Estimating the irradiance spectrum from measurements in a limited number of spectral bands

open access: yes, 2006
Accurate measurement and characterisation of fluctuations in the irradiance environment is important for many areas of optical remote sensing. This paper describes a method of estimating spectral irradiance over the region 400 – 1000 nm from the radiance
