Web30. okt 2024 · The Light Reflectance Value (LRV) can be obtained using the CIE Y values measured under the illuminant D65 (natural daylight) and 10° observer . This measurement can be conducted easily using a sphere-based spectrophotometer like Spectrophotometer CM-25d that has a calibration certificate that is traceable to international standards. WebIce and snow generally show a high degree of reflection at visible wavelengths (VIS; ca 0,4 – 0,75 µm), lower reflection in the NIR (Near InfraRed, wavelength ca 0,78 - 0,90 µm) and very low reflection in the SWIR (ShortWave InfraRed, wavelength ca 1,57 - 1,78 µm). The low reflection of ice and snow in the SWIR is related to their ...
