Sentinel-2 is a wide-swath, high-resolution, multi-spectral\n", "imaging mission supporting Copernicus Land Monitoring studies,\n", "including the monitoring of vegetation, soil and water cover,\n", "as well as observation of inland waterways and coastal areas.
The Sentinel-2 L2 data are downloaded from scihub. They were\n", "computed by running sen2cor. WARNING: ESA did not produce L2 data\n", "for all L1 assets, and earlier L2 coverage is not global.
The assets contain\n", "12 UINT16 spectral bands representing SR scaled by 10000 (unlike in L1 data,\n", "there is no B10). There are also several more L2-specific bands (see band\n", "list for details). See the\n", "Sentinel-2 User Handbook\n", "for details. In addition, three QA bands are present where one\n", "(QA60) is a bitmask band with cloud mask information. For more\n", "details, see the full explanation of how cloud masks are computed.
EE asset ids for Sentinel-2 L2 assets have the following format:\n", "COPERNICUS/S2_SR/20151128T002653_20151128T102149_T56MNN. Here the\n", "first numeric part represents the sensing date and time, the\n", "second numeric part represents the product generation date and\n", "time, and the final 6-character string is a unique granule identifier\n", "indicating its UTM grid reference (see MGRS).
Clouds can be removed by using\n", "COPERNICUS/S2_CLOUD_PROBABILITY.\n", "See\n", "this tutorial\n", "explaining how to apply the cloud mask.
