Tshuab hnub qub xa xov xwm (satellite) GOES-16 thiab GOES-18
Lub tshuab hnub qub xa xov xwm (satellite) GOES-16 thiab 18 kiv ncig lub ntiaj teb thiab txheeb xyuas rau tib qho chaw ntawm lub ntiaj teb. Nws muab cov duab tshiab txhua 5 feeb, nyob rau feem ntau. Ob lub tshuab hnub qub xa xov xwm (satellite) no yam nriav pom hluav taws kub thiab taug qab qhov hluav taws kub ntawd tau raws nws lub neej.
Lub tshuab hnub qub xa xov xwm (satellite) MODIS thiab VIIIRS
Ob lub tshuab hnub qub xa xov xwm (satellite) no yuav yees cov duab pom tseeb tawm lub ntiaj teb. Feem ntau nws yuav yees duab li ob peb zaug nyob rau hauv ib hnub. Vim tias cov no paub tau meej dua lub tshuab hnub qub xa xov xwm (satellite) GOES, nws tuaj yeem nnriav pom cov hluav taws me dua.
Cov tshuab tiv thaiv hluav taws kub perimeter
Cov tshuab tiv thaiv perimeter rau cov hluav taws kub loj, nyob rau tam sim no tso rau pom ze rau lub sij hawm tseeb tiag thiab hloov kho txhua hnub. Mus saib tau rau ntawm GeoMAC txhawm rau kev paub ntau ntxiv.
Cov koob yees duab
Cov koob yees duab soj qab xyuas cov cheeb tsam muaj kev phom sij ntawm hluav taws kub hnyiab tas li. Xaiv lub cim koob yees duab txhawm rau kom qhib lub koob yees duab saib. Cov xib xub taw kev qhia txog cov kev taw seem ntawm lub koob yees duab uas tab tom tig rau.
Chaw ntsuas huab cua
Cov chaw ntsuas huab cua yuav sib txawv nyob ntawm hom ntaub ntawv qhia paub uas khaws tseg. Tej hom tuaj yeem tshaj tawm cov cua nkaus xwb, ho tej hom hos tuaj yeem tshaj tawm qhov kub txias tau. Xaiv rau lub cim ntawm lub chaw tsuas txhawm rau saib cov ntaub ntawv.
Cov xwm txheej CAL FIRE
California Department of Forestry and Fire Protection (CAL FIRE) li kev tawm tsawm rau cov xwm txheej ceev fab hluav taws kub hauv Xeev California. CAL FIRE yuav tshaj tawm cov ntsiab lus meej ntxaws rau qhov xwm txheej loj ntawm lawv lub vev xaib. Peb daim ntawv qhia suav nrog cov cim rau kev tshaj tawm cov hluav taws kub loj uas tsawg dua 100% kev ntim tau. Mus saib tau rau ntawm cov ntaub ntawv qhia paub txog lub chaw hauj lwm CAL FIRE.
Kev Ceeb Toom Ua Tus Chij Liab
Kev Ceeb Toom Ua Tus Chij Liab raug plov meej los ntawm National Weather Service. Qhov no tshwm sim thaum qhov kub txias ntawd kub tuaj, tsis muaj qhov noo thiab cua daj cua dub loj heev uas tuaj yeem ua rau muaj kev phom sij ntawm hluav taws kub. Siv cov kev lim no los saib cov cheeb tsam tam sim no uas nyob rau hauv qhov Kev Ceeb Toom Chij Liab. Mus saib tau rau ntawm National Weather Service kom paub txog cov kev ceeb toom ntawm lub chaw hauj lwm.
Txhua cov kev tiv thaiv tshawb pom hluav taws kub
Qhov no teev tag nrho cov hluav taws kub nyob rau tam sim no uas kuaj pom hauv Xeev California. Nws muaj xws li:
- Tshaj tawm ntawm lub tshuab hnub qub xa xov xwm (satellite)
- Lub Nroog
- Lub sij hawm ntawm kev tshawb pom thawj zaug thiab zaum kawg
- Cov xuab ntawm lub sij hawm
- Kev tshawb pom qhov kub heev
- Thaj chaw sib koom tes thiab tus lej ID rau txhua qhov kev kuaj pom
Xaiv lub cim hluav taws txhawm rau los saib cov ntsiab lus ntawm qhov xwm txheej. Hom kev qhia meej ntxaws ntawd yuav txawv, nyob ntawm seb lub tshuab hnub qub xa xov xwm (satellite) twg tau tshaj tawm. Qee kev qhia meej ntxaws tuaj yeem muaj xws li:
- Koog Chaw Uas Muaj Teeb Meem Hluav Taws Kub Tas Li (High Fire-Threat District)
California Public Utilities Commission (CPUC) tau txheeb xyuas thaj chaw muaj hluav taws kub hav zoov, raws li tau pom nyob rau hauv Daim Duab Qhia Chaw Koog Chaw Uas Muaj Teeb Meem Hluav Taws Kub Tas Li (High Fire-Threat District). Qee cov tshuab hnub qub xa xov xwm (satellite) tshaj tawm txog seb puas muaj hluav taws kub nyob hauv ib qho ntawm cov cheeb tsam uas muaj kev pheej hmoo siab. - Fire Radiative Power (FRP)
FRP yog cov sab ci uas qhov kub ntawm hluav taws xob tso tawm. Nws muaj feem cuam tshuam nrog kev siv hluav taws kub hauv ib cheeb tsam. FRP tuaj yeem muaj ntawm ncua 0 megawatts (qhov ci qis heev) mus rau ntau dua 10,000 megawatts (qhov ci sib heev). Qhov ci uas qis ntawm kev hluav iav feem ntau lawm yuav muaj FRP tsawg dua 1,000 megawatts. - Cov pixel uas puv npo
Thaum FRP mus nce txog nws qhov ncua ciaj ciam txwv lawm, ces cov ntaub ntawv dhau los ua "puv npo." Qhov no feem ntau tsuas yog tshwm sim nyob rau cov hluav taws kub loj heev xwb. - Cov pixel muaj huab niab xyaw
Qhov no qhia tau hais tias cov huab npog los sis cov pa yog ib feem ntawm los npog rau chaw ntawm lub ntiaj teb. Cov huab ntom tuaj ntawd tuaj yeem cuam tshuam rau kev muab cov ntaub ntawv qhia paub uas raug.
