The NASA NSIDC Distributed Active Archive Center has updated two Making Earth System Data Records for Use in Research Environments (MEaSUREs) data sets related to the grounding line and grounding zone of the Antarctic Ice Sheet. bit.ly/4cUyrCP

Firnspiegel, or firn mirror, is a thin, shiny sheet of ice formed on the snow surface by rapid refreezing of solar-heated snow or firn, usually at high elevations during spring. Check out more fun cryopsheric terms in the NSIDC glossary. nsidc.org/learn/cryosphe…

NSIDC researchers have established a new standard for air-sea ice observations in the Arctic, representing a significant step towards improving sea ice prediction models by incorporating surface energy measurements from the year-long MOSAiC expedition. bit.ly/3Qv2ucN

The NASA NSIDC Distributed Active Archive Center (DAAC) has released the Ice, Cloud and Elevation Satellite (ICESat)/ICESat-2 Traverse: Monthly GPS Surface Elevation Data at Summit Station, Greenland data set. doi.org/10.5067/UNBV80…

Happy Earth Day! See how sea ice and glaciers respond to climate change with NSIDC data in Google Earth. nsidc.org/data/google_ea…

NASA NSIDC DAAC helps users adapt to science data in the Earthdata Cloud. Tomorrow, April 22 (11:00–11:15 a.m. MDT), a webinar will demonstrate how to use the earthaccess Python library to authenticate, search, & download data in just a few lines of code. go.nasa.gov/4mJnpEY

Pakistan’s Baltoro Glacier is one of the longest glaciers beyond the poles, stretching 63 km (39 miles). It feeds critical meltwater into the Indus River. Marcel Rueedi snapped the photo in 1983. See more from NOAA@NSIDC’s Glacier Photograph Collection. bit.ly/3NcHZxk

In a drunken forest, trees lean in multiple directions, resembling a crowd that has over imbibed. As frozen soil—known as permafrost—thaws, tree roots loosen, causing trees to tilt and heave. Learn more from the NSIDC Cryosphere Glossary: nsidc.org/learn/cryosphe…

Want to see how glaciers are faring in High Mountain Asia? Or anywhere else? Check out the Global Land Ice Measurements from Space (GLIMS) Viewer, available from the NASA NSIDC Distributed Active Archive Center: glims.org/maps/glims

earthaccess is a Python library developed by NASA Distributed Active Archive Centers (DAACs), including NSIDC DAAC, designed to simplify searching, downloading, and streaming NASA Earth science data. bit.ly/3OLOSZY

From April 8 to 15, Arctic sea ice extent dropped about 380,000 sq km, equivalent in size to Montana. Keep track of Arctic and Antarctic sea ice extent with NSIDC's Charctic graph. bit.ly/4rWyQKH

From 2007 to 2022, renowned photographer James Balog documented glacial change around the world through a project called the Extreme Ice Survey. One and a half million images showcasing climate change in real time are now stored and managed at NSIDC. nsidc.org/data/nsidc-078…

You can access data from NASA Visible Infrared Imaging Radiometer Suite (VIIRS) via the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS). Check out the announcement from the NSIDC Distributed Active Archive Center (DAAC). bit.ly/4dKT46r

NSIDC's Snow Today now covers Alaska and four western Canadian provinces. The US West's snow drought drags on with snow-covered area for March ranking last in the 26-year satellite record. Though heavy snow fell in Colorado and Montana, it quickly melted. bit.ly/4cbo9xI

There are many ways to access and work with NSIDC data to accommodate a wide range of users. Explore web services, interactive tutorials, and other tools using this search interface. nsidc.org/data/user-reso…

What makes snow dens so special? Just because snow is frozen does not mean the temperature of a snowpack is the same from top to bottom. Temperatures vary quite a bit, making a den key for surviving brutal storms. Learn more about on NSIDC's Learn Pages: nsidc.org/learn/parts-cr…

Since its inception, the National Oceanic and Atmospheric Administrations (NOAA's) Arctic Report Card has relied upon NSIDC scientists as authors and/or editors nearly every year, incorporating NSIDC data in every single issue. Read more about its history: bit.ly/4sSBlPg

NASA satellite imagery show the rapid snowmelt off the Sierra Nevadas. Stay current on snow conditions using NSIDC's Snow Today Daily Snow Viewer: nsidc.org/snow-today/sno… Sierra Nevada images: go.nasa.gov/4tf6lIZ

The death spiral continues for iceberg A23a. See the break-up progression from March 27 on the NASA Aqua satellite and April 3 from Terra satellite. The magenta lines outline the iceberg chunks as best as possible through the cloud cover. More MODIS data: nsidc.org/data/modis
