Night-time Lights, 2023 Rolling Fork Tornado

High Definition Black Marble Nightlights (2023 Rolling Fork Tornado)
atmosphere NASA VEDA COG
In plain English

What it measures. A detailed map of how much artificial light glows from the ground around Rolling Fork, Mississippi, after the 2023 tornado. Darker areas mean fewer lights are on, often a sign of power outages or damage.

How it's made. Built from NASA's Black Marble night-time lights, captured by the VIIRS satellite sensor that sees Earth's lights after dark.

How & where you'd use it. Helps responders spot neighborhoods that lost power or were knocked out after the storm.
