Load VIIRS snow cover as a lazy xarray.Dataset (time, y, x).

Parameters:

  • aoi – The usual spatial and temporal inputs.

  • time – The usual spatial and temporal inputs.

  • product – "VNP10A1F" (cloud-gap-filled, default), "VNP10A1", or a NOAA-20 sibling ("VJ110A1", "VJ110A1F").

  • variables – Data fields to read; the product’s main field by default. The others are Cloud_Persistence, Basic_QA and Algorithm_Bit_Flags_QA.

  • mask – True NaN-masks the sentinel values; the default keeps the raw byte with its CF flags (see easysnowdata.processing.binary_snow()).
