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 () of land observation with acceptable errors to determine its mean diurnal blue-sky albedo (). 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.

耕地位置及其粗糙度对土地达到平均日蓝天反照率值的最佳时间的影响


这项工作是文章“影响耕地位置及其粗糙度对蓝天反照率变化的影响”[J Quant Spectrosc Radiat Transf. 296（2023）108,440]。它量化了全球范围内裸露耕地的位置（以纬度表示）及其粗糙度对陆地观测最佳时间（）的影响，并在可接受的误差范围内确定其平均日蓝天反照率（）。文章还讨论了犯这些错误的风险如何随着陆地纬度的变化而变化。该研究的重点是两个半球所有纬度地区共有的一种土壤单元——坎比索尔（Cambisol）的位置的影响。这与上述补充文章中分析的反照率变化是同一单位。
