In order to document OSI-SAF's impact and enable ongoing support of OSI-SAF, you are obligated to acknowledge OSI-SAF in your work.
Therefore, an acknowledgment similar to the following should be included in your publication:
“We acknowledge the Ocean and Sea Ice Satellite Application Facility (OSI SAF) High Latitude Processing Center for producing and making available their reprocessing data sets and derived products from the Danish Meteorological Institute (DMI) and the Norwegian Meteorological Institute (MET Norway).
 
In addition it may be appropriate to cite one or more of the OSI-SAF experiment design articles (see below).

The reprocessing of sea ice concentration is obtained from passive microwave satellite data over the polar regions.
It is based on atmospherically corretected signal and an optimal sea ice concentration algorithm.
The reprocessed data set is available for free from the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF).
