Le mephu, idalwe kusetyenziswa uqwalaselo olutsha lwe-COWVR, ibonisa i-earth microwave frequencies, enika ulwazi malunga namandla omoya ophezu kolwandle, ubungakanani bamanzi emafini, kunye nobuninzi bomphunga wamanzi kwi-atmosfera.
Isixhobo esincinci esitsha esikwiSikhululo saseMajukujukwini saMazwe ngaMazwe senze imephu yokuqala yehlabathi yokufuma kunye nempepho yolwandle.
Emva kofakelo kwiSikhululo saMajukujuku saMazwe ngaMazwe, izixhobo ezibini ezincinci eziyilwe zaza zakhiwa yiNASA's Jet Propulsion Laboratory eSouthern California zaye zasungulwa ngoJan. 7 ukuqalisa ukuqokelela idatha ngemimoya yolwandle yoMhlaba kunye nomphunga wamanzi asemoyeni ezisetyenziselwa uqikelelo lwemozulu nolwandle.Ulwazi oluphambili luyafuneka.Kwisithuba seentsuku ezimbini, iCompact Ocean Wind Vector Radiometer (COWVR) kunye neTemporal Space Experiment kwiStorm and Tropical Systems (TEMPEST) yayiqokelele idatha eyaneleyo ukuqalisa ukuyila imaphu.
I-COWVR kunye ne-TEMPEST yaphehlelelwa nge-21 kaDisemba, ngo-2021, njengenxalenye ye-SpaceX's 24th mission resupply yentengiso kwiNASA.Zombini ezi zixhobo ziiradiometers zemicrowave ezilinganisa utshintsho kwimitha yendalo ye-microwave.Izixhobo ziyinxalenye yeNkqubo yoVavanyo lweSithuba se-US Space Force i-Houston-8 (STP-H8), ejolise ekuboniseni ukuba inokuqokelela idatha yomgangatho othelekisekayo kwizixhobo ezinkulu ezisebenza ngoku kwi-orbit.
Le mephu intsha isuka kwi-COWVR ibonisa ii-microwaves ezingama-34 GHz ezikhutshwa nguMhlaba kuzo zonke izibanzi ezibonakalayo ukusuka kwisikhululo sasemajukujukwini (ukusuka kwi-52 degrees latitude emantla ukuya kwi-52 degrees latitude emazantsi).Esi sihlandlo sikhethekileyo se-microwave sinika ababikezeli bemozulu ngolwazi malunga namandla omoya kumphezulu wolwandle, ubungakanani bamanzi asemafini, kunye nobungakanani bomphunga wamanzi kwiatmosfera.
Imibala eluhlaza nemhlophe kwimephu ibonisa amanqanaba aphezulu omphunga wamanzi kunye namafu, ngelixa umbala oluhlaza okwesibhakabhaka obumnyama wolwandle ubonisa umoya owomileyo kunye nesibhakabhaka esicacileyo.Umfanekiso ubamba iimeko zemozulu eziqhelekileyo ezifana nokufuma kwetropikhi kunye nemvula (umgca oluhlaza embindini wemephu) kunye nezaqhwithi zobude obuphakathi phezu kolwandle.
Iiradiometers zifuna i-eriyali ejikelezayo ukuze zikwazi ukujonga iindawo ezinkulu kumphezulu woMhlaba kunomgca omxinwa nje.Kuzo zonke ezinye ii-radiometers ze-microwave, hayi i-eriyali kuphela, kodwa neradiometer ngokwayo kunye ne-electronics ehambelana nayo zijikeleza malunga namaxesha angama-30 ngomzuzu.Kukho izizathu ezilungileyo zenzululwazi kunye nezobunjineli zoyilo olunamalungu amaninzi ajikelezayo, kodwa ukugcina isiphekepheke sizinzileyo esinobunzima obuninzi obushukumayo kulucelomngeni.Ukongeza, iindlela zokudlulisa amandla kunye neenkcukacha phakathi kwamacala ajikelezayo kunye namileyo esixhobo zibonakalise ukuba zinzima kakhulu kwaye kunzima ukwenza.
Isixhobo esincedisayo se-COWVR, i-TEMPEST, sisiphumo samashumi eminyaka yotyalo-mali lwe-NASA kubuchwephesha bokwenza i-electronics yendawo ihlangane ngakumbi.Embindini we-2010s, injineli ye-JPL u-Sharmila Padmanabhan waqala ukucinga malunga nokuba zeziphi iinjongo zenzululwazi ezinokufezekiswa ngokubeka i-compact sensors kwi-CubeSats, iisathelayithi ezincinci kakhulu ezihlala zisetyenziselwa ukuvavanya iingcamango ezintsha zoyilo.
Ukuba ufuna ukwazi malunga nezikhululo zemozulu ezincinci, ungaqhagamshelana nathi.
