Description
Total column water vapour (TCWV) can be retrieved in the visible “blue” spectral range (430-450nm) using Differential Optical Absorption Spectroscopy (DOAS). This spectral range offers several advantages, for instance it allows for accurate, straightforward retrievals over ocean and land even under partly-cloudy conditions.
To investigate climate changes in the global TCWV distribution, we make use of the long-term observations of the Ozone Monitoring Instrument (OMI) on board NASA’s Aura satellite and present a global analysis of TCWV trends retrieved from multiple years of OMI measurements (2005-2020). Additionally, we put our results in context to trends of other climate data records.
