• We are adding the most recent ICESat-2 data to the web app, in addition to performing maintenance on the OpenAltimetry database.  As a result, there may be intermittent, temporary issues accessing certain data in OA.  Additionally, the latest date with data will shift over time as new data are added.  The most recent date with data availability will vary by data set.  This issue will be temporary and short-lived.

What is OpenAltimetry?

NASA’s OpenAltimetry (OA) is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from ICESat-2 and ICESat satellite mission altimetry data. With OA, users can explore how different types of surface heights have changed across the Earth over time, and all you need is a web browser.
