Figures & Tables

Fig. 1

The general Oren and Nayar (1995) model of the diurnal albedo variation.

Fig. 2

The model fitting procedure. (A) Point data generated from Eq. (3); (B) fitting Eq. (4) to points; (C) model correction.

Fig. 3

Scheme of calculation implemented in SALBEC. For symbol explanation, see text. SALBEC, Soil ALBEdo Calculator.

Fig. 5

Visualisation of the results. (A) Location-agnostic soil-surface albedo model produced by the soil surface albedo module (Calcic Xerosol); (B) Diurnal a variation produced by the diurnal albedo module (Calcic Xerosol).

Fig. 6

GUI of SALBEC: (A) main window – results of the calculations; (B1) ribbon – soil section; (B2) geo-location; (B3) days of the analysis; (C1) spectra manager and (C2) collection manager. GUI, graphic user interface; SALBEC, Soil ALBEdo Calculator.

Fig. 7

Laboratory reflectance spectra of Haplic Xerosol and Calcic Xerosol used in the example.
