description |
International audience Water vapor is defined as a major climate indicator at many occasions, highly variable spatially and temporarily, water vapor has the most important natural GHG effect, through his high infra-red absorption capacity, and temperature changes sensitivity, water vapor affects the Earth radiative budget and energy transfer, evolved at many atmospheric dynamics including the cloud formation and the aerosols composition. As a consequence to the accelerated transition towards the new climate especially above the arctic, and to investigate the feedback to the arctic amplification and the global warming, we study the water vapor variability and trends on a relatively long term above the arctic region, using the Total Column Water Vapor retrieval from MODIS/NIR spectro-radiometer on board of TERRA satellite. These 15 Years monthly daytime satellite data were compared to GPS integrated water vapor over four selected NDACC polar stations: Sodankyla-Finland, Ny-Alesund –Svalbard, Thule-Greenland, Scoresbysund-Greenland. GPS data are calculated with the temperature and pressure profile of the nearest coastal ERA-Interim station. These data were filtered for nearly coincident time to satellite over pass in order to exclude the timing effects. Errors, relative biases and RMSE at both monthly and seasonally scales will be presented and discussed. Then the MODIS 15 years linear trends and anomalies above the whole Arctic will be shown with a special focus on sea ice extent decline feed-back and hydrologic cycle connections with respect to heat waves. Results show wetter trends on the Mackenzie and mid-Siberia at September, unlike the European arctic summer which is getting drier, while Svalbard is getting wetter almost all the year. Conclusion and perspectives are also presented. |
