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 is ESA Sentinel?

ESA is developing a new family of missions called Sentinels specifically for the operational needs of the Copernicus programme. Each Sentinel mission is based on a constellation of two satellites to fulfil revisit and coverage requirements, providing robust datasets for Copernicus services.

What is Sentinel-3 used for?

The main objective of the Sentinel-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring.

When did Sentinel-2 start?

June 23, 2015
Sentinel-2/Start dates
The Sentinel-2A satellite was launched by ESA on June 23, 2015, and operates in a sun-synchronous orbit with a 10-day repeat cycle. A second identical satellite (Sentinel-2B) was launched March 7, 2017 and is operational with data acquisitions available on EarthExplorer.

When did Sentinel 2 start?

How far back does Sentinel 2 go?

It aims at monitoring variability in land surface conditions, and its wide swath width (290 km) and high revisit time (10 days at the equator with one satellite, and 5 days with 2 satellites under cloud-free conditions which results in 2-3 days at mid-latitudes) will support monitoring of Earth’s surface changes.

How many Sentinel-3 satellites are there?

2 satellites
Sentinel-3 is an Earth observation satellite series developed by the European Space Agency as part of the Copernicus Programme. It currently (as of 2020) consists of 2 satellites: Sentinel-3A and Sentinel-3B.

Is Sentinel 2 still operational?

Sentinel-2A has been in orbit since 23 June 2015, and Sentinel-2B launched on 7 March 2017….Platform and payload.
