Service
This is the most recent version of these data.
Version Summary
* NSIDC-produced daily and monthly NASA Team (NT) and NASA Bootstrap (BT) variables are included.
* Four variables in the daily files and four variables in the monthly files have been renamed.
* Gap filling implemented using spatial and temporal interpolation. Two new flag variables indicate when interpolation has been done.
* Arctic pole hole filled by spatial interpolation.
* NSIDC’s BT algorithm updated to version 3.1.
* Updated the NASA Team weather filter threshold for the Southern hemisphere instruments.
* In addition to the BT weather and land spillover filters, the NT filters are now also applied.
* Individual land masks have been merged into one composite land mask.

Overview

This data set provides a near-real-time Climate Data Record (CDR) of sea ice concentration from passive microwave data. The Near-real-time NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration (NRT CDR) data set is the near-real-time version of the final NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration (G02202). The NRT CDR is designed to fill the temporal gap between updates of the final CDR, occurring every three to six months, and to provide the most recent data.

Getting started

NSIDC currently archives passive microwave sea ice concentration products based on two algorithms: the NASA Team algorithm and the Bootstrap algorithm. Both algorithms were developed by researchers at the NASA Goddard Space Flight Center in the 1980s.

How To

Currently three NOAA@NSIDC data sets are available in NOAA's PolarWatch Data Catalog. Please note that in the catalog the Climate Data Record (CDR) data sets are split up into Antarctic and Arctic data sets:
