February 2025 EARTHDATA DISCOVERY Open Access for Open Science

Meeting the Demand for Data on Urban Areas           NASA released 12 new datasets that demonstrate how the synthesis of Earth science and socioeconomic data can help decision-makers address real-world concerns in urban populations, which are projected to increase by 2.5 billion people by 2050.                   Use NASA’s POPGRID Viewer data tool to explore population counts and settlement mapping from leading global data sources. ➞                       Articles

NASA Begins Final ASTER Data Processing Campaign The final processing of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data will make its entire archive—4.5 million scenes for each of ASTER’s 11 data products—freely available and easily accessible in the Earthdata Cloud.           COWVR and TEMPEST V10 Datasets Available in First Public Release The V10 Compact Ocean Wind Vector Radiometer (COWVR) and Temporal Experiment for Storms and Tropical Systems (TEMPEST) datasets are now available. They provide co-located wind vector measurements and integrated water measurements at the air-sea interface, which are immensely beneficial for users in weather forecasting and climate research.           The Remarkable Derecho of July 15, 2024 An unusual derecho tore through the Midwest in July 2024, targeting the Chicago area with torrential rains and numerous tornadoes. NASA’s Goddard Earth Sciences Data and Information Services Center (GES DISC) discussed this event in two Data in Action articles, “The Remarkable Derecho of July 15, 2024”, and “The Remarkable Derecho of July 15, 2024: Part II”.           Rising Risks of Sliding Slopes in High Mountain Asia A new study warns of increasing landslide hazards in High Mountain Asia due to rising industrial emissions. Researchers created the High Mountain Asia Daily 5km Landslide Hazard Indicator, now available via NASA’s National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), to aid in risk monitoring and mitigation.           Observations of Unusual Lake Effect Snow In January 2025, areas of New York recorded more than 70 inches of snow thanks to a narrow band of lake effect snow that formed over Oswego and Oneida counties. Snow depth data generated hourly by the North American Land Data Assimilation System (NLDAS) provides insight into why this event was unexpected, even in a region known for lake effect snow.           Happy Valentine's Day from Earthdata For Valentine's Day, we created Earth-themed digital cards featuring the Harmonized Landsat and Sentinel-2 (HLS) project, Worldview, Twin Blue Marbles, and more.

NASA CSDA Program Vendor Focus—Airbus February 19, 2025           NASA’s longstanding collaboration with Airbus, a Commercial Satellite Data Acquisition (CSDA) program vendor, now includes providing the NASA community with optical and Synthetic Aperture Radar (SAR) products and services, including elevation data and ground control points.                     Calculating Spectral Indices for Land and Aquatic Applications Using QGIS February 27, 2025 This NASA Applied Remote Sensing Training Program (ARSET) course will provide an overview of spectral indices for land and aquatic applications as they are calculated with a QGIS platform. Specifically, this training will begin with an introduction to the Normalized Difference Vegetation Index (NDVI), along with its calculation, uses, and applications in diverse thematic areas (agriculture, disasters, etc.). This course is also available in Spanish.               Laser Altimetry Applications for a Changing World: Working with ICESat-2 Land and Vegetation Height Data Recorded on February 12, 2025 NASA's Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) was launched in September 2018 to measure the heights of all surfaces across the globe, including land ice, sea ice, oceans, water, and vegetation. In this webinar, learn about the ICESat-2 Land and Vegetation Height data product and its derived continental scale canopy model, and view a demo of the SlideRule Earth web service, which provides high-performance, on-demand science data processing of ICESat-2 and other relevant geospatial data.               Examining Hurricane Milton’s Milestones with NASA's GES DISC Datasets Recorded on January 29, 2025 Datasets provided by NASA’s Goddard Earth Sciences Data and Information Services Center (GES DISC) enable users to investigate the factors that made Hurricane Milton a remarkable, record-setting hurricane. Learn how to access and use these datasets and see how a Python Jupyter Notebook demonstrates data access and map creation using the earthaccess Python library.               NASA CSDA Program Vendor Focus—Capella Space Recorded on January 22, 2025 The Commercial Satellite Data Acquisition (CSDA) program vendor Capella Space provides NASA with high-resolution synthetic aperture radar (SAR) products. View the recording of this Earthdata webinar to learn more about how to discover, access, and work with these data.                         New Data, Tutorials, & Resources           New NASA Earth Science Data NASA’s archive of unrestricted data continues to grow. Read summaries of the latest data products, services, and tools released over the past month.           Jupyter Notebook GitHub Repository Offers Tips and Scripts for Using NASA’s Atmospheric Data NASA’s Atmospheric Science Data Center (ASDC) GitHub hosts tutorials, code, and guides to help Earth science data users address air quality and other environmental challenges.           Help Hub for Ocean Color Learning Resources The Help Hub hosted by NASA's Ocean Biology Distributed Active Archive Center (OB.DAAC) has been updated with new learning resources for processing ocean color satellite data, working with Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) data, and more.           ARSET NASA’s Applied Remote Sensing Training (ARSET) program offers online and in-person trainings for beginners and advanced practitioners alike. Trainings cover a range of datasets, web portals, and analysis tools and their application to air quality, agriculture, disasters, land, and water resource management.                   Worldview Images of the Week           Tropical Cyclone Zelia approaches Western Australia Imagery of Tropical Cyclone Zelia, acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS), shows the Category 5 storm approaching the Pilbara region of Western Australia.           New Orleans and Lake Pontchartrain Before the Super Bowl View an interactive true-color reflectance image of Lake Pontchartrain and New Orleans—the city that recently hosted Super Bowl LIX.           Rare Snowfall Across Southern U.S. This image, captured by the Visible Infrared Imaging Radiometer Suite (VIIRS), is overlaid with Worldview’s snow cover (normalized difference snow index (NDSI) layer to show rare snowfall across the southern U.S. on January 22, 2025.           The Palisades and Eaton Fires, Los Angeles, California View satellite imagery of Southern California before and after the devastation caused by the Palisades and Eaton wildfires.           Iceberg A23A Moving Toward South Georgia Island, Antarctica View an animation showing a series of true-color corrected reflectance images from the Moderate Resolution Imaging Spectroradiometer (MODIS).                 NASA's Earth Science Data Systems (ESDS) Program oversees the life cycle of NASA’s Earth science data and seeks to maximize the scientific return from missions and experiments.
