ESSIC / CICS-MD Senior Faculty Specialist Ron Vogel recently co-authored a paper in Remote Sensing Letters titled “Approximation of diffuse attenuation, Kd, for MODIS high-resolution bands”.
The paper discusses Kd-hires, a high resolution depth attenuation product used as a measure of water clarity. The authors compare the product with Wang’s operational Kd, another method of measurement, and found that the two algorithms had good agreement, ensuring improved retrievals. The product’s high resolution is anticipated to expand usage of satellite water clarity measurements for small-scale coastal research and monitoring, such as aircraft monitoring of submerged vegetation and laser bathymetric mapping of coastal tributaries and creeks.
In his research, Vogel applies earth-observation satellite data to environmental decision-making. He currently develops decision-support tools for water quality, fisheries and climate change in coastal areas. Other interests include ecological modeling with satellite data and vegetation and land surface monitoring by satellite. He has expertise in both visible and infrared satellite remote sensing.
