Night Lights for visible Blue Light

by ramazanbora » Tue Apr 18, 2023 9:59 am America/New_York

Is there a product similar to the VNP46 line such that it shows radiances in the visible spectrum such as M3 band that measures the blue light. What I am trying to get at is basically having a proxy for locating emergency vehicles that have blue lights on them.

No, there is no such product available. VNP46Ax are the only Nighttime Lights (NTL) products available. Please also note that NASA Earth science data are not of a sufficient resolution for viewing small object for example emergency vehicles, individual properties, or similarly-sized features.

Thank you. I was interested in situations such as those emergencies where many vehicles would show up with many lights. A follow up question is whether there are daytime products that could capture such a situation.
