21 March, 2022 - International Forest Day
To draw attention to such an important event, the European Space Agency gathered opinions by scientists of Gamma Remote Sensing and Wageningen University that monitor forests with Sentinel data. A Sentinel Success Story highlights the importance of Sentinel-1 global and repeated observations, a breakthrough primarily in tropical regions where cloud cover does not allow for frequent observations with optical sensors.

13 September, 2021 - Global seasonal interferometric Sentinel-1 coherence and backscatter data set
In a NASA/JPL-funded project, GAMMA Remote Sensing AG and Earth Big Data LLC have produced a global data set of Sentinel-1 coherence as well as backscatter. The data set, produced from 205000 Sentinel-1 Interferometric Wide Swath mode SLCs acquired between December 2019 and November 2020, comprises seasonal mosaics of the interferometric repeat pass coherence at repeat intervals of 6 to 48 days as well as backscatter at a spatial resolution of 3 arcseconds. The data can now be downloaded free of charge via the AWS Registry of Open Data.
The project results have been presented at the 2021 ESA Fringe Workshop.
11 August, 2021 - New paper on the global above-ground biomass pool for 2010
The terrestrial forest carbon pool is poorly quantified, in particular in regions with low forest inventory capacity. By combining multiple satellite observations of synthetic aperture radar (SAR) backscatter around the year 2010, we generated a global, spatially explicit dataset of above-ground live biomass (AGB; dry mass) stored in forests with a spatial resolution of 1 ha...

17 March, 2021 - Maps to improve forest biomass estimates, ESA Press Release
New maps, generated by a research team working as part of ESA’s Climate Change Initiative provide a global view of above ground biomass distribution. GAMMA is responsible for the mapping algorithms, system development and map production.
The full press release from ESA can be found at this link.

01 October, 2019 - New 3-years EUROSTARS project started!
GAMMA, SATIM (www.satim.pl) and ICEYE Polska started the 3-years EUROSTARS E!113220 Project RAMON: INNOVATIVE RADAR-BASED SERVICE FOR NEAR REAL-TIME LANDSLIDES MONITORING. We design, develop and test an innovative radar-based landslides monitoring service to support different phases of the landslide risk management. The service combines existing, established elements as landslide velocity maps derived from stacks of satellite SAR data using Persistent Scatterer Interferometry with new near-real-time monitoring elements, as urgently required during crisis situations, made possible using a novel microsatellite constellation and terrestrial radars.
20 August, 2019 - UAV-borne and car-borne repeat-pass radar interferometry with our novel compact GAMMA L-band SAR
In fall 2018 and winter 2019, we have conducted synthetic aperture radar (SAR) campaigns demonstrating the feasibility of measuring surface displacements by means of UAV-borne and car-borne repeat-pass interferometry using the novel GAMMA L-band SAR system, a compact FMCW SAR system (weight: 7.65 kg) with up to 4 simultaneous receive channels and one or two (alternating) transmit channels supporting various interferometric as well as fully-polarimetric acquisition modes. The VTOL UAV used for the airborne SAR acquisitions is the Scout B1-100 developed and operated by Aeroscout GmbH. The car-borne SAR project is in collaboration with ETH Zurich, supported by Innosuisse - Swiss Innovation Agency. Please check the documents below for more information.
