May 2026 EARTHDATA DISCOVERY Open Access for Open Science

Satellites and Models Can Fill the Gaps in Watershed Data           NASA data and modeling are helping farmers and land managers better understand runoff, sediment, and water quality in watersheds with limited ground-based monitoring.

Kicking off Development of New Earth Observation Solutions The biennial survey by the Satellite Needs Working Group to assess Earth observation needs opens soon. Learn more about the survey and read about the progress that has been made on previously identified solutions.                   Webinars & Events

Navigating NASA Earthdata Pathfinders May 27, 2026     Join us for an informative walkthrough of data pathfinders on the Earthdata website. This short webinar will showcase the convenience they provide for finding news, datasets, research tools, and other content related to specific scientific topics.                     Introduction to Thermal Remote Sensing and Applications in Urban Heat Island Mapping May 26 and June 2, 2026 This two-part Applied Remote Sensing Training Program (ARSET) training will introduce thermal infrared remote sensing theory and how it can be applied to map urban heat vulnerability using data from the ECOSTRESS mission. Participants will gain practical skills in R and JavaScript-based thermal data analysis and in downscaling workflows in Google Earth Engine.               May 21 and 28, 2026 Estimating Biomass and Change with GEDI and the OBIWAN API (available in English and Spanish)           June 18, 23, and 25, 2026 Monitoring and Predicting Floods Using Earth Observations for Planning and Preparedness           July 28-31, 2026 Earth Science Information Partners 2026 July Meeting           Recorded on April 22, 2026 Downloading Data from the NASA Earthdata Cloud Using the earthaccess Python Library           Recorded on April 29, 2026 Laser Altimetry Applications for a Changing World: Measuring Snow Depth with ICESat-2                     Learning Resources           Why Sea Surface Salinity Matters for Arctic Sea Ice Learn about the important role Arctic river discharge plays in controlling early fall sea ice formation in the Beaufort Sea.           Customize HLS RGB Imagery Composites in Worldview This tutorial demonstrates how to create your own Harmonized Landsat Sentinel 2 (HLS) image composite or select from a preset list.           Open Science Essentials NASA offers a freely accessible training course designed for learners who are seeking an overview of open science concepts. The course introduces the principles, practices, and tools necessary to conduct open science and covers key topics such as open data, open peer review, and collaborative research practices.                     Data Alerts           GNSS RO Data Products Released in a Common CF Compliant Format           CALIPSO Final Data Products           NOAA-21 VIIRS Version 2 BRDF, NBAR, and Albedo Products Released           VIIRS Version 2 Surface Reflectance and Vegetation Products Available in AppEEARS           ClimFiSP Level 3, Version 2, Monthly Collections Released           NASA's LAADS DAAC Releases MODIS-VIIRS Cloud Mask Version 2.0 Collection Products           ECOSTRESS Version 3 Level 2 Data Products Released           ArcGIS Image Service for TEMPO Ozone Profile V04, 0-2 km Column Ozone Data Release Announcement                   Track Data Outages and New Dataset Releases ➞                     Worldview Images of the Week           Fall Colors in Chile Data from the Harmonized Landsat and Sentinel-2 product and Worldview captured the change of seasons across the southern Andes.           Late Spring Storm Brings Snow to Colorado and Wyoming Snow cover from a recent storm is visualized using false-color Terra MODIS imagery and a snow cover index.           A Different View of Lake Bangweulu and Wetlands, Zambia A false-color corrected reflectance image from the MODIS instrument aboard the Terra platform shows Zambia’s Lake Bangweulu and its wetlands — an area designated as wetlands of international importance by the RAMSAR Convention.                 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.
