grid spacing of 200 m. For the topographical data, we used the National Elevation Dataset, a digital terrain model produced on a 30 m grid by the US Geological Survey (USGS). For the land cover, we used the National Land Cover Dataset, which is derived from Landsat imagery. It was also produced by the USGS on a 30 m grid. In converting from land cover to surface roughness, certain roughness length values were assumed to be typical of conditions in the region. The displacement height is defined as the height at which the wind speed becomes zero in the logarithmic shear formula. For this project, we assumed that the displacement height was 10 times the surface roughness length, which was in turn defined to be approximately 7.5% of the vegetation height. For deciduous forests with a roughness length of 0.9 m, this resulted in a displacement height of 9 m.

  2. How accurate are the geographic locations?

    The WindMap program adjusted the wind resource estimates to reflect local topography and surface roughness changes on a grid spacing of 200 m. The data presented in this data set, however, are spaced at 2-km intervals.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    The shaded raster images display the average wind speed (m/s) and wind power (W/m^2) density for a large portion of mainland Alaska (North Slope and the Aleutians not included).

  5. How consistent are the relationships among the observations, including topology?

    MASS is coupled to a simpler wind flow model, WindMap, which is used to refine the spatial resolution of MASS and account for simple localized effects of terrain and surface roughness. MASS simulates weather conditions over a region for 366 historical days randomly selected from a 15-year period. When the runs are finished, the results are input into WindMap. Truewind subsequently validates the wind maps.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints:
This report, map, and/or data set have been published as part of the Alaska Energy Data Inventory (AEDI) project. The vector layers may be accessed and downloaded at the user's convenience. All of the data are available directly from AWS Truewind, LLC.
Use_Constraints:
This data was created by AWS Truewind using the MesoMap system and historical weather data. Although it is believed to represent an accurate overall picture of the wind energy resource, estimates at any location should be confirmed by measurement. Please site AWS Truewind, LLC when using this data.
