Advanced Technology Microwave Sounder

Advanced Technology Microwave Sounder (ATMS)  bụ radiometer microwave nke nwéré ọwa iri abụọ na abụọ màkà nyocha nkè ikuku na elu ụwa. Ọ bụ ónyé nọchiri Advanced Microwave Sounding Unit (AMSU) na satellite ihu igwe NOAA.  na-efe ụgbọelu ATMS na Suomi NPP na Joint Polar Satellite System .
