Title: Coastal Zone Color Scanner (CZCS) Level 2 Products
Description:
Abstract:
The purpose of the CZCS on Nimbus-7 was to obtain a better understanding of the temporal and spatial distribution of phytoplankton biomass and primary production, and a better understanding of the processes regulating the growth of phytoplankton and of the processes influencing the ultimate fate of this organically fixed carbon. Satellite observations of ocean color were necessary to provide reliable estimates of marine phytoplankton biomass on synoptic scales which are useful in studies of phytoplankton processes. The mission objectives for the CZCS were to obtain observations of ocean color and temperature, particularly in the coastal zones, which would provide data with sufficient spatial and spectral resolution for the following applications: - Measure concentrations of chlorophyll-a and phaeophytin. - Map biologically productive areas. - Map suspended sediment distribution and determine the type of materials suspended in the water. - Map Gelbstoffe (yellow substances) as an indicator of salinity. - Detect pollutants in the upper level of the oceans. - Map temperature of coastal waters and the open ocean. - Study the interactions between coastal effluents and open waters. Level 2 Data contain 6 derived geophysical parameters for each CZCS scene: - Phytoplankton Pigment Concentrations - Diffuse Attenuation Coefficient - Normalized Water-Leaving Radiance @ 440 nm - Normalized Water-Leaving Radiance @ 520 nm - Normalized Water-Leaving Radiance @ 550 nm - Aerosol Radiance @ 670 nm Each data segment is a single CZCS scene with a maximum of 2 minutes of data. Approximately 66,000 2-minute individual scenes were collected. The level 2 scenes are partial orbital swaths. In one two-minute data segment, the CZCS covers approximately 1.3 million square kilometers of the ocean surface. Level 2 derived geophysical parameters have a spatial resolution of about 4 km at nadir. DATA MEDIA AND FORMATS: The ESA/EPO NIMBUS-7 CZCS Level 2 products are recordered on Computer Compatible Tape (CCTs) in a format that is "partially" conformed to the Standard Family Format (SFF) convention. Conventionally, the individual tape is referred to as a physical volume. The logical volume refers to data files logically grouped on the tape. The SEF allows that more than one logical volume (a volume set) be stored on the same physical volume. One logical volume can also be split between different physical volumes. The logical volume of ESA/EPO CZCS Level 2 product consists of the following files: - A volume directory file which contains the logical and physical structure of the tape (the number of all files on CCT: the position and content of these files; the number of records and maximum record length within each files) - The data files: the imagery files are preceded by a quicklook file & leader file and followed by a trailer file (the quicklook file contains quicklook image and catalogue information; the leader file contains scene introductory information; the trailer file contains quality flags as determined during the scene processing) - A null volume directory file which indicates the end of the logical volume of a volume set (a collection of logical volumes).
