Usage

Stare

import doppy

stare = doppy.product.Stare.from_halo_data(
    data=LIST_OF_STARE_FILE_PATHS,
    data_bg=LIST_OF_BACKGROUND_FILE_PATHS,
    bg_correction_method=doppy.options.BgCorrectionMethod.FIT,
)

stare.write_to_netcdf(FILENAME)

Stare with depolarisation

import doppy

stare_depol = doppy.product.StareDepol.from_halo_data(
    co_data=LIST_OF_STARE_CO_FILE_PATHS,
    co_data_bg=LIST_OF_BACKGROUND_CO_FILE_PATHS,
    cross_data=LIST_OF_STARE_CROSS_FILE_PATHS,
    cross_data_bg=LIST_OF_BACKGROUND_CROSS_FILE_PATHS,
    bg_correction_method=doppy.options.BgCorrectionMethod.FIT,
    polariser_bleed_through=0,
)

stare_depol.write_to_netcdf(FILENAME)

Wind

import doppy

wind = doppy.product.Wind.from_halo_data(
    data=LIST_OF_WIND_SCAN_HPL_FILES,
)

# You can also pass instrument azimuth offset in degrees as an option
wind = doppy.product.Wind.from_halo_data(
    data=LIST_OF_WIND_SCAN_HPL_FILES,
    options=doppy.product.wind.Options(azimuth_offset_deg=30),
)

# For windcube wls200s use
wind = doppy.product.Wind.from_windcube_data(
    data=LIST_OF_VAD_NETCDF_FILES,
)

# For windcube wls70 use
wind = doppy.product.Wind.from_wls70_data(
    data=LIST_OF_RTD_FILES,
)

wind.write_to_netcdf(FILENAME)
