Sentinel-5P

Overview

The Sentinel-5P mission provides daily global atmospheric measurements at a resolution of 3.5km x 7km on most bands.

This dataset represents the global archive of Sentinel-5P Level 2 products, from 2018 to the present, in NetCDF format.

Sentinel-5P data on Azure are maintained by Sinergise.

Sentinel-5P data are currently in preview on Azure; email aiforearthdatasets@microsoft.com to request access.

Storage resources

Container information

Data are stored as NetCDF files in Azure Blob Storage in the West Europe Azure region, in the following blob container:

https://sentinel5euwest.blob.core.windows.net/sentinel-5p

Scene names

Within that container, each scene corresponds to a folder, named according to:

TROPOMI/[product]/[year]/[month]/[day]/[scene_name]

• product is a product identifier, one of:
  • L2__AER_AI: UV aerosol index
  • L2__AER_LH: Aerosol layer height
  • L2__CH4___: Methane (CH₄)
  • L2__CLOUD_: Cloud
  • L2__CO____: Carbon monoxide (CO)
  • L2__HCHO__: Formaldehyde (HCHO)
  • L2__NO2___: Nitrogen dioxide (NO_2</sub)
  • L2__O3____: Ozone (O₃
  • L2__O3_TCL: Tropospheric ozone
  • L2__SO2___: Sulfur dioxide (SO₂)
  • L2__NP_BD3: Cloud from the Suomi NPP mission, band 3
  • L2__NP_BD6: Cloud from the Suomi NPP mission, band 6
  • L2__NP_BD7: Cloud from the Suomi NPP mission, band 7
• year is the four-digit year
• month is the 1-indexed, zero-padded month
• day is the 1-indexed, zero-padded day of month

scene name follows the Sentinel-5P file name convention:

• S5P is the mission indicator (Sentinel-5P)
• CCCC is a file class, one of:
  • NRTI (near-real-time processing)
  • OFFL (offline processing)
  • RPRO (reprocessed) (uncommon)
• L2 indicates level-2 data
• PPPPPPPPPP is a ten-character product identifier, matching the product field above
• yyyymmddThhmmss is the sensing start time for this scene (T is the character ‘T’)
• YYYYMMDDTHHMMSS is the sensing stop time for this scene (T is the character ‘T’)
• oooooo is an absolute orbit number
• cc is a collection number (always 01)
• pppppp is the version number of the toolkit used to produce the L2 product`
• xxxxxxxxxxxxxxx is a processing date and time

Putting that all together, the following is a complete URL to a methane product from Jan 5, 2021:

Image files

Each scene folder contains a single NetCDF file whose name matches the scene name; for example, the above folder contains one file called:

S5P_OFFL_L2__CH4____20210105T001436_20210105T015606_16736_01_010400_20210106T172254.nc

Sample code

A complete Python example of accessing and plotting Sentinel-5P data is available in the accompanying sample notebook.

Region information

Large-scale processing is best performed in the West Europe Azure region, where the images are stored.
