About ATSR-1


The Along Track Scanning Radiometer (ATSR-1) on board ERS-1 consisted of an Infra-Red Radiometer (IRR) and a Microwave Sounder (MWS). The IRR had four channels and was used for measuring sea-surface temperatures (SST) and cloud-top temperatures,The MWS was a two channel passive radiometer.  

The IRR was designed and constructed by a consortium, consisting of Rutherford Appleton Laboratory , Oxford University , Mullard Space Science Laboratory , the UK Meteorological Office and CSIRO in Australia. The MWS was built under the responsibility of Centre de Recherche en Physique de l'Environnement (CRPE) and was physically attached to the IRR and its data was merged with that of the IRR prior to transmission to the ground receiving stations. Both are nationally- funded experiments resulting from an ESA Announcement of Opportunity for a scientific add-on package. The ERS-1 mission ended on 10 March 2000.


ATSR-1 Data


Download data from the ERS-1 mission through the ESA Online Dissemination System. The ATSR-1 data is freely available to registered users.


Tools available for visualising, processing and analysing ERS-1 data:

Sentinel-3 toolbox

Sentinel-3 Toolbox consists of a rich set of visualisation, analysis and processing tools for the exploitation of OLCI and SLSTR data from the upcoming Sentinel-3 mission. As a multi-mission remote sensing toolbox, it supports ESA's Envisat mission (MERIS and AATSR instruments).

Sentinel Application Platform

Sentinel Application Platform (SNAP) is a common architecture for all Sentinel Toolboxes. It is ideal for Earth Observation processing and analysis due to technological innovations.

Quality Control is monitoring routinely the status of the spacecraft (payload and platform) and to check if the derived products meet the quality requirements along mission life-time.

ATSR-1 Cal/Val

Calibration allows the traceability of satellite sensor data to physical standards, and provides a routine check on instrument performance.

Validation establishes the link between EO measurements from space to derived data products and measurements on the ground, allowing for the verification of the algorithms, and models used to derive parameters and data products.

Calibration Activities and Reports are available for ATSR-1.

ATSR-1 Quality Control Reports

ATSR-1 Quality Control Reports detail the availibility of products, any anomalies and the Pick-up Noise issue that affected some products.
