SCIAMACHY_L1c_sun_reference
Variables
The table below lists the variables that are present in the HARP product that results from an ingestion of SCIAMACHY_L1c_sun_reference data.
| field name | type | dimensions | unit | description |
|---|---|---|---|---|
| wavelength_photon_irradiance | double | {time, spectral} | [(count/s/cm2/nm)] | wavelength photon irradiance of each spectrum measurement |
| wavelength_photon_irradiance_uncertainty | double | {time, spectral} | [(count/s/cm2/nm)] | error in the wavelength photon radiance of each spectrum measurement |
| 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 SCIAMACHY_L1c products.
| option name | legal values | description |
|---|---|---|
| data | nadir, limb, occultation, sun_reference | retrieve the nadir, limb, occultation or sun_reference spectra; by default the nadir spectra are retrieved |
This definition is only applicable when: data=sun_reference
Mapping description
The table below details where and how each variable was retrieved from the input product.
| field name | mapping description | |
|---|---|---|
| wavelength_photon_irradiance | path | /sun_reference[]/mean_ref_spec[], /sun_reference[]/sun_spect_id |
| description | only the first calibrated diffuser sun spectrum (i.e. whose sun_spect_id starts with ‘D’) is ingested | |
| wavelength_photon_irradiance_uncertainty | path | /sun_reference[]/rad_pre_mean_sun_ref_spec[], /sun_reference[]/sun_spect_id |
| description | only the first calibrated diffuser sun spectrum (i.e. whose sun_spect_id starts with ‘D’) is ingested | |
| wavelength | path | /sun_reference[]/wvlen_sun_meas[], /sun_reference[]/sun_spect_id |
| description | only the first calibrated diffuser sun spectrum (i.e. whose sun_spect_id starts with ‘D’) is ingested | |
