As chlorophyll absorbs light to convert it to energy, it emits a bit of fluorescent light. Â Using existing satellites NASA figured out how to measure this florescence.
Below, you see North America during growing season…wherein it demonstrates that during this time of year it is the most productive (in terms of amount of photosynthesis) area on the planet. Â _This includes being more active than the Amazon basin_.

Wow. Yo have a link to that?

My eyes itch just looking at that
Any reason not to include the link in the OP?
Normally, I paste a link and it makes the fancy link attached to the post.
I wanted to feature the picture, so I uploaded the picture and then just forgot to include the link and I haven't been at the computer to edit the post since I put it in the comment above.
So, the reason is forgetfulness at the beginning and not wanting to edit on my phone.
Fascinating – thanks for posting that.Â
