This week features a couple of images taken using different tools available through College of DuPage. Someone once asked me, “why use black and white images when color images are available?”
It just depends on what you are looking for. The top image is in full color, whereas the other two are enhanced black and white images. In this case, there is little difference.
Typically, black and white images give you better contrast and help you see finer details in the cloud structure. This is great for finding mid-day overshooting tops, subtle boundaries and so on that would blend in easier with full-color images.
In the above images, the contrast is good on the color image. This is because the sun is still at relatively low angles (it was still early in the morning), and the features were made larger by shadows. In the middle of the day, those features would wash out, and may only be visible in the black and white image.
Maybe next week, I’ll post a midday example.
Thank you for reading this post!

Don’t know what I’d do without DuPage. The current NWS radar for Chicago is seriously lame.

I like their presentation of models and satellite images, and we use them quite a bit while chasing storms.
