What are the bands of Sentinel 2?
The spatial resolution of SENTINEL-2 is dependent on the particular spectral band:
- 10 metre spatial resolution: Figure 1: SENTINEL-2 10 m spatial resolution bands: B2 (490 nm), B3 (560 nm), B4 (665 nm) and B8 (842 nm)
- 20 metre spatial resolution:
- 60 metre spatial resolution:
How many bands does Sentinel 2 have?
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.
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.
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.
| Spacecraft mass, power | 1140 kg (at launch), 1700 W |
|---|---|
| Spacecraft design life | 7 years with propellant for 12 years of operations |
Which band is near-infrared for Sentinel-2?
Sentinel-2 carries the Multispectral Imager (MSI). This sensor delivers 13 spectral bands ranging from 10 to 60-meter pixel size. Its blue (B2), green (B3), red (B4), and near-infrared (B8) channels have a 10-meter resolution.
Which band of Sentinel-2 image is NIR band?
Spectral bands
| Sentinel-2 bands | Sentinel-2A | |
|---|---|---|
| Central wavelength (nm) | Spatial resolution (m) | |
| Band 8 – NIR | 832.8 | 10 |
| Band 8A – Narrow NIR | 864.7 | 20 |
| Band 9 – Water vapour | 945.1 | 60 |
What is the temporal resolution of Sentinel-2A?
Temporal Resolution The satellites in the Sentinel-2 constellation will provide a revisit time of five days at the equator in cloud-free conditions.
Does Sentinel-2 have thermal band?
Sentinel 2 has not consist of any thermal band while Landsat-8 have it (band 10 and 11). ASTER is also consist of the 5 Thermal bands (resolution is of 90 meters and resampled upto 15 meters).
What is the difference between Landsat-8 and Sentinel-2?
Classification of all Sentinel-2 bands as well as Sentinel-2 bands common to Landsat-8 produced an overall accuracy, that is 5\% and 4\% better than Landsat-8. The combination of Landsat-8 and Sentinel-2 red-edge bands resulted in a 4\% accuracy improvement over that of Landsat-8.
What are Sentinel-2 images?
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters.
What is Sentinel-2 satellite used for?
As well as monitoring plant growth, Sentinel-2 can be used to map changes in land cover and to monitor the world’s forests. It also provides information on pollution in lakes and coastal waters. Images of floods, volcanic eruptions and landslides contribute to disaster mapping and help humanitarian relief efforts.
What resolution is Sentinel-2 imagery?
10 m to 60 m
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters.
