Satellite Image of the Week: #27

**I was having all sorts of connectivity issues yesterday. This was actually supposed to be posted yesterday, but it is late.**

I am in Seattle this week, and so I thought I would show a few images to explain distortion in satellite images.

The GOES satellites are geostationary (hence the “G” in GOES). This means they rotate with the earth, hovering over the same spot as the earth turns. The land directly under the satellite is the least distorted in the satellite imagery.

The satellite image takes a round thing and squishes it into a flat image. Just like squishing an orange flat, the center of the image remains less distorted, and the edges become stretched and distorted to flatten the image.

Here, we have an image of the Pacific Northwest using the a GOES East satellite. Notice how Washington state is distorted, and that this image would be hard to use for weather predictions.

Now, look at the image of the Pacific Northwest using a GOES West satellite. The distortion is limited, and we can use this image to predict the weather.

Thank you for reading this post!
