BEAT-II Record: HITRAN
Fields
The table below gives an overview of possible fields that can be returned from an ingestion of HITRAN data. The 'default' column indicates whether the specified data item is included in the ingestion by default or not. You can change which data items are ingested by making use of the include and exclude filter options (see below).
| field name | type | dimensions | default | description |
|---|---|---|---|---|
type | string | included | reference to the type of data in this record | |
line_intensity_h2o | double | [main, spectra] | included | Water vapour line intensity for the reference lines |
line_intensity_h2o_unit | string | included | cm^-1/molecules.cm^-2 | |
wavenumber | double | [main, spectra] | included | The wavenumber for each of the reference lines |
wavenumber_unit | string | included | cm^-1 | |
transition_moment | double | [main, spectra] | included | Weighted transition-moment squared |
einstein_a_coefficient | double | [main, spectra] | included | Einstein A-coefficient |
air_broadened_width | double | [main, spectra] | included | Air-broadened width |
self_broadened_width | double | [main, spectra] | included | Self-broadened width |
lower_state_energy | double | [main, spectra] | included | lower-state Energy |
temperature_dependence | double | [main, spectra] | included | Temperature dependence (of air width) |
pressure_shift | double | [main, spectra] | included | Pressure shift |
Ingestion filter options
Ingestion filter options are passed as a ',' or ';' separated string to the ingestion function. Each filter option needs to be formulated as option_name=value[ value value] (some options accept more than one value). For example, if a product has filter options 'altitude_min' and 'time_min' you can provide a filter option string "latitude_min=30,time_min=2003-01-01" to get all measurements at or above 30km and on or after January 1st 2003.
| option name | type | description |
|---|---|---|
product_type | string | BEAT will not be able to automatically recognize this product, so you will have to provide a filter option product_type=HITRAN to let BEAT-II know that the files that you provided are of this type. |
include | string | Provide a space-separated list of field names to ingest additional data items (i.e. fields that are not ingested by default). You can use the special case include=* to indicate that you want to ingest all available data items. |
exclude | string | Provide a space-separated list of field names that you don't want ingested. Mind that the exclude filter is processed after the include filter. |
wavenumber_min | double | Only include data where the wavenumber is greater then or equal to the value provided (in cm^-1) |
wavenumber_max | double | Only include data where the wavenumber is less than or equal to the value provided (in cm^-1) |

Below a description is provided on how each data item in the ingested record was retrieved from the product.
