Seasonal effects in the long-term correction of short-term wind measurements using reanalysis data [PDF]

open access: yesWind Energy Science, 2021
Measure–correlate–predict (MCP) approaches are often used to correct wind measurements to the long-term wind conditions on-site. This paper investigates systematic errors in MCP-based long-term corrections which occur if the measurement on-site covers ...
