According to scientific papers, the organic carbon content cannot be the values presented in relevant datasets in GEE !?

Maybe the unit should be %, not g/kg (which means 1/1000)! The organic carbon content of peat ranges 18–58% (Agus, Hairiah, et al. 2010) for peatlands, but by implementing these datasets in my...

EBG structures have shown quite good results in improving front to back ratio.

Mahesh Birari

EGB is one of the solution, but as cost effective is metallic reflector plate to avoid/reduce back side radiations.
