WebFeb 1, 2024 · Gaseous absorption due to water vapour and oxygen in the atmosphere causes the resonance up to ∼300 GHz. For oxygen and water vapour the strong band of resonances is around 57–60 and 22 GHz, respectively. The attenuation varies with the amount of water vapour present in the atmosphere. WebOxygen dissolved in the Water at atmospheric pressure can be calculated as: co = (1 atm) 0.21 / (756.7 atm/ (mol/litre)) (31.9988 g/mol) = 0.0089 g/litre ~ 0.0089 g/kg Nitrogen dissolved in the Water at atmospheric …
