Abstract

This dataset contains high latitude sea level anomalies produced by DTU (Technical University of Denmark) and TUM (Technical University of Munich) as part of the ESA Sea Level CCI (Climate Change Initiative) project, covering both the Arctic and Antarctic regions.

The data comprises weekly means from August 1991 to April 2017 and has been obtained using satellite altimetry data from four satellite missions: ERS1 (weeks 0 - 217); ERS2 (weeks 218 - 573); Envisat (weeks 574 - 1020); CryoSat-2 (weeks 1021 - 1336).

Two datasets are available: dataset #1 is based on the ALES+ retracking without correction of the inverse barometer whereas dataset #2 has been corrected for this effect.

Dataset #1 is provided both 'masked' and 'unmasked', where the masked data have been masked using sea ice concentrations downloaded from osisaf.met.no/p/ice. Dataset #2 is provided both 'masked' and 'unmasked', where the masked data have had data points retrieved over land removed from the files.

Data lineage:

The product has been developed within the sea level project of the European Space Agency (ESA) Climate Change Initiative. A copy has been transferred to CEDA as part of the ESA CCI Open Data Portal project.

Data Quality:
Data are as provided by the Sea Level CCI project team
File Format:
Data are in ascii format. For dataset 1 the columns are: Longitude, Latitude, Height (always 0), Sea level anomaly (SLA), SLA error, Data origin (mission). The time in the filename denotes the beginning of the data, and files contain weekly means. For Dataset 2 the columns are: Longitude, Latitude, Height (always 0), Sea level anomaly (SLA). The filename states the region and the month and year of the dataset (YYYYMM).
