Increasingly, technology development has enabled higher spatial temporal and spectral resolution observations from space and this has resulted in more accurate and higher spatial and temporal resolution inferred geophysical parameters. Here we discuss the benefit of these high resolution observations in areas such as current and future hyperspectral infrared sounding, microwave sounding, radio occultation sounding and high resolution wind estimation from space. We show the considerable benefit from the high resolution observations supporting these activities and the potential to improve current capability by both extended use of the current observational capacity and by use of future high resolution observation platforms. For example in the case of hyperspectral infrared sounding the benefits of using increased channel numbers, cloudy radiance data and accurate estimates of the emissivity will be shown (Noting for instance the accurate estimate of emissivity requires an increased availability of surface viewing channels). In the case of microwave sounding, radio occultation sounding and high resolution wind estimation again the link between high resolution observations and high quality forecasts has been established. Examples of these will also be provided.
In summary EOS form a vital part of NWP and climate monitoring. The benefits now being demonstrated by the improving spatial spectral and temporal resolution observations available from current and future space-based platforms indicate considerable potential for providing significant increase in social and economic benefits to the community.
