See the parent product for more information.\n\nReflectance 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.\n\nSurfaces 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\u2019s position.\n\nThese need to be reduced or removed to ensure the data is consistent and can be compared over time.\n\n<b>What this product offers:</b>\nThis 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).\n\nIn addition, this product has a terrain illumination correction applied to correct for varying terrain.\n\nThe resolution is a 10/20/60 m grid based on the ESA level 1C archive.\n\n<b>Applications:</b>\n- The development of derivative products to monitor land, inland waterways and coastal features, such as:\n               -  urban growth\n               -  coastal habitats\n               -  mining activities\n               -  agricultural activity (e.g. pastoral, irrigated cropping, rain-fed cropping)\n               -  water extent\n- The development of refined information products, such as:\n               -  areal units of detected surface water\n               -  areal units of deforestation\n               -  yield predictions of agricultural parcels\n- Compliance surveys\n- Emergency management", "num_resources": 2, "num_tags": 7, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/geoscience-australia-sentinel-2b-msi-nbart-collection-3-dea-surface-reflectance-nbart-sentinel-", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]}", "state": "active", "temporal_coverage_from": "2022-04-20 01:46:38+00", "title": "Geoscience Australia Sentinel-2B MSI NBART Collection 3 -
