- Ua hāʻawi aku ka US Space Agency NASA i kahi ʻaelike i ke Kulanui o Michigan no ka Cyclone Global Navigation Satellite System (CYGNSS) no ka hana misionari a me ka pani ʻana.
- Me ka pūʻulu o nā microsatellites ʻewalu, hiki i ka ʻōnaehana ke nānā pinepine i nā ʻino a ma ke ʻano hiki ʻole i nā satelite kuʻuna ke hiki, e hoʻonui ana i ka hiki i nā ʻepekema ke hoʻomaopopo a wānana i nā ʻino.
- ʻO ka huina kālā o ka ʻaelike ma kahi o $39 miliona. Aia ka CYGNSS Science Operations Center ma ke Kulanui o Michigan.
No nā makahiki he nui, ua hana nui ʻo NASA i ka hoʻohana ʻana i nā satelite nānā i ka Honua e hōʻiliʻili i ka ʻikepili i koi ʻia e hānai i nā hiʻohiʻona wānana huahelu. Ke hoʻomau nei ʻo CYGNSS i kēlā hana, me ka hoʻohana ʻana i kahi ʻenehana ʻike mamao i kapa ʻia ʻo "GPS signal scattering" e ʻike ma waena o ka ua nui e hoʻohālikelike i ka ikaika o ka makani ʻili i loko o nā ʻōpū o loko o nā ʻino.
"ʻO CYGNSS he misionari paionia i hāʻawi mai iā mākou i ka ʻike hou i ka dynamics o ka hoʻoikaika wikiwiki ʻana i nā ʻino ʻino," wahi a Karen St. Germain, ka luna o ka NASA's Earth Science Division. “He mea hana ikaika nō hoʻi ʻo CYGNSS no ka ʻike ʻana i ka waikahe ma luna o ka ʻāina a me ka moana microplastic debris debris – ʻo ia ke ʻano o ka waiwai hoʻohui a mākou e makemake ai e ʻike, a ʻo ia ke paʻi i ke ala no ka ʻepekema hou aʻe e loaʻa ai nā pōmaikaʻi koʻikoʻi o ke kaiāulu."
Pono nā ana mai CYGNSS no ka noiʻi ʻana i ka hoʻomohala ʻana i ka algorithm, ka nānā ʻana e kōkua i nā hana hoʻohālike e hiki mai ana, a me nā haʻawina kaʻina hana honua.
ʻO nā hana hou aʻe e hiki ai ke noiʻi hou i ka nānā ʻana i ka loli ʻana o ke aniau no ka wā lōʻihi a hoʻonui i ka nui o nā hanana koʻikoʻi e hiki ke kōkua i ka hoʻohālike a me ka wānana. Ke hoʻomau nei nā satelite CYGNSS i nā ana 24/7 o ka makani ʻili o ka moana, ma ka honua a me nā ʻino ʻino, hiki ke hoʻohana ʻia no ke aʻo ʻana i nā kaʻina meteorological a hoʻomaikaʻi i nā wānana o ka wā. Ma ka ʻāina, lawe nā satelite i nā ana mau o ka wai kahe a me ka lepo lepo i hoʻohana ʻia i nā haʻawina kaʻina hydrological a no ka nānā ʻana i nā pōʻino.
He aha e lawe ʻia mai kēia ʻatikala:
- “CYGNSS is also a powerful tool for flood detection on land and ocean microplastic debris detection – that’s the kind of added value we love to see, and it’s paving the way for more science that will have significant societal benefits.
- With a constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’.
- CYGNSS satellites continue to take 24/7 measurements of ocean surface winds, both globally and in tropical cyclones, which can be used to study meteorological processes and improve numerical weather forecasts.
