Starting in 2015, data from the NASA Soil Moisture Active Passive (SMAP) satellite were collected and stored using GPS signals, but had not been processed, because to do so required expertise in Global Navigation Satellite System-Reflectometry (GNSS-R), a specific niche in the science community. Nereida Rodriguez-Alvarez, a specialist on GNSS-R techniques, jumped in and helped make sense of the collected data, which is now available at the NASA NSIDC Distributed Active Archive Center (DAAC).
Using NASA Soil Moisture Active Passive (SMAP) data archived at the National Snow and Ice Data Distributed Active Archive Center (NSIDC DAAC), a research team has brought drought forecasting to near real-time.
A newly published study has mapped glacial debris across the Greater Caucasus, the mountainous region between the Black and Caspian Seas. The study found an increasing trend in glacial debris between 2014 and 2020. The authors relied on GLIMS data at NSIDC in their research.
Software engineer and metadata architect Julia Collins discusses how she came to NSIDC, and how she came to appreciate the crucial value of data about data.
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.
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.
