Abstract
The AATSR Reprocessing for Climate (ARC) dataset consists of Advanced Along-Track Scanning Radiometer (AATSR) multimission data which has been reprocessed using various algorithms and in-situ contemporaneous measurements, to provide update retrievals of Sea Surface Temperature (SST) and assess their accuracy.
This dataset contains version 1.1 of the Level 3 sea surface temperature data product produced by the ARC project team.
The main ARC objective was to reduce regional biases in retrieved sea surface temperature (SST) to less than 0.1 K for all global oceans while creating a very homogeneous record with a stability (lack of drift in the observing system and analysis) of 0.05 K decade.

| Access rules: |
Public data: access to these data is available to both registered and non-registered users.
Use of these data is covered by the following licence(s): http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
ARC data is derived from the aatsr_multimission dataset held at the NEODC. ARC also uses UKMO Buoy data to provide ground calibration data (GHRSST). Data was supplied to the NEODC by Owen Embury at the University of Edinburgh. |
| Data Quality: |
ARC data is reprocessed (A)ATSR series data with the intention of providing better constrained SST estimates than the original ESA SSE AATSR product. ARC data incorporates improved algorithms for estimation of SST using ground based in -situ SST measurements (GHRSST) and estimation of air column Saharan dust content.
