Solar Radiation Partitioning and Surface Albedo Parameterization in the Hinterland of Taklimakan Desert

open access: yesAdvances in Meteorology, 2019
Surface albedo is one of the key parameters of land surface radiation and energy balance. As surface albedoes for visible and near-infrared solar radiation are quite different, solar radiation partitioning is important to parameterize the total surface ...

Solar radiation pressure augmented deorbiting from high altitude sun-synchronous orbits [PDF]

open access: yes, 2012
This paper discusses the use of solar radiation pressure (SRP) augmented deorbiting to passively remove small satellites from high altitude Sun-synchronous orbits. SRP-augmented deorbiting works by deploying a light-weight reflective inflatable device to
