The phrase "at a macroscopic level" is correct and usable in written English.
It can be used when discussing phenomena or observations that are visible to the naked eye or when considering large-scale aspects of a subject.
Example: "When examining the ecosystem, we must consider the interactions between species at a macroscopic level to understand the overall health of the environment."
Alternatives: "on a large scale" or "from a broad perspective".
We consider the problem of modeling traffic phenomena at a macroscopic level.
This meant, says Olivetti, "understanding how the atomistic behavior of materials translates to properties at a macroscopic level". She created compounds in the laboratory, and studied manufacturing processes at scale.
We review the observed effects at a macroscopic level in terms of creep deformation, creep rupture times and crack growth rates from a number of sources and a range of materials.
Consequently, the combination of self-assembly and patterning allows for the controlled fabrication of the novel magnetic nanostructures at a macroscopic level and the study of fundamental aspects in magnetism such as quantum tunneling magnetization and magneto-transport properties along well-defined nanosized patterns.
The pores were studied at a microscopic level, the interconnected pore system at a macroscopic level and the results obtained were compared with the measurement of the corresponding ion transport of Cl− and Na+ through the pore system to contribute to an overall understanding of ion transport in porous materials.
Multiple tumor nodules can be appreciated already at a macroscopic level in all liver lobes.
Air slipping along the fuselage moves slower, so the engines ingest less oxygen and burn less fuel.Making planes more slipperyChanging the shape of an aircraft can be done at a microscopic as well as a macroscopic level.
Remarkably, this is not the case for α3β4 receptors, at least at macroscopic level.
And with mass nouns like furniture or silverware, the problem appears even more clearly, at the macroscopic level: a table is furniture, a leg of the table is part of the table, but the leg isn't furniture.
The fundamental idea is that at the macroscopic level a mathematical description of a certain process merely requires the incorporation of those other processes that exert some influence on the considered one.
However, a systematic study investigating the effects of US on the increase in tissue permeability and, therefore, increased distribution of drugs in the brain at a macroscopic tissue-level has not been performed.
