If you want to understand how climate works, you need to ask: What is the state of the climate? How do you observe it? How do you create budgets from it? The book explains why you need these three aspects as a foundation for understanding climate. The authors present the established budget law in a new light: the storage, outflow, and transformation of each individual state variable, such as energy, sum to zero. The book's focus is on how to optimally use this formula along with measurements, for example from satellites, and modern estimation methods to create a consistent picture of the Earth's climate. This results in a global budget climatology based on re-analyzed data from 1979 to 2013, complete with trends, flows, and transformation rates. It shows, among other things, that the climatic flow equilibrium is currently disturbed, particularly evident in...
