http://dbpedia.org/ontology/abstract The Special Sensor Microwave/Imager (SSM/IThe Special Sensor Microwave/Imager (SSM/I) is a seven-channel, four-frequency, linearly polarized passive microwave radiometer system. It is flown on board the United States Air Force Defense Meteorological Satellite Program (DMSP) Block 5D-2 satellites. The instrument measures surface/atmospheric microwave brightness temperatures (TBs) at 19.35, 22.235, 37.0 and 85.5 GHz. The four frequencies are sampled in both horizontal and vertical polarizations, except the 22 GHz which is sampled in the vertical only. The SSM/I has been a very successful instrument, superseding the across-track and Dicke radiometer designs of previous systems. Its combination of constant-angle rotary-scanning and total power radiometer design has become standard for passive microwave imagers, e.g. TRMM Microwave Imager, AMSR. Its predecessor, the Scanning Multichannel Microwave Radiometer (SMMR), provided similar information. Its successor, the Special Sensor Microwave Imager / Sounder (SSMIS), is an enhanced eleven-channel, eight-frequency system.ed eleven-channel, eight-frequency system. , El Sensor Espacial de Microones/Imatges (eEl Sensor Espacial de Microones/Imatges (en (anglès), special sensor microwave/imager, (SSM/I)) és una família de sensors per a satèl·lits de teledetecció. Els (SSM/I) son radiòmetre de microones de set canals, quatre freqüències, de polarització lineal.Els SSM/I orbiten en els satèl·lits Bloc 5D-2 del Programa de Satèl·lits Meteorològics de Defensa (DMSP) de la USAF. L'instrument mesura la de la superfície terrestre i de l'atmosfera a les freqüències 19.35, 22.235, 37.0 i 85.5 GHz. Les quatre freqüències són mesurades en polarització horitzontal i vertical, excepte per 22 GHz que es mesura tan sols en polarització vertical El SSM/I ha estat un instrument molt reeixit, que substitueix a la través de la trajectòria i l'arquitectura de dels sistemes anteriors per una arquitectura de radiòmetre de potència total. La plataforma satel·litària, que té un angle de gir constant d'escaneig s'ha convertit en estàndard per als generadors d'imatges de microones passius, per exemple, TRMM Microwave Imager, AMSR. El seu predecessor, el scanning multichannel microwave radiometer (SMMR) proporciona informació similar. El seu successor, el Special Sensor Microwave Imager/Sounder (SSMIS), és una millora d'aquest i té d'onze canals, vuit freqüències.uest i té d'onze canals, vuit freqüències.
