Zhenyu Tan et al.
At the end of 2019, the very first COVID-19 coronavirus infection was reported and then it spread across the world just like wildfires. From late January to March 2020, most cities and villages in China were locked down, and consequently, h...
Monitoring orbital precession of EO-1 Hyperion with three atmospheric correction models in the Libya-4 PICS [0.03%]
使用Libya-4 PICS的三种大气校正模型监测EO-1 Hyperion的轨道进动
Christopher Neigh,Joel McCorkel,Petya Campbell et al.
Christopher Neigh et al.
Spaceborne spectrometers require spectral-temporal stability characterization to aid validation of derived data products. EO-1 began orbital precession in 2011 after exhausting onboard fuel resources. In the Libya-4 Pseudo Invariant Calibra...
