Defining the Landsat TM/ETM+ and CHRIS/PROBA spectral regions in which turbidity can be retrieved in inland waterbodies using field spectroscopy
This article describes the results obtained by an existing campaign in which in situ
spectroradiometric measurements using a GER1500 field spectroradiometer, Secchi
disk depth, and turbidity measurements (using a portable turbidity meter) were
acquired at Asprokremmos Reservoir in Paphos District, Cyprus. Field spectroradiometric
and water quality data span 18 sampling campaigns during the period May
2010–October 2010. By applying several regression analyses between ‘In-Band’ mean
reflectance values against turbidity values for all spectral bands corresponding to
Landsat TM/ETM+ (Bands 1 to 4) and CHRIS/PROBA (Bands A1 to A62), the
highest correlation was found for Landsat TM/ETM+ Band 3 (R2 = 0.85) and for
CHRIS/PROBA Bands A30 to A32 (R2 = 0.90)
