get_brightnesstemperature

ASTERimage.get_brightnesstemperature(channel)[source]

Get ASTER L1B reflectances values at TOA.

Spectral radiance values are converted to brightness temperature values in [K] for ASTER’s thermal channels (10-14).

See also

get_radiance(): Reads the raw digital numbers from

ASTER L1B HDF4 files and converts them to radiance values at TOA.

Parameters:

channel (str) – ASTER channel number. ‘10’, ‘11’, ‘12’, ‘13’, ‘14’.

Returns:

Brightness temperature values in [K] at TOA. Shape

according to data resolution of the respective channel.

Return type:

ndarray
