ESA Sea Surface Temperature Climate Change Initiative (ESA SST CCI): Along-Track Scanning Radiometer (ATSR) level 3 uncollated data (L3U) long-term product version 1.1

The ESA Sea Surface Temperature Climate Change Initiative (ESA SST CCI) dataset accurately maps the surface temperature of the global oceans over the period 1991 to 2010 using observations from many satellites. The data provides an independently quantified SST to a quality suitable for climate research.

The ESA SST CCI ATSR (Along-Track Scanning Radiometer) Long Term Product version 1.1 consists of stable, low-bias sea surface temperature (SST) data covering the period 08/1991 - 04/2012. The L3U data product provides these SST data regridded onto a global longitude-latitude grid.

The version 1.1 data is an update to the version 1.0 dataset.

Data availability and file format The L3U (Level 3 Uncollated) data from the series of Along Track Scanning Radiometer (ATSR) sensors consists of a single orbit per file on a 0.05° regular latitude-longitude grid. These start in August 1991. Each file contains two sets of SSTs. The first set provides a measure of the temperature of the skin of the water at the time it was observed; the second set are estimates of the temperature at 20 cm depth and at either 1030 h or 2230 h local time. Each SST has associated with it a total uncertainty estimate, and uncertainty estimates for various contributions to that total uncertainty. The data are stored in NetCDF-4 format files. Data arrays in NetCDF files are known as ‘variables’ and each variable has metadata stored with it. Please read the ESA CCI SST Product User Guide, available here before using the data. There is also a Quick Start Guide here. Access to the ESA SST CCI ATSR L3U long term product is available through our data browser here or via ftp at /neodc/esacci_sst/data/lt/ATSR/L3U/v01.1

The L3U (Level 3 Uncollated) data from the series of Along Track Scanning Radiometer (ATSR) sensors consists of a single orbit per file on a 0.05° regular latitude-longitude grid. These start in August 1991.

Each file contains two sets of SSTs. The first set provides a measure of

the temperature of the skin of the water at the time it was observed; the

second set are estimates of the temperature at 20 cm depth and at either

1030 h or 2230 h local time. Each SST has associated with it a total uncertainty

estimate, and uncertainty estimates for various contributions to

that total uncertainty.

The data are stored in NetCDF-4 format files. Data arrays in NetCDF files are

known as ‘variables’ and each variable has metadata stored with it. Please read the ESA CCI SST Product User Guide, available here before using the data. There is also a Quick Start Guide here.
