Short summary

There is growing interest in hydrogens impact on atmospheric chemistry and climate. Here, the seasonality of hydrogen oxidation and loss to microbial activity in soils are investigated using information from the hydrofluorocarbon, HFC-152a. A large seasonal range of the soil sink, over twice that of hydroxyl loss, is seen in the Northern latitudes peaking in the late summer, while the Southern latitudes show a much lower range. This will be useful for validating model hydrogen cycles.
