The Data Portal is recovering from some unexpected issues with the underlying infrastructure used for data storage. We are working on incrementally reviving all datasets hosted on the portal. Return to operations with all hosted datasets online is early August. Any updates to this timeline will be posted on the site banner. We apologize for the inconvenience. If you have any questions or concerns, please contact support@nas.nasa.gov
AGHSD Data Portal
AGHSD (NASA Ames Global Hyperspectral Synthetic Data)
Welcome to the AGHSD Data Portal
This data is top-of-atmosphere (TOA) reflectance data in the spectral range from 380 nm to 2500 nm at a 10 nm resolution generated based on global MODIS observations and an AVIRIS hyperspectral library with a linear unmixing algorithm.
You can use this portal to download data from the AGHSD Portal.
