## Flow Diagram: Wind Electricity Simulation and Correction Factors
### Overview
The image is a flow diagram illustrating the process of data acquisition, calibration, validation, and derivation of correction factors for wind electricity simulation. The diagram is divided into four main stages, each represented by a colored box: data acquisition, calibration, validation, and derivation. Arrows indicate the flow of data between these stages.
### Components/Axes
The diagram consists of four main sections, labeled (a) through (d):
* **(a) Data acquisition, classification and processing (Blue box):** This section outlines the initial data sources.
* **(b) Calibration and cross-validation of wind speeds (Green box):** This section describes the calibration process.
* **(c) Validation of wind electricity simulation (Orange box):** This section details the validation process.
* **(d) Deriving national correction factors (Purple box):** This section describes the derivation of correction factors.
Each section contains rounded rectangles representing specific data or processes. Arrows connect these rectangles to show the flow of information.
