BEAT-II Record: TEMIS_L3_NO2

Fields

The table below gives an overview of possible fields that can be returned from an ingestion of TEMIS_L3_NO2 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
time	double	[main]	included	The time of the data fields (in seconds since 2000-01-01 00:00:00)
grid_latitude	double	[latitude]	included	Mid-point latitude values for the grid cells
grid_longitude	double	[longitude]	included	Mid-point longitude values for the grid cells
no2_column_tropospheric_grid	double	[main, latitude, longitude]	included	Tropospheric NO2 column density
no2_column_tropospheric_grid_unit	string		included	molec/cm^2

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=TEMIS_L3_NO2 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.
time_min	time*	Only include elements for which the value is greater than or equal to the provided filter option value
time_max	time*	Only include elements for which the value is less than or equal to the provided filter option value
time	time*	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.

Mapping description

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

field name	mapping description
grid_latitude	description	A uniform increasing sequence on the interval (-90,90)
grid_longitude	description	A uniform increasing sequence on the interval (-180,180)
no2_column_tropospheric_grid_unit	description	Will be set to "molec/cm^2"
