What is the mechanism linking the unexpected August 2021 rainfall on Greenland with snow and ice melt on the ice sheet? Researchers from GEUS (Geological Survey of Denmark and Greenland), leading the Pre-Operational Sentinel-3 snow and ice products (SICE) project, highlighted a feedback framework where, before the rain, warm atmospheric rivers triggered melting which exposed darker …
Stratospheric ozone (the “ozone layer”) protects the biosphere from harmful UltraViolet (UV) radiation. Ozone (O3) is expected to recover as a consequence of the Montreal Protocol signed in 1987 and its Amendments regulating the phase-out of ozone-depleting substances (ODS). The stratospheric halogen amount (mainly bromine and chlorine) released by ODSs reached its maximum abundance in …
ESA’s Earth System Data Lab (ESDL) has been providing a virtual lab to access a wide array of Earth observations across space, time, and variables. It consists of two elements: a data cube and an interface to execute a variety of analyses on the data cube. The new recently launched follow-on project, called DeepESDL, …
Combining satellite measurements from Swarm, as well as from the earlier German Champ mission and Danish Ørsted mission, with a computer model of the geodynamo, a new type of magnetic wave, with a 7 year period, and a westward drift at phase speed of 1500km/year, has been mapped at the Earth’s core-mantle boundary. Such Magneto-Coriolis …
SNAP downloads doubled in the last two years, an amazing achievement for the open-access Earth observation analysis tool. Read the full story.
PASS-SWIO, a project funded by ESA (via the Permanent Open Call), aims to establish a sea level monitoring system for Madagascar based on the installation and deployment of a low-cost relocatable tide gauge (Portagauge). Portagauge uses GNSS interferometric reflectometry (GNSS-IR) technology alongside a conventional radar. By combining these measurements with the analysis of satellite altimeter …
Join us during LPS22 in Bonn to learn about EO AFRICA and the latest research results in Africa. LPS22 is the key event in Earth Observation, organised every 3 years by ESA and gathering more than 3000 participants from any part of the world. During the 5-days event, the state of the art of scientific …
Within two years, the Irrigation+ project consortium published 16 peer-reviewed scientific papers which leverage advanced Earth observation algorithms and techniques for irrigation mapping, quantification and detection. An overview of main achievements – taking advantage of the exploitation of Copernicus Sentinel data – is provided in a webstory published today. Read the story. Featured …
Observing and understanding aerosol properties is fundamental for the remote sensing community, yet things get more complicated in cloudy environments. Pixels located in the transition zone between pure cloud and pure aerosol are often discarded by both aerosol and cloud algorithms, despite being essential for studying aerosol–cloud interactions, which still represent the largest source of …
A high level of innovation in algorithm development and methodological approach is the key feature of the activities performed during the ESA S5P+Innovation AOD/BRDF project. Aerosol Optical Depth (AOD) is the single most comprehensive variable for the remote assessment of the aerosol load in the atmosphere. Atmospheric aerosols, such as aerosols from the burning of …
