摘要：

High-resolution observations of the Q branch of the 2ν2 band of phosphine at 1972 cm-1 on Jupiter show an enhancement of the PH3 concentration in the deep troposphere (p≥1 bar) by about 60% at high Northern (∼50°N) latitudes compared to both the North Equatorial Belt and the Great Red Spot. Difference in photochemistry or in deep vertical diffusion of PH3 could be involved to interpret such variations. © 1990.
