RASP Sweden

Wind Resouces in 100m height for Sweden. RASP-Sweden data accessed through windPROSPECTING.

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 250m grid resolution
• Parameters availavble are within 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 - and up to 50km from Swedish borders
  • 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.
