Reliability shapefile for slope corrected orthometric heights of Antarctica derived from ERS radar altimetry
Entry ID: ERS_REL_ANT


Summary
Abstract: Shapefile indicating areas of valid and invalid slope corrected orthometric heights derived from ERS Radar Altimetry. Refer to metadata record GRI_ORT_SLC_FIN for more information.

ESA's two European Remote Sensing (ERS) satellites, ERS-1 and 2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.

ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.

The ERS-1 mission ended on 10 March 2000 and ERS-2 was retired on 05 September 2011.

Quality The reliability shapefile was generated from the file of slope corrected orthometric heights (refer to metadata record GRI_ORT_SLC_FIN). All points in the file were used. An area was generated around each polygon using the Thiessen command in Arc/Info. This creates polygon boundaries that fall midway between adjacent points. Polygons surrounding invalid points were merged and the polygons around valid points were likewise merged (Arc/Info Dissolve command was used). This produced a shapefile of areas containing valid points and invalid points. The number of points inside invalid areas was also attached to the invalid polygons (Count field).
Access Constraints Available unprojected or in a Polar Stereographic projection with true scale at 71 degrees S.
