GOME2_L1_sun_reference

Variables

The table below lists the variables that are present in the HARP product that results from an ingestion of GOME2_L1_sun_reference data.

field name	type	dimensions	unit	description
datetime_start	double	{time}	[seconds since 2000-01-01]	start UTC date/time of Sun calibration mode measurement
datetime_stop	double	{time}	[seconds since 2000-01-01]	end UTC date/time of Sun calibration mode measurement
orbit_index	int32			absolute orbit number
wavelength_photon_irradiance	double	{time, spectral}	[count/s/cm2/nm]	solar mean reference spectrum
wavelength	double	{time, spectral}	[nm]	nominal wavelength assignment for each of the detector pixels
index	int32	{time}		zero-based index of the sample within the source product

Ingestion options

The table below lists the available ingestion options for GOME2_L1 products.

option name	legal values	description
band	band-1a, band-1b, band-2a, band-2b, band-3, band-4	only include data from the specified band (‘band-1a’, ‘band-1b’, ‘band-2a’, ‘band-2b’, ‘band-3’, ‘band-4’); by default data from all bands is retrieved
data	transmission, sun, moon, sun_reference	retrieve the measured radiances (default), the transmission spectra (data=transmission), the sun measurement spectra (data=sun), the moon measurement spectra (data=moon) or the sun reference spectrum (data=sun_reference

This definition is only applicable when: data=sun_reference
