پایگاه داده باز چرخه آب زمین را با استانداردسازی چندین دهه داده های ماهواره ای ردیابی می کند

Open database tracks Earth's water cycle by standardizing decades of satellite data

All water comes from somewhere. Researchers who want to know where it comes from rely on water isotopes, variants of water molecules with slightly different masses, as location identifiers. In particular, the specific ratio of heavy to light water isotopes is unique to the water's origin and processes it has undergone and can provide information on how water travels across the globe.
