Figure number: Figure 3.12 From the IPCC Working Group I Contribution to the Sixth Assessment Report: Chapter 3
Column water vapor path trends (%/decade) for the period 1988-2019 averaged over the near-global oceans (50°S-50°N). The figure shows satellite data (RSS) and ERA5.1 reanalysis, as well as CMIP5 (sky blue) and CMIP6 (brown) historical simulations. All available ensemble members were used (see Section 3.2. Fits to the model trend probability distributions were performed with kernel density estimation. Figure is updated from Santer et al. (2007).

cmorized with esmvaltool/cmorizers/obs/cmorize_obs_rss.ncl (in the ar6_chapter_3 branch, not in the main ESMValTool branch, yet) using the "precipitable_water" variable. The "fixed coverage" mask was produced from the same file, using "precipitable_water_climatology" and "precipitable_water_anomaly" with a tool based on the cmorizer: esmvaltool/cmorizers/obs/cmorize_obs_rssanom.ncl.
