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 radiance, transmission, sun, moon, sun_reference retrieve the measured radiances, the transmission spectra, the sun measurement spectra, the moon measurement spectra or the sun reference spectrum; by default the measured radiances are retrieved

This definition is only applicable when: data=sun_reference
