• 2. Discover the data: TROPOMI Onboard Sentinel 5P

    This section provides you with an overview of Sentinel 5P - how you may access the data. In this course we will focus on Absorbing Aerosol Index (AAI) and CO TROPOMI S5P data. However, also other TROPOMI parameters, such as NO2 and HCHO can be accessed  and visualised using the instructions below. 

    Sources for browsing S5P images without downloading the data

    Sentinel Hub EO Browser

    1. With  Sentinel Hub EO Browser you can quickly visualize different Sentinel data, including Sentinel 5P. Registration (which is free) is needed to be able to use all options in the EO browser. Registration can be done by selecting first "Login" from the Hub web page, and then "Sign Up" in the new pop-up window.

    2. After login, by checking the box "Sentinel 5P" (you might uncheck the other boxes) a list of Sentinel 5P parameters appear that you can visualize. By selecting the time period from the calendar you can browse the images.

    Near Real Time and Archived Absorbing Aerosol Index from SACS

    The Support to Aviation Control Service (SACS) focuses on the timely delivery of SO2 and aerosol data derived from different satellite instruments to assess possible impact of volcanic eruptions on air traffic control and public safety. Even though the focus of the service is on volcanic eruptions, Absorbing Aerosol Index maps can give useful information on smoke emissions and transport from fires as well. In SACS AAI is available from several different instruments, including TROPOMI. 


    From SACS service you can get the AAI maps from
    1. "Today", which shows the AAI observations from today only
    2. "NRT", which shows the AAI from the past 24 hours, i.e. it is a composite of  observations from today and yesterday.  
    3. "Archive", which shows observations for a specific day that you can select from the calendar. 

    In this section you can find basic information on TROPOMI atmospheric observations relevant for fire monitoring.

    In this section you can find basic information on Google Earth Engine and TROPOMI S5P data. 

      OPTIONAL: How to register to Google Earth Engine (GEE)Page

    In this section you will learn how to register as a user to Google Earth Engine. This is needed in order to use the satellite data.
