3D Radiation-Topography Interaction Warms Up Tibetan Plateau
3-D radiation-topography interaction, which can increase the sunlight absorption by the surface, is missing in all climate models, causing strong cold biases over the Tibetan Plateau.

Improving Retrievals for Vertically Inhomogeneous Warm Clouds
Cloud droplet size changes with height, but passive sensors are virtually blind to see it; however, combining passive with active sensors helps profile it in vertically inhomogeneous warm clouds.

What Drives Surface Winds in a Deep Valley?
Surface winds in a Himalayan valley are found to vary daily and seasonally due to factors including pressure gradient, advection, turbulent vertical mixing, and the presence of glaciers.

How Brown Carbon and Coatings on Black Carbon Affect Absorption
While ambient black carbon absorption is shown largely independent of coatings, distinct types of atmospheric brown carbon coexist, deriving from primary emissions and secondary processing.
