Announcement of Opportunity for S3VT (Sentinel-3 Validation Team)

In the framework of a Copernicus collaborative agreement ESA and EUMETSAT invite interested groups and individuals to support the Sentinel-3 Validation Team (S3VT).

Activity - Projects

Auroral Electrojet and auroral Boundaries estimated from Swarm observations

In the Swarm-AEBS project, a set of new Swarm data products that characterise the auroral electrojets and auroral oval boundaries will be derived from Swarm magnetic field measurements.

Mission - Copernicus Sentinels

Copernicus Sentinel-3

Copernicus Sentinel-3 is an European Earth Observation satellite mission developed to support Copernicus ocean, land, atmospheric, emergency, security and cryospheric applications.

Activity - Projects

Dragon 2 Cooperation Programme

The Dragon 2 Programme focussed on the exploitation of ESA, ESA's Third Party Missions and Chinese Earth observation data for science and applications development in land, ocean and atmospheric applications.

Tools - Catalogues

Tools - Catalogues

FedEO

FedEO is a data catalogue that provides a unique entry point to a number of scientific catalogues and services for, but not limited to, European and Canadian missions.

Mission - Earth Explorers

GOCE

ESA's Gravity field and Ocean Circulation Explorer (GOCE) mission mapped Earth's geoid very accurately, opening a window into Earth's interior structure as well as the currents circulating within the depths of its oceans.

Activity - General activities

GSCB and LTDP

The Copernicus programme is based on a fleet of European Earth observation satellites, built and operated by ESA, member states and commercial entities. Copernicus will also offer data from non-European satellites.

How Envisat helped to shape global understanding of Earth’s systems

Twenty years have passed since a ground-breaking European spacecraft designed to deliver unprecedented insight into the planet’s changing environment was lofted into orbit.

Mission - Heritage Missions

JERS-1

The overall objectives of JERS-1 (Japanese Earth Resources Satellite) were the generation of global data sets with SAR and OPS sensors aimed at surveying resources, establishing an integrated Earth observation system

Data - EO Sign In Authentication (Open)

JERS-1 OPS (Optical Sensor) Very Near Infrared Radiometer (VNIR) System Corrected Products level 1

The JERS-1 Optical System (OPS) is composed of a Very Near Infrared Radiometer (VNIR) and a Short Wave Infrared Radiometer (SWIR). The instrument has 8 observable spectral bands from visible to short wave infrared. Data acquired by ESA ground stations The JERS-1 OPS products are available in GeoTIFF format. These products are available only for the VNIR sensor. All four bands are corrected. The correction consists in a vertical and horizontal destriping, the radiometry values are expanded from the range [0.63] to the range [0.255]. No geometrical correction is applied on level 1. The pixel size of approximately 18 x 24.2 metres for raw data is newly dimensioned to 18 x 18 metres for System Corrected data using a cubic convolution algorithm. Disclaimer: Cloud coverage for JERS OPS products has not been computed using an algorithm. The cloud cover assignment was performed manually by operators at the acquisition stations. Due to missing attitude information, the Nadir looking band (band 3) and the corresponding forward looking band (band 4) are not well coregistered, resulting in some accuracy limitations. The quality control was not performed systematically for each frame. A subset of the entire JERS Optical dataset was selected and manually checked. As a result of this, users may occasionally encounter issues with some of the individual products. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
