2013 Special Reports:

Hu and Barnes from the University of South Florida modified the Lee et al. (2005) algorithm to derive 'true' Kd (without bottom effect), or the diffuse light attenuation coefficient, from MODIS data. In situ samples from April 2011 to August 2012 validated the algorithm with an R^2 of 0.68. All data from stations 5 m. or shallower were excluded from this analysis, thus 5 m represents the minimum depth range that this algorithm should be applied. Amplitude (1/2 wave height) of the seasonal cycle was derived from MODIS data for 2002 to 2011 and represents the seasonal variation for all MODIS data for this time period in m^-1.

Purpose:

This dataset was created under the objectives of a NASA ROSES grant to Luke McEachron (co-PI), FWC grant # 2839, titled "Satellite Earth Image Products Applied to Development of Regulatory Water Quality Standards."
