Absorption of infrared radiation through variation of water vapour transmittance with altitude in the atmosphere for radiation in the 6.3mm absorption band was studied using Goody model on pressure and temperature at different altitudes (0-16 km) for four months; (March, May, August and September, 2019) in Abeokuta metropolis. Computed results indicated, showed that water vapour transmittance decreased with increase in altitude (Z) at 2 km < Z ≤ 16 km (throughout the study period) due to absorption of infrared radiation by water vapour in the troposphere. The observed trend was attributed to the effect of warming on the lower troposphere
