Abstract

The authors present bio-optical data spanning 316 sets of observations made at 34 inland waterbodies in Australia. The data was collected over the period 2013-2021 and comprise radiometric measurements of remote sensing reflectance (Rrs), diffuse attenuation extinction coefficient (Kd); optical backscattering; absorption of coloured dissolved organic matter (aCDOM), phytoplankton (aph) and non-algal particles (aNAP); HPLC analysis of algal pigments including chlorophyll-a (CHL-a); organic and inorganic total suspended solids (TSS); and total and dissolved organic carbon concentration. Data collection has been timed to coincide with either Landsat 8 or Sentinel-2 overpasses. The dataset covers a diverse range of optical water types and is suitable for algorithm development, satellite calibration and validation as well as machine learning applications.

摘要

作者展示了在澳大利亚34个内陆水体进行的316组观测的生物光学数据。这些数据是在2013年至2021年期间收集的，包括遥感反射率（Rrs）、漫衰减消光系数（Kd）的辐射测量；光学后向散射；有色溶解有机物（aCDOM）、浮游植物（aph）和非藻类颗粒（aNAP）的吸收；藻类色素（包括叶绿素-a（CHL-a））的HPLC分析；有机和无机总悬浮固体（TSS）；以及总有机碳和溶解有机碳浓度。数据收集时间与陆地卫星8号或哨兵2号的过境时间一致。该数据集涵盖了多种光学水类型，适用于算法开发、卫星校准与验证以及机器学习应用。
