## What you would see

The image is a satellite view of the Gulf of Mexico and the Caribbean, overlaid diagonally by a broad, tilted data band running from the upper left to the lower right. Outside that band, the ocean is almost black and the land appears in natural tones of green and brown: Mexico occupies the left and bottom edges, the Yucatán Peninsula points upward at center, Florida appears in the upper right corner, and Cuba stretches in from the right edge. Small white labels read 'Mexico,' 'Florida,' and 'Cuba.' Inside the tilted band, deep saturated blue covers much of the Gulf, bordered by irregular white veils that indicate clouds. Over the Yucatán, a flat, bright green fills the land shape. To the right, white, mottled cloud masses and green areas of rain surround the most striking detail: just south of Cuba, a compact, concentric swirl of green, yellow, orange, red, and black rings with a small dark center — the core of Hurricane Ian, where air and water vapor moved fastest. Another smaller red-and-yellow patch glows farther south, near Central America, amid green and white. The overlay has crisp, cut-out edges, like a strip of colored tracing paper laid over a map.

## How to look at it

First follow the tilted band from the upper left to the lower right: that is the instruments' path, not the shape of the storm. Then find the small concentric eye beside Cuba and compare it with the broad white and green areas around it. The most intense colors are compact; the affected area is much larger.

## Context

According to NASA/JPL-Caltech, this image combines microwave measurements from COWVR and TEMPEST, two instruments built at NASA's Jet Propulsion Laboratory to provide weather data over the open ocean. From the International Space Station, they observed Hurricane Ian on September 27, 2022, as it approached Cuba on its way toward the U.S. mainland. Ian made landfall in Cuba's Pinar del Río province as a Category 3 hurricane, with estimated winds of 125 mph (205 kph). The data were sent via NASA's TDRS satellites, processed at JPL, and made available to forecasters in under two hours.

## Curious detail

COWVR, one of the two instruments that produced this image, is about the size of a minifridge, yet it measured ocean winds from low-Earth orbit aboard the International Space Station.

## Questions

- What changes when a hurricane is shown as colored data instead of a photograph of clouds?
- How does knowing this image reached forecasters in under two hours affect the way you look at it?
- What do the areas outside the tilted band — where no data were collected — leave unknown?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. Inside the data swath, which territory appears completely filled with a flat bright green?
2. What color is the outermost ring of Hurricane Ian’s compact core south of Cuba?
3. How many white place names can you read on the dark map outside the swath?
