Sentinel-5P L2

About Sentinel-5P Data

Sentinel Hub supports Sentinel-5P level 2 (L2) data products as provided by ESA. General information about the satellite and specifically Level 2 data is available here: Raw bands (Level 1 products) are not available in Sentinel Hub.

Mission Information

The Sentinel-5P (P for precursor) mission aims at providing information and services on air quality and climate between 2017 and at least 2023. With the TROPOMI sensor on board it makes daily global observations of key atmospheric constituents, including ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, methane, formaldehyde as well as cloud and aerosol properties. The mission aims at ensuring data continuity between the retirement of the Envisat satellite and NASA's Aura mission and the launch of Sentinel-5 (source: ESA).

Revisit timeLess than one day.
Spatial coverageGlobal coverage.
Data availabilitySince April 2018.
Common usage/purposeTo provide global information on a multitude of atmospheric trace gases, aerosols and cloud distributions affecting air quality and climate.

* "5.5 x 3.5" means a spatial resolution of 5.5 km in the satellite flight direction and 3.5 km in the perpendicular direction at nadir. Data released before 6 August 2019 had a resolution in the flight direction up to 7 km (see ESA news).

Attribution and Use

EU law grants free access to Copernicus Sentinel Data and Service Information for the purpose of the following use in so far as it is lawful: a) reproduction; b) distribution; c) communication to the public; d) adaptation, modification and combination with other data and information; e) any combination of points a to d.

Accessing Sentinel-5P Data

To access data you need to send a POST request to our process API. The requested data will be returned as the response to your request. Each POST request can be tailored to get you exactly the data you require. To do this requires setting various parameters which depend on the datasource you are querying. This chapter will help you understand the parameters for S5PL2 data. To see examples of such requests go here, and for an overview of all API parameters see the API Reference.

Data type identifier: S5PL2

Use S5PL2 as the value of the parameter in your API requests. This is mandatory and will ensure you get Sentinel-5P L2 data.

Filtering Options

This chapter will explain the object of the S5PL2 process API.


For simple mosaicking, the time range which is requested is clipped to start at most 24 hours before the to date-time. The reason for this is that Sentinel-5P covers the globe in one day therefore longer time ranges are not neccessary. The limitation also improves the responsiveness of Sentinel Hub.


Sets the order of sources from which the output result is mosaicked. If there are multiple sources available for the same time, unless explicitly set otherwise, Sentinel Hub will take the source with the slowest timeliness (i.e. RPRO prefered to OFFL prefered to NRTI).

You can force the timeliness of the requested data. If not set and there are multiple sources available for the same time, Sentinel Hub will take the source with the slowest timeliness (RPRO prefered to OFFL prefered to NRTI). To explicitly set, the options are:

  • NRTI for near realtime,
  • OFFL for offline,
  • RPRO for reprocessing.

Processing Options

This chapter will explain the object of the S5PL2 process API.

upsamplingDefines the interpolation used for processing when the pixel resolution is greater than the source resolution (e.g. 5m/px with a 10m/px source)NEAREST - nearest neighbour interpolation
BILINEAR - bilinear interpolation
BICUBIC - bicubic interpolation
downsamplingAs above except when the resolution is lower.NEAREST - nearest neighbour interpolation
BILINEAR - bilinear interpolation
BICUBIC - bicubic interpolation
minQaSentinel-5P data is flagged with quality values (“qa_value”). minQa is the minimum (inclusive) pixel quality to be displayed in percent.
For example, setting minQa = 75 will only display pixels with qa_value >= 75%
Values between 0 and 100.75 For NO2
50 for other products

Available Bands and Data

Information in this chapter is useful when defining input object in evalscript: any string listed in the column Name can be an element of the input.bands array in your evalscript.

The data values for each band in your custom script are presented in the default units as specified here. In case more than one unit is available for a given band, you may optionally set the value of input.units in your evalscript setup function to one of the options. Doing so will present data in that unit. The Source Format specifies how and with what precision the digital numbers from which the unit is derived are encoded. The Typical Range indicates what values are common for a given band and unit, however outliers can be expected.

Collection Specific Constraints

The raw data is encoded as 32-bit float samples. For scientific usage it is best to set tiff as an output format and sampleType: SampleType.FLOAT32.

Sentinel-5P data can potentially contain many no data pixels which is a consequence of the way it is measured. We therefore suggest using the dataMask band to differentiate between actual zero values and no data.

Catalog API Capabilities

To access Sentinel 5P L2 product metadata you need to send search request to our Catalog API. The requested metadata will be returned as JSON formatted response to your request.
