What are the climatic zones of the Cauca River Valley?

The intensity of the gray tones defines the scale from higher (darker) to lower (lighter) for each variable. 


Global radiation: direct radiation (that which falls on a surface directly from the sun) + diffuse radiation (that which arrives after being reflected or is emitted by the molecules after being heated by the absorption effect of solar radiation).


Additional information on climate analysis can be consulted in the Cenicaña library and through there is access to climate data registered by the RMA.
