# Specialized charts

**In this document**

You'll learn how to read the two remaining charts in the project's Analysis section: the wind speed and wind direction rose, and the monthly ground surface albedo averages available under the environmental category.

The **specialized charts** included in the Solagis Evaluate’s [Analysis section](/v1/docs/data-analysis) cover two parameters that use their own visualisations rather than the standard time-step histograms: wind, shown as a directional rose, and ground surface albedo, shown as monthly averages.

For the other chart groups and an introduction to the Analysis section, see [How to read the charts](/v1/docs/how-to-read-the-charts).

## Wind speed and wind direction

This chart illustrates the direction and speed of the wind at the location. It is represented by a **circle** depicting the **directions** (North, East, South, West) with intermediary directions in between.

Different **colors represent** different **wind speeds** (1), and the **direction** is indicated by its placement within the chart.

## Ground surface albedo

The chart represents the monthly ground surface albedo averages for the whole time series and is available under the **environmental category** only.

### How to use it

Albedo values can help you establish the reflectivity of the surrounding area and make more informed decisions when selecting the PV module type.
