How do I get SENTINEL-2 data?

You can obtain Sentinel 2 data from the ESA and from the USGS. Users must register for free access to data at either site. Currently ESA distributes Sentinel 2 data in entire swaths.

Is SENTINEL-2 data free?

All Sentinel-2 data products are provided free of charge to all data users, including the general public, and scientific and commercial users under the terms and conditions prescribed by the European Commission’s Copernicus Programme.

Why are the two SENTINEL-2 satellites useful for vegetation monitoring?

Conclusions. S-2 provides a great opportunity for global vegetation monitoring due to its enhanced spatial, spectral and temporal characteristics compared with Landsat and SPOT.

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.

How do I view imagery in Sentinel-2?

Users can access the imagery from Sentinel-2 on AWS , or alternatively access Sentinel2Look Viewer, EarthExplorer or the Copernicus Open Access Hub to download the scenes. For information on Sentinel-2 imagery, see Sentinel-2.

What are Sentinel-2 bands?

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.

How far back does Sentinel-2 data 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 1 data free?

Sentinel data products are made available systematically and free of charge to all data users including the general public, scientific and commercial users.

What is Sentinel data used for?

Sentinel-2 (2 satellites) is an optical mission with a multi-spectral instrument mainly for agricultural applications such as crop monitoring and management, vegetation and forest monitoring (e.g. leaf area index, chlorophyll concentration, carbon mass estimations), monitoring land cover change for environmental …

How does Sentinel-2 work?

Two identical SENTINEL-2 satellites operate simultaneously, phased at 180° to each other, in a sun-synchronous orbit at a mean altitude of 786 km. Orbital accuracy is maintained by a dedicated propulsion system. The SENTINEL-2 satellite system was developed by an industrial consortium led by Astrium GmbH (Germany).

Is Sentinel-2 SAR data?

While most scientists using remote sensing are familiar with passive, optical images from the U.S. Geological Survey’s Landsat, NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS), and the European Space Agency’s Sentinel-2, another type of remote sensing data is making waves: Synthetic Aperture Radar, or SAR.

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.

Where can I find and download Sentinel-2 data?

Access Data EarthExplorer, USGS Global Visualization Viewer (GloVis), or the Sentinel2Look Viewer can be used to search, preview, and download Sentinel-2 data. The collection is located under the Sentinel category in EarthExplorer. The current USGS Sentinel-2 archive is only a partial representation of all available acquisitions from ESA.

What is Sentinel-2’s multispectral instrument?

The European Space Agency’s Multispectral Instrument on the Sentinel-2 satellite provides global (from 83 degrees north 56 degrees south latitude) 10-meter resolution, multispectral images every 10 days (2015-present).

Where can I find the USGS Sentinel-2 collection?

The collection is located under the Sentinel category in EarthExplorer. The current USGS Sentinel-2 archive is only a partial representation of all available acquisitions from ESA. Users should expect some delay before ESA’s acquired data becomes available on USGS systems.

What’s new in Sentinel-2 safe?

computing spectral indices and RGB images. New feature: stating from version 1.5.0, Sentinel-2 SAFE archives can be downloaded both from official Copernicus Open Access Hub or from Google Cloud Sentinel-2 bucket (this option can be useful to bypass limitations of ESA Long Term Archive retention time; refer to this post for details).
