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
