Since beginning to migrate data to the NASA Earthdata Cloud, the NSIDC DAAC has worked to develop resources and tools to ensure an easy transition for data users. The newest of those tools to come to the NSIDC DAAC is NASA Earthdata Harmony data transformation services, or Harmony for short, which the NSIDC DAAC has adopted for ICESat-2 data. Harmony is a framework that serves many NASA Earthdata data sets across NASA DAACs. These data transformation services include spatial, temporal, and variable subsetting, reformatting the data, combining multiple files together in one file, reprojection, and more.

Following the pattern seen in recent years, autumn freeze up has been slow in the Arctic, reflecting the growing heat gain in the ocean mixed layer during summer and higher air temperatures. In the Antarctic, the rate of spring ice loss slowed somewhat during November, ending the month above the extreme low levels of 2016 and 2023.

Starting in 2015, data from the NASA Soil Moisture Active Passive (SMAP) satellite were collected using GPS signals. They had been stored, but not processed, because to do so required expertise in

The 2024 melt season for the Greenland Ice Sheet ended with the second-lowest cumulative daily melt extent in this century, ranking twenty-eighth in the satellite record, which began in 1979. A late summer heat wave along the northwestern ice sheet closed out the season.

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.
