Source Contribution: |
Monthly chlorophyll geotifs previously created (by Varis Ransi) were used to make grand monthly means, which consist of all of the months for the time series averaged together to make one mean image(ex: Jan '98, Jan '99, Jan 00, Jan 01, Jan 02, Jan 03, Jan 04 = SW1998200401_AVGCHL_UTM.tif). | Source Geospatial Form: unregistered | Type of Source Media: geotifs |
Process Steps
Process Step 1
Description: |
An EASI program was run on the previously created grand monthly chlorophyll geotifs of the SeaWiFS northeast region to create geotifs for the specified region of the Gulf of Maine. The new geotifs were also reprojected from their original SIN E019 projection to Albers Conical Equal Area, GCS NAD 83. These images are scaled down from 16 bit data to 8 bit data. In order to get the chlorophyll values from the 8 bit geotifs the following formula should be applied to the 8 bit data values: CHL = 10^(((8bit # -1)*(3/250))-1.3) |
