S5P-PAL Data Portal

This is the dissemination site for data products generated by Sentinel 5P processors running in S5P-PAL.

Most data products published on this portal are pre-operational products. This means that these products may get updated at any point without advance notice and long term availability is also not guaranteed. In case of an update, a description of the changes between the different processor versions generating the products will however be included on the product specific information pages.
As a general disclaimer, using any of these products for operational purposes is at your own risk.


The following products are currently made available publicly via this portal:

Discovery and access

Product file discovery and access is provided by S5P-PAL in the form of web services that implement the SpatioTemporal Asset Catalog (STAC) open standard. These endpoints can be accessed programmatically.

You can also use public STAC browsers, such as for example the Radiant Earth STAC browser, to view the S5P-PAL products interactively through a more convenient graphical Interactive Product Browser.
