The phrase "above ground processes" is correct and usable in written English.
It can be used in contexts discussing environmental science, construction, or any field where processes occurring above the earth's surface are relevant.
Example: "The study focused on above ground processes that affect soil erosion and water runoff in urban areas."
Alternatives: "surface processes" or "aerial processes".
However, little is known on below- and above-ground processes leading to these positive effects.
Moreover, models should target the entire soil plant atmosphere system, including often neglected above-ground processes such as pesticide volatilization, interception, sorption to plant residues, root uptake, and losses by runoff.
Recent peatland restoration studies have highlighted the need to modify the conventional approach of monitoring the recovery of biogeochemical functions through above-ground processes by integrating below-ground components, which are potentially sensitive indicators of reclamation trajectory in long-term monitoring programs.
It is important to point out that flux rates measured in this experiment reflected the combination of above-ground processes driven by eelgrass and algae as well as sediment processes.
"My own thoughts are that we probably should bring the stuff up above ground and process it into a less toxic form of arsenic and put it at the bottom of the mine," says Kevin.
Soil C measurements are important because the underground processes driving soil respiration form a large component of ecosystem gas exchanges, but these are less well-understood and measured compared to above ground stocks and processes (Ehman et al. 2002).
Overall, our data suggest that both above ground and sediment processes contributed to fluxes of inorganic nutrients and that DIN and PO4−3 were regenerated in ratios consistent with Redfield organic matter (Fig. 6).
This method involves extracting contaminated groundwater via wells or trenches and treating the groundwater above ground (ex situ) using processes such as air stripping, carbon adsorption, biological reactors, or chemical precipitation (U.S. EPA 2001).
Above-ground retorting processes tended to yield a lower API gravity shale oil than the in situ processes.
Unfortunately this would likely turn out to be a mistake, as history shows the Brotherhood is easier to deal with when it is above ground and involved in the political process, rather than below ground cultivating links to more radical groups.
Once it has reached the surface, a portion of them form a stalk above ground, by turning their bodies into hard cellulose – a process that kills them.
