NASA Moderate Resolution Imaging Spectroradiometer (MODIS) sensors have functioned well for decades. What comes next? Visible Infrared Imaging Radiometer Suite (VIIRS)! Data sets are available from the NASA NSIDC DAAC.

See how researchers cooked up collaborative resources on how to use the the NASA Earthdata Cloud.

Growing crops means understanding soil moisture, and the NASA NSIDC Distributed Active Archive Center (DAAC) has data for that.

The continuous satellite record for Arctic sea ice monitoring started in late October 1978, but rescued Nimbus data sets, available from the NASA NSIDC DAAC, go back to the 1960s.

Can you drink melted sea ice? Find the answer to this question and other questions about sea ice in NSIDC's Learn section of our website.

The ICESat-2 Calibration/Validation Land, Vegetation, and Ice Sensor (LVIS) L3A Sea Ice Freeboard from the NASA NSIDC DAAC has high-resolution sea ice freeboard estimates from airborne measurements collected over the Arctic Ocean.

NOAA@NSIDC has released Version 2 of the Canadian Ice Service Arctic Regional Sea Ice Charts in SIGRID-3 Format for ice concentration, development stage, & ice form. This version extends the data record from 2006 to 1968 through the present.

The NASA NSIDC DAAC has released the SnowEx23 Oct23 IOP Snow Pits and Substrate Conditions at Freeze Up data set. It has snow pit measurements collected during the NASA SnowEx October 2023 Intensive Observation Period in Alaska.

The NASA NSIDC DAAC ICESat/GLAS collection has data products derived from the Geoscience Laser Altimeter System (GLAS) instrument, from 2003 to early 2010. Parameters include sea ice, glacier, and ice sheet elevation, ice roughness, and more.

The Extreme Ice Survey Glacier Image Archive at NSIDC holds 1.5 million images from time-lapse cameras (2007-2022), capturing rapid changes in arctic and alpine landscapes. This collection provides crucial data on the speed and extent of glacial retreat.

Display browse images from five different NOAA@NSIDC Arctic sea ice products in a spreadsheet-like format. The tool allows you to quickly compare different time periods and regions in a tabular view. Check it out:

The Global Land Ice Measurements from Space (GLIMS) Glacier Viewer from the NASA NSIDC DAAC lets you compare glacier outlines from versions 6 and 7 of the Randolph Glacier Inventory.

Summer was cool and stormy over the Arctic Ocean. The Arctic sea ice extent average for September was thirteenth lowest in the satellite record. Antarctic sea ice extent dropped sharply through September, hitting record-low daily extents since October 2.

A new study from NSIDC research affiliate Alia Khan shows that penguin poop, a light-absorbing shade of green, melts snow. The penguin poop fertilizes snow algae blooms, and as temperatures rise, snow-algae habitats spread, darkening the snow surface.

Getting started with earthaccess? The NASA NSIDC Distributed Active Archive Center has got you covered.

The NASA NSIDC DAAC has released the ICESat-2 Cal/Val 2022 L2 CHIR Green Wavelength Lidar Arctic Sea Ice Heights and Bathymetry data set. It has Arctic summer sea ice heights and bathymetry, and aims to evaluate positional accuracies of ATLAS measurements.
