radiance temperature
1.Measurement precision of the specific radiance and the temperature are discussed. To polishing steel cast at 427℃, the results are NETD≤0 32K ,σ ε λ =6 5×10 -3 ,|σ ε λ /ε λ |=1 20%;
2.This radiator has, for any wavelength and any direction, the maximum spectral concentration of radiance at a given temperature.
3.A light/heat conversion absorption coating, based on acrylic modified silicone as binder and FeMnCuO 4 semiconductive compound oxide as pigment, has been developed, with the ratio of absorptance/radiance(a s/ε n) up to 1 80 The influences of P/B ratio, substrates, film thickness, particle size and temperature on the optical properties of coating were discussed
4.The AIRS cloud-cleared radiance spectrum is spectrally reduced to mimic all MODISinfrared spectral bands within the AIRS spectral range. These aggregated measurements, MODIS-like in spectral coverage but at the spatial resolution of AIRS, are expressed as brightness temperatures and are compared with MODIS clear sky brightness temperature observations within all successfully cloud-cleared AIRS footprints.
