Wind Resouces in 100m height at Lillgrunden, Sweden. GASP data accessed through windPRO 3.5.

Introduction

"RASP Sweden" is short for "Regional Atlas of Siting Parameters for Sweden". It is a calibrated regional wind atlas dataset with the following key features:

  • Regional Coverage - Sweden
  • Calibrated parmeters - with coverage at 250m resolution
  • Available parameters are wind resources, siting parameters & turbine design classification
  • Builds on DTU GWA (Global Wind Atlas) datasets and EMD's Load Response technology
  • Is developed in the GASP project - joint R&D project by EMD and DTU

Dataset Overview

  • Spatial coverage:
    • Onshore: Swedish National Coverage
    • Offshore: Areas are covered up to approximately 50 km from the coastline
  • Resolution:
    • Horizontal: 250m in grid resolution
    • Vertical: 100m and 150m as vertical levels
  • Data-type: Atlas
  • Coordinate system: Geographical coordinates (EPSG: 4326) in original data
  • Version: 0.3 (this dataset is a demonstration dataset, and it is currently in beta release)

Availability from within EMD software

  • windPRO: In 'Data' menu click '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.
    • The .siteres file can be used in PARK, Site Compliance, Load Response and Optimization calculations.
  • windPROSPECTING: GASP data is available through the data-tab named 'Site-prospecting'. Free access to windPROSPECTING - here.
    • windprospecting offers spatial view of omnidirectinal parameters and detailed point-data with directional results and statistics.
  • 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

For the list of parameters available - please see the GASP-Global dataset.
The RASP-Sweden set of parameters are similar to the GASP-Global, however the vertical dimension is currently limited to 100m and 150m a.g.l. (as opposed to the GASP-Global with 3 heights of 50m, 100m and 150m).

Attribution

If data from this dataset is used within any private or public disseminations, then EMD and its data providers must be acknowledged.

RASP-Sweden version 0.3 is a regional atlas of site parameters accessible via windprospecting.com, windPRO and EMD-API.
This dataset builds and extends upon the GASP 1.0 dataset - developed by EMD and DTU.
