NOAA@NSIDC would like to make users aware of a change to the processing frequency for the U.S. National Ice Center Arctic and Antarctic Sea Ice Concentration and Climatologies in Gridded Format data set. The USNIC has changed to creating their Arctic and Antarctic Sea Ice Charts from weekly to every other week. The Arctic and Antarctic charts will be processed on alternating weeks. For example, the Arctic charts were processed for the week of 18 April 2022, and the Antarctic will be processed the following week, and so on alternating each week. This change was implemented due to the time intensity of creating the charts and the need for the most prudent use of the USNIC analyst’s time.
