3TIER Releases 5km Wind Map of the World

3TIER has unveiled a 5-kilometer resolution global wind map based on one of the most accurate and comprehensive datasets ever created of global wind resources and their spatial and temporal variability. 3TIER unveiled its map and dataset at the 14th UN Climate Change Conference in Pozna?, Poland, as part of the Global Wind Energy Council’s (GWEC) “Wind Power Works” campaign.

“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.”
To produce the 5km wind map and the underlying dataset, 3TIER implemented a physical-statistical modeling approach. Unlike traditional models that 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, the company said.

The company said that it ran its model through a 10-year simulation across the world’s landmass at a 5 km resolution. The results then were calibrated and validated with observational data to create the final dataset and, ultimately, the world wind map.
“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 said. “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.”
In October, 3TIER released the first comprehensive, contiguous, high-resolution solar map for the entire Western Hemisphere. The dataset 3TIER developed to create the solar map is approximately three times the resolution of existing industry solar data standards for the United States and is the only database today that covers all of North, Central and South America.
