Noise-Equivalent-Spectral-Radiance

Limb spectral calculations RFM-OFM limb radiance calculations agree to within a fraction of the MEPAS specified Noise Equivalent Spectral Radiance (NESR). [Pg.343]

We call the signal for which the signal-to-noise ratio is unity the Noise-Equivalent-Spectral-Radiance,... [Pg.232]

Repeated measurements of the responsivity also reveal random errors in the system. These errors are expressed foreach resolved spectral interval by the standard deviation, s r v)). The relative error is then s(r(v))/r v). The Noise-Equivalent-Spectral-Radiance, NESR, is defined by... [Pg.290]

A choice of instrumentation always involves trade-off considerations between signal-to-noise ratio, spectral and spatial resolution, telescope aperture, detector characteristics, frequency response, bit rate, and many other parameters. Clearly, the overall scientific objective should dictate the instrumental approach, but, in reality, the chosen solution must also fit within the framework of available resources such as volume, weight, power consumption, time required to complete the design, and cost. Within reason, these limitations are generally also subject to trade-off considerations. To limit ourselves in the presence of a multitude of instrumental approaches consider the Noise-Equivalent-Spectral-Radiance, NESR, of a radio-metric instrument, Eq. (5.8.14),... [Pg.296]
