What is Meris and ESA Sentinel 3 data?
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).
What does MERIS stand for?
Medium Resolution Imaging Spectrometer
MERIS (Medium Resolution Imaging Spectrometer) is one of the main sensors onboard the ENVISAT-1, which was launched in March 2002 by the European Space Agency (ESA).
What can Envisat detect?
It can detect changes in surface heights with sub-millimeter precision. It served as a data link for ERS 1 and ERS 2, providing numerous functions such as observations of different polarities of light or combining different polarities, angles of incidence and spatial resolutions.
What is the spatial resolution of Sentinel 3?
300m

What happened to Envisat?
The European Space Agency declared the death of its massive Earth-observing satellite Envisat today (May 9) after a month of mysterious silence from the school bus-size spacecraft.
How is Kessler syndrome prevented?
There is no current system to remove old satellites or sweep up bits of debris in order to prevent a Kessler event. Instead, space debris is monitored from Earth, and new rules require satellites in low-Earth orbit be deorbited after 25 years so they don’t wind up adding more space junk.

What is Sentinel database?
The Sentinel Distributed Database is the collection of harmonized datasets from many different Data Partners. These datasets are all in the Sentinel Common Data Model format.
What is Sentinel-2 MSI?
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
What is the difference between Sentinel-3A and 3B?
The Sentinel-3 orbit is a near-polar, sun-synchronous orbit with a descending node equatorial crossing at 10:00 h Mean Local Solar time. Sentinel-3B’s orbit is identical to Sentinel-3A’s orbit but flies +/-140° out of phase with Sentinel-3A.
How can I download data from the Envisat Meris mission?
Download data from the Envisat MERIS mission through the MERIS Online Dissemination Service. The data is freely available to registered users. All Envisat MERIS products, in accordance with ESA Earth Observation Data Policy, are freely available to users. Read more about the available MERIS products:
What’s new at Envisat?
More advanced imaging radar, radar altimeter and temperature-measuring radiometer instruments extended ERS data sets. This was supplemented by new instruments including a medium-resolution spectrometer sensitive to both land features and ocean colour. Envisat also carried two atmospheric sensors monitoring trace gases.
What does Meris stand for?
Bahamas – MERIS – 24 January 2004. The Medium Resolution Imaging Spectrometer (MERIS) was a programmable spectrometer on the Envisat mission, operating in the solar reflective spectral range. Although primarily dedicated to ocean colour observations, MERIS broadened its scope of objectives to atmospheric and land surface related studies.
What new instruments did Envisat carry?
This was supplemented by new instruments including a medium-resolution spectrometer sensitive to both land features and ocean colour. Envisat also carried two atmospheric sensors monitoring trace gases. The Envisat mission ended on 8 April 2012, following the unexpected loss of contact with the satellite.
