Description
Summary:These data are ICESat GLA12 428 spaceborne laser altimetry data . We have modified the original ICESat data by applying an improved tide model (CATS2008a) as well as the recommended corrections for saturation and surface air pressure (the inverse barometer effect). We provide these data as 9 zipped ArcGIS shapefilesets, split by region.Each zip file contains ArcGIS shapefile sets of ICESat GLA12 428 data in polar stereographic projection grouped typically into 2-year periods denoted by the numbers after the region identifier, e.g. FRIS_67_PS indicates Filchner-Ronne data from 2006 and 2007.The shapefiles contain point data with the following attributes:Attribute Description- daysum: Serial date (decimal days)- year: Year of acquisition- float: Flag 1 or 0 where 1 indicates that the data fell within the domain of CATS2008a tide model. Data flagged 1 are over an ice shelf or ocean.- gain: ICESat processing gain value as defined here http://nsidc.org/data/docs/daac/glas_icesat_l1_l2_global_altimetry.gd.html- ...
