Landsat DEM source data now available for download

These DEM sources have been modified for use in Collection 2 Level-1 data processing. Void-filling techniques were used where persistent gaps were found in the elevation data, and improvements to the vertical accuracy were realized by differencing accuracies of other elevation datasets to the newer Collection 2 DEM.

Aeolus enhances volcanic ash for aviation safety

🌋 Forecasting volcanic ash in the atmosphere is crucial for aviation, as ash can interfere with aircraft navigational instruments and can even damage engine parts.

🌋 In the new paper, it was found that the predictions of the volcanic ash plume position shifted considerably when Aeolus data were incorporated. According to the PANGEA observations, forecasts that drew on Aeolus data displayed a considerable improvement in the simulated shape and position of the ash cloud.

EOSDA Gets First Ready-to-Use Images From Its EOS SAT-1 Satellite

🛰️ EOS SAT is a constellation comprising seven small optical satellites designed to support the implementation of sustainable agriculture methods and forestland monitoring with high-quality data and analysis.

🛰️ After reaching full operation by 2025, the constellation will cover up to 100% of countries with the largest areas of farmlands and forestlands, amounting to 98.5% of such lands across the globe.
