The influence of the location of arable land incorporating its roughness on the optimal time when the land reaches its mean diurnal blue-sky albedo value

Abstract

This work is a supplement the article “Influence of arable land location incorporating its roughness on blue-sky albedo variation” [J Quant Spectrosc Radiat Transf. 296 (2023) 108,440]. It quantifies the influence of the location (expressed by latitude) of bare arable land on a global scale and its roughness on the optimal time (To) of land observation with acceptable errors to determine its mean diurnal blue-sky albedo (αd). The article also discusses how the risk of making these errors changes with the change in land latitude. The study focuses on the influence of the location of one soil unit, Cambisol, common to all latitudes in both hemispheres. This is the same unit whose albedo variation was analyzed in the supplementary article mentioned above.
