Multiple Angle Observations Would Benefit Visible Band Remote Sensing Using Night Lights

The spatial and angular emission patterns of artificial natural light emitted, scattered, reflected from the Earth at night are far more complex than those for scattered solar radiation during daytime. In this commentary, we use examples to show that there is additional information contained in distribution emitted light. We argue could be used improve existing remote sensing retrievals based on lights, some cases make entirely new analyses possible. This work will challenging, so hope article encourage researchers funding agencies pursue further study how multi-angle views can analyzed or acquired.
