Introduction

GASP Global is "GASP 1.0 - Global of Atlas of Siting Parameters", with the following key features:

  • Global 250m wind resources, siting parameters & turbine design class
  • Builds on GWA3.0 and other sources
  • A joint project by EMD and DTU

Dataset Overview

  • Spatial coverage: Global (offshore areas are covered up to 200 km from the coastline)
  • Resolution:
    • Horizontal: 250m in grid resolution
    • Vertical: 50m, 100m and 150m as vertical levels
  • Data-type: Atlas
  • Coordinate system: Geographical coordinates (EPSG: 4326) in original data
  • Version: 1.0


Availability from within EMD software

  • windPRO: Click 'Data' -> 'Siting parameters (GASP etc)' to access the download tool. Data is loaded into a result layer with a .siteres file acting as the data-container.
  • windPROSPECTING: GASP data is available through the data-tab named 'Site-prospecting'. Access to windPROSPECTING - here.
  • EMD-API: Read more at the dedicated wiki-page for our Global Atlas Data Services - here. If you are accessing the GASP data from within the EMD-API, you will use the parameter group-names in order to request specific data-packages [resource-omni, resource-sector, siting-extremes, siting-fatigue-omni, siting-fatigue-sector, turbine-fatigue, turbine-fatigue-recommend, turbine-extreme, turbine-extreme-recommend].

Parameters and Dimensions

A very wide range of omnidirectional and sectorwise parameters are available from the Global Atlas of Siting Parameters (GASP) - including wind resources, extremes, siting parameters and turbine design classes. The tables below provides an overview of all parameters available and at which dimensions that they are available. We have used the following dimensions for the GASP parameters: The first four (longitude, latitude, height and sector) are used for the basic paraters; the last three (ws_class, iec_class and turbine_component) are used for the turbine design classification - and are releated to the IEC61400-1 code and the aeroelastic load model.Please note that not all dimensions are relevant or used for every GASP parameter.

Table: List of dimensions in GASP data.
Dimension Abbreviation Unit Range
longitude lon deg 180 to -180
latitude lat deg 90 to -90
height h m 50,100,150
sector s deg 0,30,...,330
ws_class wcl I,II,III,T
iec_class iecc IA+, IA,...IIIC
turbine_component tc 0,1,2,3

Parameters: Wind Resources

The two tables below show the GASP parameters for wind resources data, given omnidirectional data [resource-omni] and sectorwise data [resource-sector].

Table: Resource / Atmospheric Omni-directional Parameters [resource-omni]
Variable Description Unit Dimensions

weib_k Wind distribution: k (shape) parameter in Weibull distribution lon, lat, h
wsp Wind speed - annual average m/s lon, lat, h
wpd Wind power density – annual average W/m2 lon, lat, h

Table: Resource / Atmospheric Sector-wise Parameters [resource-sector]
Variable Description Unit Dimensions

Parameters: Siting Classification - Wind Extremes

The two tables below show the GASP parameters for the extreme event data. Please note that this extreme data is only available as omnidirectional parameters.

Table: Siting Parameters – Extremes [siting-extremes]
Variable Description Unit Dimensions
air_dens_p98 Air density at 98th percentile of wind speed kg/m3 lon, lat, h
