NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 2
This data set has been replaced with a newer version. Note: If necessary, Version 2 can be accessed by contacting NSIDC Users Services at nsidc@nsidc.org. However, we highly suggest using the latest version of this data set.
This data set provides a Climate Data Record (CDR) of sea ice concentration from passive microwave data. It provides a consistent, daily and monthly time series of sea ice concentrations from 09 July 1987 through the most recent processing for both the north and south polar regions. In addition, three other sea ice concentration products are included with the CDR that extend the sea ice measurements back to 26 October 1978. However, these three products are not included in the official CDR because processing the older data in a way that follows the standards of a CDR is not currently possible. All data are on a 25 km x 25 km grid.
There is a more recent version of these data.
- Two new variables added to the netCDF files:
- melt_onset_day_seaice_conc_cdr
- melt_onset_day_seaice_conc_monthly_cdr
- Calculation of melt_start_detected flag in the qa_of_seaice_conc_cdr variable was updated
See the documentation for full details on these variables.
