**PlanetScope**

Planet Labs’ commercial SmallSat imagery provides high-resolution satellite data crucial for assessing areas heavily damaged by tornadoes. With frequent overpasses, it allows for quick identification of destroyed buildings, vegetation damage, and blocked roads. If skies are clear directly after a tornado strike, first responders can use this data to better serve affected communities. This imagery was also used in this story to analyze reflectance changes in visible bands before and after a tornado, pinpointing areas of intense damage—even down to the building level, thanks to Planet's high spatial resolution.

**NWS Damage Assessment Toolkit**

The NWS Damage Assessment Toolkit (DAT) is a geographic information system (GIS)-hosted dataset where post-storm damage survey results are uploaded and referenced to the location where each description of damage occurred. This dataset includes center lines of all tornado tracks, polygons that break down the EF rating at each point along the path, descriptions of the damage at each entry point, and ground damage pictures of the damage at most entry points.

**WSR-88D and Doppler On Wheels**

The Weather Surveillance Radar (WSR-88D) is a network of radars used by the NWS to monitor weather patterns, including tornadoes, across large areas. In addition, the Doppler on Wheels (DOW) radar, which is mounted on vehicles and can get closer to storms, was examined in cases where it was deployed in order to gather more detailed information. DOW radars are typically used for research and can capture clearer, higher-resolution data on tornadoes, while WSR-88D provides a wider view but with slightly less detail.

**Black Marble Night Lights**

NASA’s Black Marble night lights dataset provides satellite images of Earth at night, capturing the light pollution from cities, roads, and other human activity. These images are collected by the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the Suomi National Polar-orbiting Partnership (NPP) satellite, and can be used to examine changes in illumination over time. In this story, night lights data is used to assess changes before and after a tornado impacts a town, highlighting areas affected by power outages that may cause recovery slowdowns.
