Space weathering effects in Diviner Lunar Radiometer multispectral infrared measurements of the lunar Christiansen Feature: Characteristics and mitigation
We find that the lunar Christiansen Feature is influenced by space weathering. Albedo-dependent thermal gradients are the likely cause of the observed effect. Composition is also demonstrated to influence the Christiansen Feature. Space weathering can be partly removed from Diviner data using an independent maturity index.
