Le mephu, eyenziwe kusetyenziswa ukujongwa kweCOWVR entsha, ibonisa amaza e-microwave oMhlaba, anika ulwazi malunga namandla omoya wolwandle, ubungakanani bamanzi emafini, kunye nobungakanani bomphunga wamanzi emoyeni.
Isixhobo esincinci esitsha esikwiSikhululo seeNdawo saMazwe ngaMazwe senze imephu yokuqala yehlabathi yomswakama kunye nemimoya yolwandle.
Emva kokufakwa kwiSikhululo seSithuba saMazwe ngaMazwe, izixhobo ezimbini ezincinci eziyilwe nezakhiwe yiJet Propulsion Laboratory yeNASA eMzantsi California zaqaliswa ngoJanuwari 7 ukuqala ukuqokelela idatha ngemimoya yolwandle yoMhlaba kunye nomphunga wamanzi omoya osetyenziselwa uqikelelo lwemozulu nolwandle. Ulwazi olubalulekileyo luyafuneka. Kwiintsuku ezimbini, iCompact Ocean Wind Vector Radiometer (COWVR) kunye neTemporal Space Experiment in Storms and Tropical Systems (TEMPEST) zaziqokelele idatha eyaneleyo ukuqala ukwenza imephu.
I-COWVR kunye ne-TEMPEST zaqaliswa ngoDisemba 21, 2021, njengenxalenye yomsebenzi we-SpaceX wokubuyisela kwakhona umbane kwi-NASA. Zombini ezi zixhobo zii-microwave radiometers ezilinganisa utshintsho kwimitha yendalo ye-microwave yoMhlaba. Ezi zixhobo ziyinxalenye yeNkqubo yoVavanyo lweSithuba ye-US Space Force's Houston-8 (STP-H8), ejolise ekuboniseni ukuba zinokuqokelela idatha yomgangatho ofanayo nezixhobo ezinkulu ezisebenza kwi-orbit ngoku.
Le mephu intsha evela kwi-COWVR ibonisa ii-microwave ezingama-34 GHz ezikhutshwa nguMhlaba kuzo zonke iilatitude ezibonakalayo ukusuka kwisikhululo sasemajukujukwini (ukusuka kwiidigri ezingama-52 ukuya kwiidigri ezingama-52 ukuya kuma-digri angama-52 ukuya kumajukujukwini asezantsi). Olu phindaphindo lukhethekileyo lwe-microwave lubonelela ababikezeli bemozulu ngolwazi malunga namandla omoya kumphezulu wolwandle, ubungakanani bamanzi emafini, kunye nobungakanani bomphunga wamanzi emoyeni.
Imibala eluhlaza nemhlophe emephini ibonisa amanqanaba aphezulu omphunga wamanzi namafu, ngelixa umbala oluhlaza okwesibhakabhaka omnyama wolwandle ubonisa umoya owomileyo kunye nesibhakabhaka esicacileyo. Umfanekiso uthatha iimeko zemozulu eziqhelekileyo ezifana nokufuma kwetropiki kunye nemvula (umgca oluhlaza embindini wemephu) kunye nezivuthuvuthu eziphakathi kwelatitude phezu kolwandle.
Ii-Radiometer zifuna i-antenna ejikelezayo ukuze zikwazi ukubona iindawo ezinkulu zomphezulu woMhlaba kunokuba zibone umgca omxinwa. Kuzo zonke ezinye ii-radiometer ze-microwave zesithuba, kungekuphela nje i-antenna, kodwa ne-radiometer ngokwayo kunye nee-elektroniki ezinxulumene nayo zijikeleza malunga namaxesha angama-30 ngomzuzu. Kukho izizathu ezilungileyo zesayensi nezobunjineli zoyilo oluneendawo ezininzi ezijikelezayo, kodwa ukugcina i-spacecraft izinzile enobunzima obuhambayo obuninzi ngumceli mngeni. Ukongeza, iindlela zokudlulisa amandla kunye nedatha phakathi kwamacala ajikelezayo namileyo esixhobo ziye zabonakala ngathi zinzima kwaye kunzima ukuzenza.
Isixhobo esincedisayo seCOWVR, iTEMPEST, sisiphumo samashumi eminyaka otyalo-mali lweNASA kubuchwepheshe ukwenza izixhobo ze-elektroniki zasesibhakabhakeni zibe ncinci ngakumbi. Phakathi kwiminyaka yoo-2010, injineli yeJPL uSharmila Padmanabhan waqala ukucinga ngeenjongo zesayensi ezinokufezekiswa ngokubeka ii-compact sensors kwiCubeSats, iisathelayithi ezincinci kakhulu ezisetyenziswa rhoqo ukuvavanya iingcamango ezintsha zoyilo ngexabiso eliphantsi.
Ukuba ufuna ukwazi ngezikhululo zemozulu ezincinci, ungaqhagamshelana nathi.
