Which band is red in 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.
 

What are the bands in Sentinel 2A?

Sentinel-2A and 2B Satellite Sensor Specifications



MSI covering 13 spectral bands (443–2190 nm), with a swath width of 290 km and a spatial resolution of 10 m (four visible and near-infrared bands), 20 m (six red edge and shortwave infrared bands) and 60 m (three atmospheric correction bands).

Which Sentinel 2 product provides bottom of atmosphere reflectance?

Level-2A product

Level-2A product provides orthorectified Bottom-Of-Atmosphere (BOA) reflectance, with sub-pixel multispectral registration. A Scene Classification map (cloud, cloud shadows, vegetation, soils/deserts, water, snow, etc.) is included in the product.

What is Band 8a in Sentinel-2?

Water vapour retrieval over land is performed with the Atmospheric Pre-corrected Differential Absorption (APDA) algorithm [R4] which is applied to the two Sentinel-2 bands (B8a, and B9). Band 8a is the reference channel in an atmospheric window region. Band 9 is the measurement channel in the absorption region.

Which band is red remote sensing?

Landsat 8-9 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)

What is C-band in Sentinel-1?

The Sentinel-1 mission provides data from a dual-polarization C-band Synthetic Aperture Radar (SAR) instrument at 5.405GHz (C band). This collection includes the S1 Ground Range Detected (GRD) scenes, processed using the Sentinel-1 Toolbox to generate a calibrated, ortho-corrected product.

What are bands in satellite images?

Throughout the CBC guides we use the term “band” to refer to the layers in an image, such as a satellite image or an image from a digital photograph. We use the term “channel” to represent the different colors or light that are used to display an image on a computer screen.
 

What band is Sentinel-1?

C-band synthetic aperture radar

SENTINEL-1 carries a single C-band synthetic aperture radar instrument operating at a centre frequency of 5.405 GHz.

What is Sentinel-2’s Red Edge Band and what is it used for?

The three 20m ‘red edge’ bands of Sentinel-2 multispectral instrument provide key information on the state of vegetation. Using the ESA SNAP Toolbox was performed the resampling, the RGB combination and the rendering.

What is red edge in remote sensing?

Red edge refers to the region of rapid change in reflectance of vegetation in the near infrared range of the electromagnetic spectrum.

How many vegetation red edge spectral bands are there for Sentinel-2?

three spectral bands

S2 band configuration provides three spectral bands in the red-edge region: bands B5 and B6 located at the sharp edge, and B7 that is located at the shoulder of the NIR plateau.
