Congratulations👇! An excellent way to ensure long-term impact. Let's discuss next week at #EGW2025 #oneEuroGEO @EuroGEO_eu
📢 New #OPEN EO Landsat data on #CDSE: one of the main objectives of the @REA_research Horizon Europe @EarthMonitorOrg project is producing Analysis-Ready (ARD) and Decision-Relevant (DRD) Data that is open, cloud-optimized and complete, consistent, current and correct (4C-ARCO). In the last 2 years we have put an effort to process the global @UMD_GLAD Landsat ARD 16-day version 2 (doi.org/10.3390/rs1203…) to produce bi-monthly composites for 1997-2024. Thanks to the kind support from @CloudFerro @esa and @landcarbonlab , this data is now available openly and within the Europe's central infrastructure for EO data #CDSE:

This is about 150TB of GeoTIFFs available as 100x100 km tiles (about 18,600 tiles to cover the whole planet) under the CC-BY license. Harmonizing and gap-filling Landsat is not trivial however (doi.org/10.7717/peerj.…): there are still many artifacts in the data, especially winter months in northern hemisphere (>40 degrees latitudes) still contain artifacts in terms of stripes, snow patterns and similar.
How can you use this data? From the bimonthly bands you can derive a diversity of indices (…me-ee-spectral-indices.readthedocs.io/en/latest/list… and indexdatabase.de/db/i.php) and then run time-series analysis to detect long-term trends. Here is an example of how we used Landsat bimonthly product to derive global GPP at 30-m resolution: landcarbonlab.org/insights/globa…
The global GPP is then used as input to soil carbon mapping to detect areas of potential carbon gains / losses: world.soils.app.
We are already working on the OpenGeoHub Landsat 4C-ARCO V2 which will be monthly, 16-bit and should have less artifacts / be more consistent.
