Le mephu, eyenziwe kusetshenziswa ukubonwa okusha kwe-COWVR, ikhombisa amaza omhlaba e-microwave, ahlinzeka ngolwazi mayelana namandla omoya wolwandle, inani lamanzi emafwini, kanye nenani lomhwamuko wamanzi emkhathini.
Ithuluzi elincane elisha elise-International Space Station lidale imephu yokuqala yomhlaba wonke yomswakama nomoya wolwandle.
Ngemva kokufakwa eSiteshini Somkhathi Samazwe Ngamazwe, amathuluzi amabili amancane aklanywe futhi akhiwa yi-Jet Propulsion Laboratory ye-NASA eSouthern California aqalwa ngoJanuwari 7 ukuze kuqalwe ukuqoqa idatha ngemimoya yolwandle kanye nomhwamuko wamanzi womkhathi osetshenziselwa ukubikezela isimo sezulu nolwandle. Kudingeka ulwazi olubalulekile. Zingakapheli izinsuku ezimbili, i-Compact Ocean Wind Vector Radiometer (COWVR) kanye ne-Temporal Space Experiment in Storms and Tropical Systems (TEMPEST) zase ziqoqe idatha eyanele ukuqala ukudala imephu.
I-COWVR kanye ne-TEMPEST zethulwe ngoDisemba 21, 2021, njengengxenye yomsebenzi we-SpaceX wokuphinda kuthengiswe kabusha kwezentengiselwano wama-24 ku-NASA. Zombili lezi zinsimbi ziyi-microwave radiometers ezilinganisa izinguquko emisebeni yemvelo ye-microwave yoMhlaba. Lezi zinsimbi ziyingxenye yoHlelo Lokuhlola Isikhala lwe-US Space Force's Houston-8 (STP-H8), oluhlose ukukhombisa ukuthi zingaqoqa idatha yekhwalithi efanayo nezinsimbi ezinkulu ezisebenza njengamanje ku-orbit.
Le mephu entsha evela ku-COWVR ikhombisa ama-microwave angu-34 GHz akhishwa yiMhlaba kuzo zonke izifunda ezibonakala esiteshini sasemkhathini (kusukela kuma-degree angu-52 enyakatho ye-latitude kuya kuma-degree angu-52 eningizimu ye-latitude). Lo msinga okhethekile we-microwave unikeza ababikezeli bezulu ulwazi mayelana namandla omoya ebusweni bolwandle, inani lamanzi emafwini, kanye nenani lomhwamuko wamanzi emkhathini.
Imibala eluhlaza nomhlophe emephini ikhombisa amazinga aphezulu omhwamuko wamanzi namafu, kuyilapho umbala oluhlaza okwesibhakabhaka omnyama wolwandle ubonisa umoya owomile nesibhakabhaka esicacile. Isithombe sithwebula izimo zezulu ezijwayelekile njengomswakama wezindawo ezishisayo kanye nemvula (umugqa oluhlaza maphakathi nemephu) kanye neziphepho eziphakathi nendawo phezu kolwandle.
Ama-radiometer adinga i-antenna ejikelezayo ukuze akwazi ukubona izindawo ezinkulu zobuso boMhlaba kunokuba abone umugqa omncane nje. Kuzo zonke ezinye i-radiometer ze-microwave zasemkhathini, hhayi i-antenna kuphela, kodwa ne-radiometer uqobo kanye ne-electronics ezihambisanayo zijikeleza cishe izikhathi ezingu-30 ngomzuzu. Kunezizathu ezinhle zesayensi nezobunjiniyela zomklamo onezingxenye eziningi ezijikelezayo, kodwa ukugcina i-spacecraft izinzile ngesisindo esiningi esinyakazayo kuyinselele. Ngaphezu kwalokho, izindlela zokudlulisa amandla nedatha phakathi kwezinhlangothi ezijikelezayo nezimile zethuluzi ziye zabonakala zidinga umsebenzi omningi futhi kunzima ukuzikhiqiza.
Ithuluzi elihambisanayo le-COWVR, i-TEMPEST, liwumphumela wamashumi eminyaka okutshalwa kwezimali kwe-NASA kwezobuchwepheshe ukwenza i-electronics yasemkhathini ibe ncane kakhulu. Maphakathi nawo-2010, unjiniyela we-JPL uSharmila Padmanabhan waqala ukucabanga ngokuthi yimiphi imigomo yesayensi engafinyelelwa ngokubeka izinzwa ezincane ku-CubeSats, amasathelayithi amancane kakhulu avame ukusetshenziselwa ukuhlola imiqondo emisha yokuklama ngentengo ephansi.
Uma ufuna ukwazi ngeziteshi zezulu ezincane, ungaxhumana nathi.
