CERRA

Spatial domain for the CERRA mesoscale data in windPRO (we cover approx. 300km from the coastline). Image showing average wind speeds at 100m from 2012-2012 - taken from the https://www.windprospecting.com platform.

Introduction

CERRA, is a high resolution hindcast dataset provided by Copernicus. The model holds data at 5.5km resolution and covers central Europe.

Dataset Overview

• Content: Limited feature and spatial-domain subset of the CERRA mesoscale dataset
  (we provide about 973.000 nodes in a distance of approx. 300km from the coastlines).
• Spatial resolution: 5.5km
• Temporal resolution: Timestep 1 hour
• Coverage: See the map to the right
• Period: In windPRO: 20+ years of data from 1999-01-01 to 2021-12-31
  (source data dates back to 1984 from Norwegian Meteorological Institute)
• Update schedule: Unknown (but is is our expectation that data is updated with a 3-4 month of delay from current date, due to ERA5 availability and computational demands).
  We will update this dataset when more recent data becomes available.
  

Dataset Parameters

A total of 80 parameters are available from the CERRA mesoscale data-subset in windPRO.
