Fig. 7: Validation of the satellite-derived total suspended solids concentration (TSS) and chlorophyll-a concentration (Chl-a) versus in situ observations collected from the water near the Odesa coast after the dam breach.
From: The biogeochemical response of the north-western Black Sea to the Kakhovka Dam breach
a Comparison between satellite-derived TSS and in situ TSS measured on the same day as the satellite overpass. b Comparison between satellite-derived TSS timeseries and in situ measured TSS timeseries. c Comparison between satellite-derived Chl-a and in situ Chl-a measured on the same day as the satellite overpass. d Comparison between satellite-derived Chl-a timeseries and in situ measured Chl-a timeseries. The vertical solid line in a and c indicates the standard deviation of values within the 3 × 3-pixel window from the satellite image. The regression analysis, root mean square error (RMSE), median absolute percentage error (MAPE) and bias for plots a and c were calculated using untransformed values.
