Global continuous reprocessed sea ice concentration offline product (OSI-430)

The continuous reprocessed sea ice concentration offline product (OSI-430) has been introduced to continue the reprocessed sea ice concentration data set (OSI-409-a) in a delayed manner. The continuous reprocessed product has exactly the same characteristics as the reprocessed data set, in format and algorithms. The only difference is that operational input data are used for the continuous reprocessed product.

The continuous reprocessed product is delivered on a daily basis with a monthly delay (33 days), as the processing requires 31 days of data to produce the climate consistent product.

More details about the format and algorithms can be found in the section about the reprocessed data set, and in the product documentation mentioned below.

Download data set

The sea ice concentration continuous reprocessed offline product can be downloaded at this anonymous FTP server:

ftp://osisaf.met.no/reprocessed/ice/conc-cont-reproc/v1p2.

The data are organized in year/month directories.

Product history

  • version 1.2: Covers the period 16th April 2015 onwards. Is consistent with the OSI-409-a v1.2 reprocessed data set.

Validation

The sea ice concentration continuous reprocessed product has been compared to National Ice Center ice charts from both northern and southern hemisphere. In general the ice charts have higher ice concentrations than the OSISAF product. However, there is no trend from year to year.

Documentation

More technical details about the data set can be found in the
Product User Manual
and the
Algorithm Theoretical Basis Document.

Validation results can be found in the Validation Report.

Quicklooks

Quicklook of the continuous reprocessed product will be available here in August 2015.
