One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure.

误差的一个来源是折射，即光束通过不同温度和压力的空气层时发生的弯曲现象。

We develop a statistical framework that uses lights growth to augment existing income growth measures, under the assumption that measurement error in using observed light as an indicator of income is uncorrelated with measurement error in national income accounts.
