    dct:description """DEA Surface Reflectance Nadir corrected Bidirectional reflectance distribution function Adjusted Reflectance Terrain corrected (NBART) Sentinel-2B Multispectral Instrument (MSI) is part of a suite of Digital Earth Australia's (DEA) Surface Reflectance datasets that represent the vast archive of images captured by the US Geological Survey (USGS) Landsat and European Space Agency (ESA) Sentinel-2 satellite programs, which have been validated, calibrated, and adjusted for Australian conditions — ready for easy analysis.

<b>Background:</b>
This is a sub-product of DEA Surface Reflectance (Sentinel-2B MSI). See the parent product for more information.

Reflectance data at top of atmosphere (TOA) collected by Sentinel-2B MSI sensors can be affected by atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect.

Surfaces with varying terrain can introduce inconsistencies to optical satellite images through irradiance and bidirectional reflectance distribution function (BRDF) effects. For example, slopes facing the sun appear brighter compared with those facing away from the sun. Likewise, many surfaces on Earth are anisotropic in nature, so the signal picked up by a satellite sensor may differ depending on the sensor’s position.

These need to be reduced or removed to ensure the data is consistent and can be compared over time.

<b>What this product offers:</b>
This product takes Sentinel-2B MSI imagery captured over the Australian continent and corrects the inconsistencies across the land and coastal fringe. It achieves this using Nadir corrected Bi-directional reflectance distribution function Adjusted Reflectance (NBAR).

In addition, this product has a terrain illumination correction applied to correct for varying terrain.

The resolution is a 10/20/60 m grid based on the ESA level 1C archive.

<b>Applications:</b>
- The development of derivative products to monitor land, inland waterways and coastal features, such as:
               -  urban growth
               -  coastal habitats
               -  mining activities
               -  agricultural activity (e.g. pastoral, irrigated cropping, rain-fed cropping)
               -  water extent
- The development of refined information products, such as:
               -  areal units of detected surface water
               -  areal units of deforestation
               -  yield predictions of agricultural parcels
- Compliance surveys
- Emergency management""" ;
