Search Sentinel-5p products

The following code shows how to search Sentinel-5p products in WASDI


To run this code you need:
  • A running Python 3.x Environment

  • A valid WASDI Account

If this is not clear, you probably need to take a look to the Python Tutorial before.



Assume you have at least one workspace and you configured it in the config.json file

These are different samples of Sentinel-5p Search. The mandatory fields to search are:
  • Mission Type

  • Start Date

  • End Date

  • Product Type

  • Bounding Box

# Create the Bounding Box Object: usually you will take if from the parameters
oBBox = wasdi.getParameter("BBOX", None)

# If it is null we show here how to initialize manually
if oBBox is None:
    oBBox = {"northEast": {}, "southWest": {}}
    oBBox["northEast"]["lat"] = 20.1
    oBBox["northEast"]["lng"] = 44.4
    oBBox["southWest"]["lat"] = 19.3
    oBBox["southWest"]["lng"] = 43.2

# Set Start Date getting the parameter from parameters file, fallbacks to 2023-01-01 if value is not specified
sStartDate = wasdi.getParameter("START_DATE", "2023-01-01")
# Set End Date getting the parameter from parameters file, fallbacks to 2023-01-10 if value is not specified
sEndDate = wasdi.getParameter("END_DATE", "2023-01-10")

# product type: Nitrogen Dioxide (NO2)
sProductType = 'L2__NO2___'

# Start Search S3 Images using the automatic provider selection
aoProductsFoundArray = wasdi.searchEOImages("S5P", sDateFrom=sStartDate, sDateTo=sEndDate,
                                            sProvider="AUTO", oBoundingBox=oBBox)

# The result is an array of Objects. Each Object is a Dictionary.

# Let's see how many products correspond to our query
wasdi.wasdiLog(f'Your query identified {len(aoProductsFoundArray)} products')

# If we have results
if len(aoProductsFoundArray) > 0:
    # as an example, let's print the filename of the first product we found

What it does:

  • Initialize the input variable needed.

  • Start Searching for Sentinel-5p products choosing automatically the provider

  • prints the number of results

  • as an example, prints the filename of the first product found


The developer can decide whatever is needed in the params.json file. If you will use the WASDI User Interface your parameters will be generated automatically by WASDI.


With the WASDI User Interface you can use the renderAsStrings flag to ask WASDI to get all your parameters in String Format. In this case you will be responsible to convert your data in your code


The Bounding Box Format Here Used is the one used by the User Interface when renderAsStrings is missing or false. The Bounding Box format when renderAsStrings: true is “NORTH,WEST,SOUTH,EAST”


The Date is formatted by the User Interface as “YYYY-MM-DD”
