Proposed action is in very narrow connection with this previous action COST 723. Our planned activities are directed to the point D.1 of the Scientific programme of the COST action ES0604 after its Memorandum of Understanding: D.1: Assess and improve the quality of atmospheric water vapour measurements and especially to the items: Laboratory measurements of water vapour absorption, where we plan: Laboratory studies of selected lines of water vapour and measurements of the water vapour continuum absorption are crucial for improving estimates of atmospheric water vapour’s radiative impact. This work will be part of our contribution together with application of laboratories data to the analysis of satellite data. Detailed laboratory studies of selected lines will include: a) Corrections of the absorption coefficients (including the temperature dependence) of selected molecular species where the present quality is critically insufficient b) Measurements of line shape profiles including their mathematical evaluation c) Measurements of pressure broadenings and pressure dependences of line shape profiles including their mathematical evaluation. d) Water vapor continuum absorption measurements The next planned item is close to Evaluation of the accuracy of existing and emerging measurement technique where we intend following activities: Spectroscopic analysis of satellite data a) b) Spectroscopic analysis of Odin data – searching weak and overlapped lines Spectroscopic expertise – support of satellite data analysis Proposed activities are directed to the Workgroup 1: IMPROVING WATER VAPOUR OBSERVATIONS In the focus of our planned aims will be the quality of observational techniques, and how to improve them. This will involve intercomparison exercises and laboratory studies for in-situ techniques, and validation of satellite measurements. In the next, we plan laboratory measurements of water vapour absorption in the form of laboratory studies of selected lines of water vapour and measurements of the water vapour continuum absorption, that are crucial for improving estimates of atmospheric water vapour’s radiative impact.
