This rectangular image shows the location of satellite-based fire detection targets overlaid on visible imagery of the Los Angeles area landscape. In the center of the image over Pacific Palisades, CA, are nearly 30 pink, light purple, and purple squares showing the location of suspected fires.

Why Do Fires on NASA's Maps Sometimes Look Bigger Than They Really Are?

Satellite-based maps offer quick first alerts and approximate locations of potential wildfires that are then precisely tracked and fought by teams on the ground.

This image shows Hurricane Milton’s storm path between October 5-10, 2024 using Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) Level 1B Brightness Temperature and International Best Track Archive for Climate Stewardship database from NOAA’s National Centers for Environmental Information (NCEI) datasets.

Examining Hurricane Milton's Milestones with NASA's GES DISC Datasets

Join us on January 29 at 2PM ET (-05:00 UTC) to learn how to access and use MERRA-2, GPM, TROPICS, and LDAS data provided by NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) to investigate Hurricane Milton's milestones.
