served from IRI/LDEO Climate Data Library

TRENBERTH Monthly mask: Land/Sea/Ice Mask: 0-sea, 1-land, 2-ice data

TRENBERTH Monthly Land/Sea/Ice Mask: 0-sea, 1-land, 2-ice: land determination based on ETOPO5 elevation values at 1/12 deg resolution. Legend: 1-LAND ie. at least 75% of region is land even if grid point is ocean 0-SEA ie. less than 25% of region is land even if grid point is land 2-SEAICE as inferred from the Alexander-Mobley SST climatology where SST < -2.0 Celsius for the month.
