The Whole Atmosphere Community Climate Model (WACCM) is used to generate computer simulations of the dynamic processes interacting between the terrestrial and solar systems that impact on Earth's climate.[1] The original model was developed around the turn of the millennium[1] with the most recent iteration, version 6 (WACCM6), released in 2019.[2] The Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM-X) extends the model to space weather and space climate.[3]
