The spatial distribution of water, ammonia, phosphine, germane, and arsine in the Jupiter's troposphere has been inferred from the Jovian Infrared Auroral Mapper (JIRAM) Juno data. Measurements allow us to retrieve the vertically averaged concentration of gases between ~3 and 5 bars from infrared‐bright spectra. Results were used to create latitudinal profiles. The water vapor relative humidity varies with latitude from <1% to over 15%. At intermediate latitudes (30–70°) the water vapor maxima are associated with the location of cyclonic belts, as inferred from mean zonal wind profiles (Porco et al., 2003). The high‐latitude regions (beyond 60°) are drier in the north (mean relative humidity around 2–3%) than the south, where humidity reaches 15% around the pole. The ammonia volume mixing ratio varies from 1 × 10⁻⁴ to 4 × 10⁻⁴. A marked minimum exists around 10°N, while data suggest an increase over the equator. The high‐latitude regions are different in the two hemispheres, with a gradual increase in the south and more constant values with latitude in the north. The phosphine volume mixing ratio varies from 4 × 10⁻⁷ to 10 × 10⁻⁷. A marked minimum exists in the North Equatorial Belt. For latitudes poleward 30°S and 30°N, the northern hemisphere appears richer in phosphine, with a decrease toward the pole, while the opposite is observed in the south. JIRAM data indicate an increase of germane volume mixing ratio from 2 × 10⁻¹⁰ to 8 × 10⁻¹⁰ from both poles to 15°S, with a depletion centered around the equator. Arsine presents the opposite trend, with maximum values of 6 × 10⁻¹⁰ at the two poles and minima below 1 × 10⁻¹⁰ around 20°S.

从朱诺·吉拉姆数据推论木星对流层次要物种的空间分布

木星对流层中水，氨，磷化氢，锗烷和砷化氢的空间分布已根据Jovian红外极光测绘仪（JIRAM）Juno数据得出。通过测量，我们可以从红外明亮光谱中检索到3到5巴之间的垂直平均气体浓度。结果用于创建纬度轮廓。水蒸气相对湿度随纬度从<1％到超过15％变化。从平均纬向风廓线推断，在中纬度（30-70°），水汽最大值与气旋带的位置有关（Porco等，2003）。高纬度地区（超过60°）在北部（平均相对湿度约为2％至3％）比南部干燥，在南部，极点周围的湿度达到15％。氨气体积比为1×10 ^-4至4×10 ^-4。明显的最小值存在于10°N附近，而数据表明赤道有所增加。两个半球的高纬度地区有所不同，南部逐渐增加，北半球纬度更高。膦的体积混合比为4×10 ^-7〜10 ×10 ^-7。北赤道带存在明显的最小值。对于纬向南纬30°S和30°N的纬度，北半球的磷化氢含量较高，向北极的方向降低，而南半球则相反。JIRAM数据表明锗烷体积混合比从2×10 ^-10增加到8×10 ^-10从两极到15°S，损耗以赤道为中心。砷化氢呈现相反的趋势，在两个极点的最大值为6×10 ^-10，在20°S附近最小值低于1×10 ^-10。
