BEAT-II Record: OSIRIS_L2_Aerosol_MART

Fields

The table below gives an overview of possible fields that can be returned from an ingestion of OSIRIS_L2_Aerosol_MART 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
elements_per_profile	int32	[profile]	included
time_per_profile	double	[profile]	included	The time of the profile (in seconds since 2000-01-01 00:00:00)
latitude_per_profile	double	[profile]	included	The center latitude for a profile
longitude_per_profile	double	[profile]	included	The center longitude for a profile
altitude	double	[main]	included	The altitude (in km) for each profile element
aerosol_number_density	double	[main]	included	Aerosol number density (in cm^-3)
aerosol_number_density_error	double	[main]	included	Precision of the aerosol number density (in cm^-3)
solar_zenith_angle	double	[main]	excluded	Solar zengith angle at the tangent point of the measurement. 0 is sun overhead, 90 is sun on the horizon
solar_azimuth_angle	double	[main]	excluded	Solar azimuth angle at the tangent point of the measurement. 0 is due North, 90 is due East, 180 is South and 270 is West

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
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.
time_per_profile_min	time*	Only include elements for which the value is greater than or equal to the provided filter option value
time_per_profile_max	time*	Only include elements for which the value is less than or equal to the provided filter option value
time_per_profile	time*	Only include elements that match the list of given filter option values
latitude_per_profile_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
latitude_per_profile_max	double	Only include elements for which the value is less than or equal to the provided filter option value
latitude_per_profile	double	Only include elements that match the list of given filter option values
longitude_per_profile_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
longitude_per_profile_max	double	Only include elements for which the value is less than or equal to the provided filter option value
longitude_per_profile	double	Only include elements that match the list of given filter option values
altitude_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
altitude_max	double	Only include elements for which the value is less than or equal to the provided filter option value
altitude	double	Only include elements that match the list of given filter option values
aerosol_number_density_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
aerosol_number_density_max	double	Only include elements for which the value is less than or equal to the provided filter option value
aerosol_number_density	double	Only include elements that match the list of given filter option values
aerosol_number_density_error_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
aerosol_number_density_error_max	double	Only include elements for which the value is less than or equal to the provided filter option value
aerosol_number_density_error	double	Only include elements that match the list of given filter option values
solar_zenith_angle_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
solar_zenith_angle_max	double	Only include elements for which the value is less than or equal to the provided filter option value
solar_zenith_angle	double	Only include elements that match the list of given filter option values
solar_azimuth_angle_min	double	Only include elements for which the value is greater than or equal to the provided filter option value
solar_azimuth_angle_max	double	Only include elements for which the value is less than or equal to the provided filter option value
solar_azimuth_angle	double	Only include elements that match the list of given filter option values

^* Time values can be passed as either 'yyyy-mm-dd', 'yyyy-mm-ddThh:mm:ss', 'yyyy-mm-ddThh:mm:ss.uuuuuu' or a floating point value indicating the amount of seconds since 2000-01-01 00:00:00.
