This function plots daily Antarctic sea ice concentration from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data or Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations.
ci = seaice(...,'noplot')
[ci,lat,lon,x,y,h] = seaice(...)
seaice plots a the most recent available sea ice concentration map.
seaice(Date) specifies a date from October 26, 1978 to present. Date can be entered as a string in just about any common format for writing dates, or in Matlab's datenum format. Any date after January 1 of the current year will use Near-Real-Time data. This may potentially cause errors in the first week of the year.
seaice(...,'xy') plots in polar stereographic (x,y) coordinates. By default if you do not have Matlab's Mapping Toolbox, the 'xy' option is selected automatically. If you do have Matlab's Mapping Toolbox but you'd still like to plot your data as meters "eastings and northings", include the 'xy' tag.
seaice(...,'label',LabelLocation) specifies a location for date label. Location must be specified in cardinal coordinates (e.g., 'north' for top) or 'none' to place no label. Default LabelLocation is 'southwest', meaning the lower left corner of the map.
ci = seaice(...,'noplot') does not plot any data, but returns a gridded sea ice concentration. This may be useful for populating a 3D matrix of sea ice concentrations.
[ci,lat,lon,x,y,h] = seaice(...) returns a whole slew of good information, including lat/lon grids, handle h of plotted object(s), and x,y grids.
