Item Identification

Title: Concentration of chlorophyll a derived from ocean color remote sensing
Short Name: Chlorophyll (Chlph)
Status: On Going
Creation Date: 2019-04-23
Abstract:

Ocean color remote sensing provide routine, synoptic observations of the ocean surface at spatial and temporal resolutions not attainable by moored or ship-based platforms. Ocean color sensors measure the spectral distribution of reflected sunlight, which can be used to infer the contents of the water, including chlorophyll a concentrations, a proxy for phytoplankton biomass. Phytoplankton are the base of the marine food web and are critical regulators of key biogeochemical processes.
Purpose:

To provide weekly, monthly and annual chlorophyll concentrations of the U.S. East Coast

Data Management

Have Resources for Management of these Data Been Identified?: No
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: No
Approximate Delay Between Data Collection and Dissemination: 90
If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed:

There is an approximate 60-90 delay in the release of the ancillary data needed to generate the science quality data
Actual or Planned Long-Term Data Archive Location: Other
Approximate Delay Between Data Collection and Archiving: None
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

Regular server back-ups, local copies, raw data stored offsite and can be used to recreate files from backed-up programs

Lineage

Lineage Statement:

Level 1 ocean color data are retrieved from NASA's OceanColor Web supported by the Ocean Biology Processing Group. The NASA software SeaDAS is used to generate Level 2 and daily binned files. Statisical data and mapped netcdf files are created using code developed locally in IDL.
