In the following image (from this article)
they claim the orange part is the troposphere, the yellow/almost white part is the stratosphere and the light blue part obviously the mesosphere while those above would be the mesopause and the thermosphere.
I'm pretty sure they got it wrong.
- What is considered the "stratosphere" is far too small to be the stratosphere, even if excluding the isothermal layer.
- The alleged stratosphere has clouds in it, hence it can't be it nor even the isothermal layer alone. The "stratosphere" in the image is still part of the very troposphere and the difference in colors seems to be due to the different cloud layers only. In fact you can see to the very right that there's little difference between the alleged "stratosphere" and the troposphere; it seems to be one and the same layer.
- I guess that in fact the layer(s) called "troposphere" and "stratosphere" are both the troposphere (up to ~12 km (7.5 mi)), the light blue layer is the isothermal stratosphere layer (12-20 km (12.5 mi)) and the very dark blue layer above is the rest of the stratosphere (above 20 km to above 25 km (15.5 mi) depending on the latitude).
What are your thoughts on this and how do the layers compare to those in the images in my other question where they're imaged in broad daylight, not during sunset?
