Does "take in" here mean see or watch?

Context:

Shelley also mentions that when the West Wind blows, it seems to be singing a funeral song about the year coming to an end and that the sky covered with a dome of clouds looks like a 'sepulchre' i.e. a burial chamber or grave for the dying year or the year which is coming to an end.
Shelley in this canto “expands his vision from the earthly scene with the leaves before him to take in the vaster commotion of the skies”. This means that the wind is now no longer at the horizon and therefore far away, but he is exactly above us. The clouds now reflect the image of the swirling leaves; this is a parallelism that gives evidence that we lifted “our attention from the finite world into the macrocosm”. The ‘clouds’ can also be compared with the leaves; but the clouds are more unstable and bigger than the leaves and they can be seen as messengers of rain and lightning as it was mentioned above.
