This particular learning path will seek to give you insight of the following elements: scales of processes and observations, Earth system processes, data integration, observation models, process model, observables as well as the working together of process model and observation model. Note that some of these elements are already captured and explained under the topic "Introduction to Data Integration"and may not be elaborated here, anymore.
This path commences with scales of processes and observation as explained under the topic: "Introduction to Data Integration".
The subsequent element in this learning path for our consideration is the concept of the spheres to include atmosphere, hydrosphere, biosphere etc.
In this learning path, it is essential to talk about the concept of Earth system process as rationalized earlier in the learning path 3.15 - Introduction to Data Integration.
We will also look at Data Integration as a concept in this path in order to understand why such process.
This leads us to observation model as an element worth of looking at as an element of this learning path.
Besides observation model, we also need to know process model as an element in this learning path as stressed earlier in learning path 3.15 -- Introduction to Data Integration.
In this learning path, we will also have a look at the concept of observable, in order to understand the variables of Earth Observation.
Last but not least concept for our discussion under this learning path is the concept of Radiative Transfer model, which describes the relations between physical and biochemical properties of objects.
