Short summary
We present a global dataset that follows the movement of air carrying water and heat through the atmosphere from 1979 to 2024. Using weather reanalysis data, we tracked millions of air parcels and recorded their physical properties as they moved through the atmosphere. The dataset can be used to reveal where rainfall and warming originate and how they travel across land and ocean. This dataset can support climate and water studies without the need for costly simulations.
