How is Sentinel 5P L2 converted to Earth Engine?
To make it possible to ingest the data into Earth Engine, each Sentinel 5P L2 product is converted to L3, keeping a single grid per orbit (that is, no aggregation across products is performed). Source products spanning the antimeridian are ingested as two Earth Engine assets, with suffixes _1 and _2.
How is Sentinel 5P Level 2 data binned?
The original Sentinel 5P Level 2 (L2) data is binned by time, not by latitude/longitude. To make it possible to ingest the data into Earth Engine, each Sentinel 5P L2 product is converted to L3, keeping a single grid per orbit (that is, no aggregation across products is performed).
How big is the image in Google Earth Engine?
The smallest jagged edges visible at the mask reflect the 1.1 km pixel resolution of the images stored in Earth Engine (that is, I’ve zoomed in past the resolution of the image). The larger solid color rectangles reflect the resolution of the original sensor data — which you can see falls onto several different grids with different aspect ratios.
What does the Sentinel-5 Precursor mission instrument do?
The Sentinel-5 Precursor mission instrument collects data useful for assessing air quality.
When is the filter date for Sentinel 5P?
We selected the COPERNICUS/S5P/NRTI/L3_NO2 layer – this provides the Sentinel-5P NRTI NO2: Near Real-Time Nitrogen Dioxide measurements. The filter date allows us to only retrieve those measurements taken during the preferred time window – in this case May 2020.
What can I do with Google Earth Engine?
We wanted to experiment with the fantastic Google Earth Engine tool, which allows easy access to petabytes of satellite imagery, current and historic.
What is the purpose of the Sentinel-5 satellite?
Sentinel-5 Precursor is a satellite launched on 13 October 2017 by the European Space Agency to monitor air pollution. The onboard sensor is frequently referred to as Tropomi (TROPOspheric Monitoring Instrument). All of the S5P datasets, except CH 4, have two versions: Near Real-Time (NRTI) and Offline (OFFL).
What is the use of the Copernicus Sentinel data?
The use of Sentinel data is governed by the Copernicus Sentinel Data Terms and Conditions. Important: Earth Engine is a platform for petabyte-scale scientific analysis and visualization of geospatial datasets, both for public benefit and for business and government users.
