Monthly turbidity geotifs created from SeaWiFS imagery

CC ID: 600648
Contact Name: NOAA, NOS, CCMA
Publish Date: 2005-01-01
Extent Type: Range
Extent Start Date/Time: 1997-09
Extent End Date/Time: 2005-06
Source Contribution:

The source geotifs were used to create geotifs in the Albers Conical Equal Area projection and the geographic coordinate system name of GCS North American 1983. The horizontal datum name is North American Datum 1983 with an ellipsoid of Geodetic Reference System 80 | Source Geospatial Form: unregistered | Type of Source Media: geotifs

Process Steps

Process Step 1

CC ID: 600649
Description:

An EASI program was run on the MOnthly turbidity geotifs of the SeaWiFS northeast region to create Seasonal Average geotifs for the specified region of the Gulf of Maine. These images were created using the following months: Winter= December, January, February Fall= September, October, November Spring= March, April, May Summer= June, July, August. These seasonal average turbidity geotifs were used to make grand seasonal Mean images, which consistof the average of all Mean images for each season in the time series.(ex: spring '98, spring '99, spring 00, spring 01, spring 02, spring 03, spring 04 = SW1998200401_GrdSSN_Avg670.tif). The new geotifs were reprojected from their original SIN E019 projection to Albers Conic Equal Area,NAD 83, GRS 80. These images are scaled down from 16 bit data to 8 bit data. In order to get the turbidity values from the 8 bit geotifs, the following formula should be appliedto the 8 bit data values:Turbidity = 10^(((8bit# - 1)*(3/250))-4.0)
