As well as contaminating soil moisture data over land, radio-frequency interference also affects ocean salinity data. An arc of contamination, which is due to interference from radar systems in North America, can clearly be seen stretching across the Arctic Ocean. The interference displays a much higher brightness temperatures than the relatively stable brightness temperatures over oceans. The situation is likely to improve in the near future as there are plans to refurbish networks in North America.
