3TIER releases 5km world wind map

4 Dec 2008

Renewable energy assessment and forecasting company 3TIER released a 5km resolution global wind map.

‘This map is intended to accelerate the development of wind energy by quantifying the value of the wind resource at any location around the world,’ said Kenneth Westrick, CEO and founder of 3TIER.

‘The underlying dataset provides the information developers, financiers and governments need to target the best regions in the world for data collection and higher resolution studies. In short, this map and dataset shortens the process needed to make sound decisions about where to invest in wind energy generation.’

To produce the 5 km wind map and the underlying dataset, 3TIER implemented a physical-statistical modeling approach, the company said.

Unlike traditional models that merely interpolate observed wind speeds between widely dispersed points, 3TIER’s system integrates statistical methods with the power of physical-based models, which simulate the interaction between the atmosphere and the earth’s surface, to create a more robust and accurate wind climatology.

‘Our model produced more than a petabyte of data, which was combined with available observations to create the richest, most accurate and quantifiable dataset available at the global scale,’ Westrick added. ‘This project took nearly a year to complete, and the data shows we achieved our goal of finding the optimal blend between computer modeling technologies and observations.’

3TIER also is mapping the world’s solar resources. In October, 3TIER released the first comprehensive, contiguous, high-resolution solar map for the entire Western Hemisphere.

‘To tackle the issues of dwindling fossil fuel supplies, growing energy demand, energy security, and climate change, an integrated approach to alternative energy is critical,’ Westrick said. ‘Through our REmapping the World initiative, we want to help change the way we look at the world’s energy sources.’

3TIER provides assessment and forecasting services for wind, hydro and solar energy projects. 3TIER uses its knowledge about weather, climate and their impacts
