Metadata: Monthly average non-algal Suspended Particulate Matter concentrations on the UK shelf waters
Abstract:
Spatially gridded, monthly average of non-algal Suspended Particulate Matter (SPM). Based on satellite derived Ifremer OC5 algorithm (Gohin et al 2011). Interpolated and merged data from SeaWiFS, MODIS, MERIS and VIIRS satellite sensors.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

Internal code | Internally assigned metadata identifier | 9325 |
Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Monthly average non-algal Suspended Particulate Matter concentrations on the UK shelf waters |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | DBEIS, Department of Business, Energy & Industrial Strategy |
File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS15247b97-45a4-4bf9-83ab-390788cfc397 |
Resource Identifier | This is the code assigned by the data owner. | CEFAS18133 |
Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1998-01-01 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2015-12-31 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 1100 |
Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | asNeeded |
Abstract | The abstract provides a clear and brief statement of the content of the resource. | Spatially gridded, monthly average of non-algal Suspended Particulate Matter (SPM). Based on satellite derived Ifremer OC5 algorithm (Gohin et al 2011). Interpolated and merged data from SeaWiFS, MODIS, MERIS and VIIRS satellite sensors. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Based on Gohin et al (2005) OC5 algorithm that jointly estimates the load of Chlorophyll and non-algal suspended particulate matter. This algorithm has been validated against in-situ coastal observations for the English Channel and Bay of Biscay (Gohin, 2011) and modified to merge multiple sensors (Saulquin et al. 2011): SeaWiFS from 1998-2002; MODIS + MERIS, January 2003-March 2012 and MODIS + VIIRS from April 2012 to the present. The daily products generated from multiple sensors and interpolated to 1.1 km were extracted from ifremer’s ftp site: `ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/ocean-color/atlantic/EUR-L4-SPIM-ATL-v01/`_ . The data extends from 13°W to 12°E and 36°N to 60°N. This covers the continental shelf in UK waters to the exception of the Faroe-Shetland channel North of 60°N). The daily images of non-algal SPM from 1/1/1998 to 31/12/2015 were averaged into 12 monthly means for the 18 years (216 fields). These were used to calculate a climatological average (Figure 7) as well as a climatological monthly averages (see Appendix A). The yearly anomaly was calculated as the difference between the yearly average and the climatological mean (see Appendix B). The several satellites have been cross calibrated but caution should be used when comparing average values from SeaWiFS (1998-2002) with more modern sensors (Gohin, pers. comm.). .. _`ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/ocean-color/atlantic/eur-l4-spim-atl-v01/`: ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/ocean-color/atlantic/EUR-L4-SPIM-ATL-v01/ |
