The average daily soil moisture across the globe


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at the average daily soil moisture across the world.

The darker blue and purple areas reflect a high soil moisture, which would be found in places like the northeastern United States. The brown and orange areas reflect low soil moisture, such as a desert. The green areas are rainforests, while the white areas are frozen soil.

The clip was compiled using 40 years of research data from a range of satellite sensors. While soil moisture information is essential for a wide range of hydrologic and climate applications, spatially-continuous soil moisture data is only available from satellite observations or model simulations.

Here we present a global, long-term dataset of soil moisture derived through machine learning trained with in-situ measurements, Surface soil moisture is the water that is in the upper 10 cm of soil, whereas root zone soil moisture is the water that is available to plants  Northeast China ( Dongbei ) is historically known as “Manchuria”. It now mainly encompasses China’s three northmost provinces – Liaoning, Jilin and Heilongjiang, economically and politically among the most important regions of China.
