A series of atmospheric rivers significantly increased snow-covered area and snow water equivalent in the California Sierra Nevada, and to a lesser extent the delivery of snow inland to Nevada, Utah, and Colorado. Snow-covered area for the western United States was 125 percent of average for January with above average snow cover in most regions. 

Surface melting over Antarctica was near-average through January, but above average surface melting occurred on both the northeastern and southwestern areas of the Antarctic Peninsula.

The Global Lake and River Ice Phenology Database (G01377), archived by NOAA@NSIDC, has some of the oldest observations on record at NSIDC. The database includes observations dating back to the ninth century.

On November 30, 2022, the White House released a guidance document that identifies ELOKA as an example of a successful data management program that serves both Indigenous communities and federal agencies. 

As the peak of Antarctica's melt season approaches, surface snow melting has been widespread over coastal West Antarctica, with much of the low-lying areas of the Peninsula and northern West Antarctic coastline showing 5 to 10 days more melting than average. However, much of the East Antarctic coast is near average.
