Climatological maps of sea ice variability for the Antarctic marginal ice zone
Description
Monthly climatologies of a statistical indicator of sea ice variability computed from daily maps of sea ice concentration (SIC) from satellites (Vichi, 2022). The sigma_SIA indicator is based on the standard deviation of SIC daily anomalies computed over the monthly time scales, using a monthly climatology as the baseline. The following files have been derived from NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 4 (https://doi.org/10.7265/efmz-2t65 and used in Vichi (2022). The code to produce them is available at the following repository https://github.com/mvichi/antarcticMIZ (DOI:10.25375/uct.21103363) NSIDC_cdr_clim_m_sigmaSIA.nc: Climatological monthly sigma_SIA (climatological 'pooled' monthly std of daily anomaly) from NOAA/NSIDC CDR Southern Hemisphere Sea Ice Concentration NSIDC_cdr_clim_m_maskMIZ.nc: Climatological mask of the MIZ extent using a sigma_SIA>0.1 criterion NSIDC_cdr_clim_m_sigmaSIA_exceedance.nc: Climatological probability maps of exceeding sigma_SIA>0.1 and sigma_SIA>0.2 These NetCDF files contain 12 monthly arrays with the climatological sigma_SIA computed over the period 1989-2019. Please note that the indicator in this file is in % of SIC, while in the original paper it is presented in fractional units.
