The open-source model will serve as the basis for future forest, crop and climate change-monitoring AI. NASA estimates that its Earth science missions will generate around a quarter million terabytes of data in 2024 alone. In order for climate scientists and the research community efficiently dig through these reams of raw satellite data, IBM, HuggingFace and NASA have collaborated to build an open-source geospatial foundation model that will serve as the basis for a new class of climate and Earth science AIs that can track deforestation, predict crop yields and rack greenhouse gas emissions. For this project, IBM leveraged its recently-released Watsonx.ai to serve as the foundational model using a year’s worth of NASA’s Harmonized Landsat Sentinel-2 satellite data (HLS). That data is collected by the ESA’s pair of Sentinel-2 satellites, which are built to acquire high resolution optical imagery over land and coastal regions in 13 spectral bands. For it’s part, HuggingFace is hosting the model on its open-source AI platform. According to IBM, by fine-tuning the model on “labeled data for flood and burn scar mapping,” the team was able to improve the model's performance 15 percent over the current state of the art using half as much data. "The essential role of open-source technologies to accelerate critical areas of discovery such as climate change has never been clearer,” Sriram Raghavan, VP of IBM Research AI, said in a press release. “By combining IBM’s foundation model efforts aimed at creating flexible, reusable AI systems with NASA’s repository of Earth-satellite data, and making it available on the leading open-source AI platform, Hugging Face, we can leverage the power of collaboration to implement faster and more impactful solutions that will improve our planet.” source: engadget

Qualcomm Technologies and Xiaomi have verified meter-level positioning in the Xiaomi 12T Pro powered by the Snapdragon 8+ Gen 1 mobile platform, in Germany. Accuracy verification tests, including driving tests, were conducted by Qualcomm Technologies, Xiaomi, and Trimble in various scenarios such as open-sky rural roads and urban highways. The companies’ solutions demonstrated meter-level positioning variance at a 95% confidence level. This level of accuracy in a commercial smartphone is enabled through Qualcomm meter-level positioning for mobile in combination with Trimble RTX correction services. When integrated with Snapdragon mobile platforms, Trimble RTX enhances the phone’s positioning capabilities. Meter-level positioning accuracy can improve smartphone user experience in several scenarios, including mapping, driving, and other mobile applications. It enables greater accuracy when using ridesharing applications to identify pick-up locations for both driver and rider, fitness applications to track users’ movements, and in-vehicle real-time navigation applications for increased lane-level accuracy with greater map details and more accurate directions.

The Aeolus mission is coming to a close on 30 April 2023 with a series of end life activities after achieving many significant accomplishments. Launched in 2018, the mission’s main goal was to measure the Earth’s wind patterns and improve our understanding of how they affect the planet’s climate. That ESA’s wind mission had outlived its predicted lifetime of three years by over 18 months. The best course of action to wind down Aeolus was to carefully re-enter the satellite back to Earth. The finishing touches to the end-of-life schedule will be made in a span of numerous weeks. Innovating Wind Measurement across Earth Using state-of-the-art laser technology, Aeolus was able to measure the wind speeds and direction from space with incredible precision. These measurements were used to create detailed maps of global wind patterns and improve weather forecasting models. In addition to its primary mission, Aeolus also made important contributions to other areas of Earth observation. For example, it provided valuable data on air pollution and dust transport across the globe. As the Aeolus mission winds down, scientists are already looking ahead to future missions that can build on its successes. This includes plans for new Earth observation missions that will focus on other key environmental factors such as ocean currents, land use, and the carbon cycle. Aeolus Mission Manager, Tommaso Parrinello was grateful to all the ESA and industry colleagues who developed and operated the mission. Improvement in Weather Forecasts Aeolus carried ALADIN, an instrument that is Europe’s most sophisticated Doppler wind lidar flown in space. A laser inbuilt the instrument fires pulses of ultraviolet light towards Earth’s atmosphere, which is received by a light detecting receiver that scatters it back from air and water molecules like aerosols and dust. With that measurement one can check the speed of the wind. Over its extended lifetime, ALADIN has beamed down over seven billion laser pulses orbiting Earth 16 times a day and covering the entire globe once a week. Aeolus data are used by major weather forecasting services worldwide, including the European Centre for Medium-Range Weather Forecasts (ECMWF), Météo-France, the UK Met Office, Germany’s Deutscher Wetterdienst (DWD), and India’s National Centre for Medium Range Weather Forecasting (NCMRWF). Since ECMWF started assimilating Aeolus data in 2020 the satellite has become the highest impact-per-observation instruments in existence. It is mainly due to Aeolus’ capacity to measure winds where data is scarce. When planes were grounded during the lockdowns imposed due to the COVID pandemic, Aeolus was able to contribute missing data to plug the gap in weather forecasts. ESA’s Director of Earth Observation Programme, Simonetta Cheli said that the Aeolus mission has been a triumph of European innovation, collaboration and technical excellence, and is an example of how ESA’s Earth Explorers perform beyond expectations, and is a shining light for our Future EO Programme. Its impacts will live long beyond its lifetime in space, paving the way for future operational missions such as Aeolus-2. Despite the mission’s impending end, the data collected by Aeolus will continue to be used by scientists around the world for years ahead in the future. This legacy is a testament to the mission’s trailblazing spirit and its important role in advancing our understanding of the Earth’s climate.

The WMO State of the Global Climate report 2022 focuses on key climate indicators – greenhouse gases, temperatures, sea level rise, ocean heat and acidification, sea ice and glaciers. It also highlights the impacts of climate change and extreme weather. Drought, floods and heatwaves affect large parts of the world and the costs are rising Global mean temperatures for the past 8 years have been the highest on record Sea level and ocean heat are at record levels – and this trend will continue for many centuries Antarctic sea ice falls to lowest extent on record Europe shatters records for glacier melt From mountain peaks to ocean depths, climate change continued its advance in 2022. Droughts, floods and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record and the melting of some European glaciers was, literally, off the charts. The State of the Global Climate 2022 shows the planetary scale changes on land, in the ocean and in the atmosphere caused by record levels of heat-trapping greenhouse gases. For global temperature, 2015-2022 were the eight warmest on record despite the cooling impact of a La Niña event for the past three years. Melting of glaciers and sea level rise - which again reached record levels in 2022 - will continue for up to thousands of years. links: State of the Global Climate in 2022 | World Meteorological Organization (wmo.int)

Several digital elevation model (DEM) sources are used in the processing of Landsat Collection 2 Level-1 products. These sources are based on specific geographic regions and contribute to improved vertical accuracy in Collection 2 when compared to data processed in the past. Together, these sources are all known as the Landsat Collection 2 DEM. These DEM sources have been modified for use in Collection 2 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. The following DEM sources are now available for download from EarthExplorer, listed under the Collection 2 section on the Data Set tab: Global Land Survey (GLS) — Various specific elevation inputs collectively make up the Global Land Surveys (GLS) DEM. Each input is based on the spatial region for which it is appropriate. Radarsat Antarctic Mapping Project (RAMP) — The Radarsat Antarctic Mapping Project (RAMP) is a high-resolution DEM that combines topographic data from a variety of sources to provide consistent coverage of all of Antarctica. Gravity for Earth, Ocean and Ice Dynamics (GEOID) Model — While not an actual elevation dataset, the geoid model provides necessary offsets to adjust the elevations of the GLS DEM from its original Earth Gravitational Model 96 (EGM96) to the World Geodetic System 84 (WGS84) ellipsoid. This is necessary so the GLS DEM can be correctly used by the Landsat processing systems software and algorithms. Please visit Landsat Collection 2 Digital Elevation Model to learn more about these DEM source products, and contact USGS Customer Services with any questions. links: Landsat Collection 2 DEM Source Products Available | U.S. Geological Survey (usgs.gov)
