This is a specific use of phenology, studying animal/plant life cycle events, like flowering time.
Since ancient times, people have noticed these events – the first snowdrops show spring, for example – and in the 19th century, some naturalist-nerds started recording the exact dates. This was then a surprise climate change dataset.
Thanks for sharing! I've been following a bunch of car enthusiasts from Japan on Instagram, and the past week or so they've begun posting photos of the cherry blossoms. Very cool to visualize the actual progression with a map (since I don't know many of the mentioned areas in the posts, usually).
