Acronyms

A product format used by OSI SAF

A time series of measurements of sufficient length, consistency, and continuity to determine climate variability and change.

OSI SAF GMF ?

Copernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European system for monitoring the Earth. Copernicus consists of a complex set of systems which collect data from multiple sources: earth observation satellites and in situ sensors. It processes these data and provides users with reliable and up-to-date information through a set of services related to environmental and security issues. The services address six thematic areas: land, marine, atmosphere, climate change, emergency management and security. The marine service uses OSI SAF products as inputs.

US Air force DMSP satellites (DMSP-F19 with instrument SSMIS on board for example) are used in OSI SAF Sea Ice processing

The Equal-Area Scalable Earth Grid (EASE-Grid) is intended to be a versatile format for global-scale gridded data, specifically remotely sensed data.
This Lambert azimuthal equal-area is used for OSI SAF sea ice products.

The EUMETSAT Data Centre provides a long-term archive of data and generated products from EUMETSAT, which can be ordered online.

ESA is responsible for several satellites of interest, in particular ENVISAT satellite, from which is derived the AATSR SST, key reference for the OSI SAF, and for the SENTINEL-3 satellite.

Technical specification of GHRSST products and services

The GHRSST gathers an international community of users involved in scientific projects and operational Oceanography, and as a consequence is an important source of requirements for the OSI SAF. More information in the GHRSST User Guide version 9 (ftp://podaac.jpl.nasa.gov/allData/ghrsst/docs/GHRSSTUserGuidev9.pdf)

Levels from 0 to 4 have been defined by the remote sensing community to describe the processing level of products. Level 0 represents raw data, while Level 4 data have had the greatest amount of processing applied.
Level 1B are unprocessed instrument data alongside ancillary information (Level 1A data) that have been processed to sensor units.

On top of levels from L0 to L4 defined by the remote sensing community to describe the processing level of products, the SST community has developed a set of SST definitions in the context of the GHRSST.
L2P products are satellite SST observations together with a measure of uncertainty for each observation in a common GHRSST netCDF format.
Auxiliary fields are also provided for each pixel as dynamic flags to filter and help interpret the SST data.

Levels from 0 to 4 have been defined by the remote sensing community to describe the processing level of products. Level 0 represents raw data, while Level 4 data have had the greatest amount of processing applied.
Level 3 products are data which have been spatially and/or temporally re-sampled (i.e., derived from level 1 or 2 products). Such re-sampling may include averaging and compositing.
The OSI SAF products are L2 and L3 products based on lower level products mainly provided by EUMETSAT.

L3P was never formally defined in a GHRSST Data Specification, but some people still use the term informally.
See L2P and L3C definitions.

Mercator Ocean is a privately-owned non-profit company. It provides operational real-time ocean analyses and forecasts. The organisation was founded and is funded by the five major French institutions involved in operational oceanography: CNRS, Ifremer, IRD, Météo-France and SHOM.
Mercator Ocean is the CMEMS (Copernicus Marine Service) delegate of the European Union.

Satellite Application Facility on support to NoWCasting and very short range forecasting

OSCAR is a resource developed by WMO in support of Earth Observation applications, studies and global coordination.
It contains quantitative user-defined requirements for observation of physical variables in application areas of WMO (i.e. related to weather, water and climate). OSCAR also provides detailed information on all earth observation satellites and instruments, and expert analyses of space-based capabilities.

Satellite Application Facility on Ocean and Sea Ice

The OSTIA system produces a daily high resolution analysis of the sea surface temperature (SST) for the global ocean.
