Provides detailed information about variables in the CHELSA (Climatologies at High Resolution for the Earth's Land Surface Areas) dataset, including names, units, and descriptions.
Format
A tibble with 47 rows and 6 columns:
var_name(character): Variable short name, e.g., "bio1".long_name(character): Full variable name, e.g., "mean annual air temperature".unit(character): Measurement unit, e.g., "°C".scale(numeric): Scale factor applied to the variable.offset(numeric): Offset value applied to the variable.explanation(character): Description of the variable.
