Eelis Halme, Matti Mõttus. (2023). Improved parametrisation of a physically-based forest reflectance model for retrieval of boreal forest structural properties. Silva Fennica vol. 57 no. 2 article id 22028. https://doi.org/10.14214/sf.22028
Keywords: forest structure; Sentinel-2; reflectance; hyperspectral; tree distribution
Highlights: Spatial distribution of trees is a key driver for forest reflectance; Knowledge of the ratio of branch to leaf area improves forest reflectance simulation substantially; Different optical properties of the two leaf sides have a notable effect on forest reflectance.

Aarne Hovi, Matti Mõttus, Jussi Juola, Farshid Manoocheri, Erkki Ikonen, Miina Rautiainen. (2020). Evaluating the performance of a double integrating sphere in measurement of reflectance, transmittance, and albedo of coniferous needles. Silva Fennica vol. 54 no. 2 article id 10270. https://doi.org/10.14214/sf.10270
Keywords: vegetation; albedo; reflectance; transmittance; needle carrier; spectra
Highlights: Adaptation of a compact double integrating sphere for spectral measurements of coniferous needles; Double integrating sphere is fast to operate and suitable for monitoring purposes and collection of large spectral databases; Measured spectra showed negative bias, which could potentially be reduced by building an optimized measurement setup.
