Load Sentinel-1 RTC backscatter as a lazy xarray.Dataset.

Parameters:

  • aoi – The usual spatial and temporal inputs.

  • time – The usual spatial and temporal inputs.

  • bands – Polarizations ("vv", "vh"; OPERA also has "hh"/"hv").

  • source – "planetary-computer" (default), "opera-rtc-s1" or "gee".

  • units – "dB" (default) or "linear power".

  • groupby – odc-stac grouping; defaults to "sat:absolute_orbit" on Planetary Computer (one raster per pass) and "solar_day" for OPERA bursts.

  • border_noise – Mask the falsely low values along scene edges in pre-2018 scenes (easysnowdata.processing.remove_border_noise()).

  • mask – Include the OPERA layover/shadow mask (OPERA route only).

  • orbit_state – Keep only ascending or descending passes (Planetary Computer).
