Dataset Overview

Provides daily average estimates of a wide range of physical properties of the water column for Lake Kasumigaura based on manual sonde lake data and daily average weather data, for 1977-2015. Manual sonde data typically consisted of a single water column profile collected at weekly or bi-weekly intervals and the sonde data were matched with the corresponding daily average weather data and then used as input into rLakeAnalyzer() package in R v3.6.0 (Read et al. 2011). The daily average weather data are included. Quantiles of each variable (i.e., the ranked order as a proportion) are provided to facilitate evaluation of extreme observations.
