30. Session A: Climate trends from satellite sounding data. • Session B1: Stable time series for key greenhouse gases and other trace species. • Session B2: Remote sensing of atmospheric composition and traceability issues in spectroscopic data. • Session C: Radiation and Earth energy balance. • Session D: Earth surface (land and water) temperature. • Session F: Microwave imagery data in climate and NWP. • Session G: Surface properties: albedo, land cover, and ocean cover. • Session H: Ocean salinity.

31. CIMO mandate • Requirements for high quality observational data and their world-wide compatibility were a governing principle when the International Meteorological Organization (IMO) was established in 1873. • technical standards, • instrument intercomparisons, • testing and calibration • implement quality control procedures. • Responsibilities assigned to the Commission for Instruments and Methods of Observations (CIMO)

32. CIMO Guide The WMO Guide to Meteorological Instruments and Methods of Observation (CIMO Guide) : • The 1st edition published in 1954, 12 chapters. • The 7th edition (2008) has 34 chapters, • covering the whole range of instruments, • from the simplest to the most complex and sophisticated. • Its purpose is to give comprehensive and up-to-date guidance on the most effective practices for carrying out meteorological observations and measurements
