Global optical kernel moisture dataset (kNDMI and kSVMI), Part 01: 2000-04 to 2001-12

This record contains Part 01 of the global optical kernel moisture dataset (kNDMI and kSVMI) and covers monthly products from April 2000 to December 2001. The dataset is a global monthly 1 km GeoTIFF product derived from MODIS surface reflectance and snow products using a Google Earth Engine workflow. For each month, this record provides two GeoTIFF files: 1. INDEX_YYYY_MM.tif Bands: (1) kNDMI_005_fixed (2) kNDMI_020_max (3) kSVMI (4) snow_fraction 2. QA_YYYY_MM.tif Bands: (1) valid_mask (2) qa_reason (3) n_valid_obs The INDEX files are stored as Float32 with NoData = -9999. The QA files are stored as UInt16. The qa_reason band uses a bitmask scheme for invalid pixels: 1 = no valid observation 2 = cloud contamination 4 = cloud shadow 8 = snow present during the month 16 = reflectance out of valid range This record is one temporal partition of the complete dataset spanning April 2000 to December 2024. The Google Earth Engine processing code used to generate the dataset is archived separately on Zenodo: https://doi.org/10.5281/zenodo.19687889
