地球 (Tē-kiû)的 (ê)大氣圈 (tāi-khì-khoan)是 (sī)一重 (chi̍t-têng)包 (pau)墊 (tiām)地球四圍 (sì-ûi)，受 (siū)重力 (tāng-le̍k)搝 (giú)牢 (tiâu)的氣體 (khì-thé)，就 (tō)是一般 (it-poaⁿ)講 (kóng)的空氣 (khong-khì)。地球的大氣圈所 (só͘)創造 (chhòng-chō)的壓力 (ap-le̍k)，予 (hō͘)液態 (e̍k-thài)的子 (chú)通 (thang)存在 (chûn-chāi)佇 (tī)地球表面 (piáu-bīn)，另外 (lēng-gōa)嘛 (mā)有 (ū)吸收 (khip-siu)紫外線 (chí-gōa-sòaⁿ)，保持 (pó-chhî)溫暖 (un-loán)，佮 (kap)減少 (kiám-chió)極端 (ke̍k-toan)溫度 (un-tō͘)的功能 (kong-lêng)，保護 (pó-hō͘)這 (che)惑星 (he̍k-chheⁿ)頂 (téng)的性命 (sèⁿ-miā)。

組成 (Cho͘-sêng)[修改]

今 (Taⁿ)空氣的主要 (chú-iàu)組成，照 (chiàu)體積 (thé-chek)[1]
氣體 體積(A)
號名 (Hō-miâ) 化學式 (Hòa-ha̍k-sek) ppmv(B) %
Chit素 (sò͘) N2 780,840 78.084
酸素 (Sng-sò͘) O2 209,460 20.946
Argon Ar 9,340 0.9340
二酸化 (Jī-sng-hòa)炭素 (thòaⁿ-sò͘) CO2 400 0.04[2]
Neon Ne 18.18 0.001818
Helium He 5.24 0.000524
Methane CH4 1.79 0.000179
無 (Bô)含 (hâm)佇頂面 (téng-bīn)的今空氣:
水蒸氣 (Chúi-cheng-khì)(C) H2O 10–50,000(D) 0.001%–5%(D)
註解 (chù-kái):

(A) 佇理想 (lí-sióng)氣體，體積分率 (hun-lu̍t)是等於 (téng-û)mole分率,
    另外看 (khòaⁿ)體積 (熱力學 (jia̍t-le̍k-ha̍k))
(B) ppmv: 用 (ēng)體積算 (sǹg)的百萬分一 (pah-bān-hūn-it) (ppm)
(C) 佇規个 (kui-ê)大氣圈子蒸氣 (chú-cheng-khì)占 (chiàm)0.25% 的 (ê)質量 (chit-liōng)
(D) 水蒸氣照所在 (só͘-chāi)真 (chin)無仝 (kâng)[3]

The NASA total was 17 ppmv over 100%, and CO2was increased here by 15 ppmv. To normalize, N2 should be reduced by about 25 ppmv and O2 by about 7 ppmv.
