# Clima Dataframe

**Clima** calculates new variables and creates a new **dataframe** containing the variables already inside the original EPW files and other we calculate. Users can overlay all the variables on the [sun path](/clima/documentation/tabs-explained/sun-and-cloud.md), on the [psychrometric chart](/clima/documentation/tabs-explained/psychrometric-chart.md), and on the customizable graphs in the [data explorer](/clima/documentation/tabs-explained/data-explorer.md).

All the variables in the new Clima dataframe are listed below.
