Most of Greenland’s meltwater takes weeks to reach the ocean. A recently published study highlights an innovative new method to track Greenland’s meltwater movement: monitoring the bedrock under the ice.

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
