SeaWifs aerosol and chlorophyll

Analyses of 5-day mean chlorophyll anomalies for the northeast Pacific coastal regions from the Queen Charlotte Islands to Baja California.

Rotated principal component analysis was applied to SeaWiFS chlorophyll anomaly data for 1997-2010, and six regions were identified as having coherent cholorphyll variability. Lag composites of chlorophyll, SST, winds and wind stress, and sea-level pressure are provided below. The times in the PDF files are days with respect to the peak maximum chlorophyll for each region.

The data is written as a 9-column ASCII file. The columns are:
1) year
2) month
3) day of month
4) chlorophyll for the Vancouver Island pattern (GIF| PS)
5) Southern Washington - Northern Oregon pattern (GIF| PS)
6) Heceta Bank pattern (GIF| PS)
7) Southern Oregon - Northern California pattern (GIF| PS)
8) Gulf of the Farallones pattern (GIF| PS)
9) California Bight - Gulf of Magdalena pattern (GIF| PS)

The time series are the amplitude of each pattern for the 0.5-degree regions that are correlated with the pattern time series at at least 0.3.

The aerosol and chlorophyll signals are cross-contaminated in SeaWiFS, and the tendency filter removes the cross-contaminated part. Each grid box is 2.5-degrees latitude-longitude.
