Rolling with a solar storm: How ICESat-2 got back on track

In May 2024, our planet experienced one of the strongest solar storms in decades. The most visible (and fun) consequence of the solar storm was a proliferation of auroras. But solar storms pose risks to satellites, including NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) which saw its normal operations interrupted.

This plot shows global snow class climatology, with no snow in red, ephemeral snow in orange, transitional snow in yellow, seasonal snow in green, and perennial snow in blue.

Using MODIS data to visualize the presence or absence of snow on a global scale

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) manages a range of MODIS data, making a suite of snow cover and sea ice data products freely accessible to the public. These data can be used to investigate how snow and ice cover have changed over time, to study Earth’s energy balance, and to feed global and polar climate models. Recently, the NSIDC DAAC published a new MODIS data set, MODIS/Terra Global Annual 0.01Deg CMG Snow Cover Climatology, Version 1. This data set focuses on global snow cover climatology from 2001 to 2023 using data from the Terra satellite and presents information using global maps.

Quenching the arid West with record snowfall: The tools behind snow data

The 2023 winter brought record snowfall to California and other parts of the western United States, but unlike rain, snowfall is much more nuanced in its properties. Getting accurate snow depth data over a wide area is not easy. Read more about the challenges of garnering snow data and the tools behind snow data.

OpenAltimetry elevates data access

NASA’s OpenAltimetry tool allows experienced and new users alike to quickly find and download elevation data through a web browser without the need for costly software or hefty computational resources.

NSIDC at AGU Annual Meeting 2023

Several representatives from NSIDC will be attending the American Geophysical Union (AGU) Annual Meeting 2023 to share their expertise and connect with Earth Science experts. We've compiled a list of all sessions in which NSIDC staff are involved, including presentations, posters, workshops and other discussions.

Glaciers, or accumulations of ice and snow that slowly flow over land, are disappearing as the planet heats up because of climate change. In this image, melt from a glacier extending from the Juneau Icefield in Alaska forms braided streams as the glacier retreats. The Global Land Ice Measurements from Space initiative is working to document disappearing glaciers.

Showcasing the death of the world’s glaciers

Melting glaciers and ice sheets are already the biggest contributors to global sea level rise. Yet, of the approximately 200,000 glaciers in the world currently, no database exists to identify which glaciers have disappeared, and when. The Global Land Ice Measurements from Space (GLIMS) initiative, an international project designed to monitor the world's glaciers primarily using data from optical satellite instruments, aims to change that.
