What are the bands of Sentinel 2?
Sentinel 2 Bands
- Its blue (B2), green (B3), red (B4), and near-infrared (B8) channels have a 10-meter resolution.
- Next, its red edge (B5), near-infrared NIR (B6, B7 and B8A) and short-wave infrared SWIR (B11 and B12) have a ground sampling distance of 20 meters.
What is the difference between Sentinel 2A and 2B?
Sentinel-2A was launched on 23 June 2015, while Sentinel-2B satellite was launched on 7 March 2017. When two sensors are operated simultaneously, the mission’s revisit time is about 5 days, while about 10 days with one satellite in operation.
What can I monitor with Sentinel 2?
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.
Does Sentinel 2 have a thermal band?
Sentinel 2 has not consist of any thermal band while Landsat-8 have it (band 10 and 11).
Is Sentinel-2 still operational?
Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space….Sentinel-2.
|Maiden launch||Sentinel-2A 23 June 2015|
|Last launch||Sentinel-2B 7 March 2017|
How many bands are in the Sentinel-2?
13 spectral bands
SENTINEL-2 carries an optical instrument payload that samples 13 spectral bands: four bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution. The orbital swath width is 290 km.
How old is Sentinel-2?
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.
What is Sentinel 2 mission?
SENTINEL-2. The objective of SENTINEL-2 is land monitoring, and the mission will be composed of two polar-orbiting satellites providing high-resolution optical imagery. Vegetation, soil and coastal areas are among the monitoring objectives. The first SENTINEL-2 satellite was launched in June 2015.
What is Copernicus Sentinel 2 mission?
The mission The Copernicus Sentinel-2 mission is based on a constellation of two identical satellites in the same orbit. Each satellite carries an innovative wide swath high-resolution multispectral imager with 13 spectral bands for a new perspective of our land and vegetation.
How do the two Sentinel-2 satellites operate together?
To achieve frequent revisits and high mission availability, two identical Sentinel-2 satellites (Sentinel-2A and Sentinel-2B) operate together. The satellites are phased 180 degrees from each other on the same orbit. This allows for what would be a 10-day revisit cycle to be completed in 5 days.
What is the Sentinel Monitoring web application?
The Sentinel Monitoring web application offers an easy way to observe and analyse land changes based on archived Sentinel-2 data. The following two main products are generated by the mission: Level-1C: Top-of-atmosphere reflectances in cartographic geometry (combined UTM projection and WGS84 ellipsoid).
