This dataset contains pixels sampled from Sentinel-2 images. 198 scenes on the period going from early 2016 to the end of 2020 from 128 different MGRS tiles were used. For each acquisition, the data was obtained at 2 processing levels: 1C (from PEPS, CNES' mirror of Sentinel data) and 2A (from Theia's catalogue), the latter having been produced by the MAJA processor. For each acquisition, 100,000 pixels where sampled. Only non-saturated pixels were selected, regardless of their cloud or shadow status. Pixel positions were selected on the 20m resolution grid. For each 20m pixel position, the following information was recorded: - whether the pixel was detected as a cloud or a shadow (without distinction of these 2 states), - the reflectance in the 20m bands for levels 1C and 2A, - the reflectance of the 4 corresponding pixels of each of the 10m resolution bands for levels 1C and 2A, - the reflectance at the 20m pixel position of the 60m resolution bands after bicubic resampling for level 1C. - the solar and viewing angles for each pixel. For each sampled scene, a CSV file with the name TILE_DATE_samples.csv (for example T05KRA_20171124_samples.csv) is provided. Each row in the file corresponds to a pixel. The columns provide the following variables: - An integer used as unique identifier of the pixel in the file. - The tile name in TIJXYZ format. - The date in YYYMMDD format. - The coverage: the percentage of the tile covered by the relative orbit of the acquisition. - The x and y integer coordinates of the 20m. resolution pixel in the array. - The reflectances of the 4 10 m resolution pixels corresponding to the 20 m. resolution pixels. The columns are named using the format Level_Band_i with Level being L1C or L2A, and i in {1, 2, 3, 4}. For the band, we keep the ESA (L1C) and Theia (L2A) respective nomenclatures, so we have L1C_B02_1 but L2A_B2_1. - The reflectances of the 20 m resolution bands with columns named Level_Band and the same band name conventions, so we have L1C_B05 and L2A_B5. - The reflectances of the L1C 60m resolution bands resampled to the 20m grid. The 3 columns are named L1C_B01, L1C_B09, L1C_B10. - The reflectances of all the bands (10m and 20m resolution bands for L1C and L2A and the 60 m resolution bands for L1C) resampled to a 60 m resolution grid. The columns are named for instance L1C_B02_60 or L2A_B7_60. - The solar Zenith and Azimuth angles: sun_zen, sun_az: - The sensor Zenith and Azimuth angles split into even and odd detectors (inc_even_zen, inc_odd_zen, inc_even_az, inc_odd_az). The angles values are not recorded (empty value) for the detector to which the pixel does not belong to. - A binary value (CLM) for the cloud and cloud shadow mask (0 if the pixel is clear, 1 if it is a cloud or a cloud shadow). This information is retrieved from the L2A masks. The list of column names is the following: - tile - date - coverage - x - y - L1C_B02_0 - L1C_B02_1 - L1C_B02_2 - L1C_B02_3 - L1C_B03_0 - L1C_B03_1 - L1C_B03_2 - L1C_B03_3 - L1C_B04_0 - L1C_B04_1 - L1C_B04_2 -
