Chlorophyll Time Series :   Mean, Median & stdev of the daily composites of the different Ocean Color products (Chlor_a) created routinely for all CoastWatch regions is plotted as a time series.

Not all regions are active as of now. Some of the hi-res regions are for MERIS data from the past (before March 2012). The Chesapeake Bay region uses the tuned regional algorithm which is different from the standard msl12/L2gen used for other MODIS data.

There is also available an Inter-sensor plot where all sensor data for the same region are overlayed on the same plot.

For MERIS a Bias of the time series is available. It uses the bulk statistics for the whole region and plots the difference. (the bias is not calculated on a pixel by pixel basis)

For the granule level data, only a simple time series is provided for individual sensor data. Same is done for the nLw data. Links for those are provided.

The histogram plot shows the most recent data as well as the archived histogram data from the appropriate links.
