Where you should start here depends on what you already know; we've adopted a back-to-basics approach to try and help everyone understand the science of COSMOS-UK. Jump into part 4 if you just want to know how the cosmic-ray soil moiture sensor works and how this compares to other measurement technologies. Or go straight into part 5 to understand the research challenges and opportunites of the COSMOS-UK project.

  1. What is soil?
  2. What is soil moisture?
  3. Why measure soil moisture?  
  4. How do we measure soil moisture?
  5. Research activity.
