Using MODIS Dust product to see the strongest dust outbreak in Miami for the month of July

The Terra MODIS Dust product below shows a Saharan Dust plume just southeast of Florida on July 24th at 1551UTC.  This is shown by the magenta and pink colors inside the white oval outline. The top right graph displays the average daily Aerosol Optical Depth (AOD) for the six Saharan Dust events that were experienced in Miami in the month of July of 2012.  The strongest one was observed on July 24th with a daily average AOD of 0.50.  The graph on the bottom right displays the hourly AOD for July 25th (day after) with a daily average AOD of 0.435 at 500 nm.  AODs due to dust less than approximately 0.25 to 0.30 were difficult to discern in the Terra MODIS Dust product, not showing a clearly defined magenta or pink color.  This dust plume extended from the surface to about 4.5 km with the highest concentrations between 2.5 and 3.0 km as measured from LIDAR.

  1. Nice post! While SPoRT is currently NOT providing the NASA AOD product from MODIS, have you looked at it off-line (from other sources) to see how well it tracks/ relates to your ground-based observations?
