The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...

A global three-dimensional (i.e. latitude, longitude, altitude) climatology of tropospheric ozone is derived from the ozone sounding record by trajectory mapping. Approximately 52 000 ozonesonde profiles from more than 100 stations worldwide since 1965 are used. The small number of stations results in a sparse geographical distribution. Here, forward and backward trajectory calculations are per...

[1] We validate the temperature climatology recorded by the Microwave Sounding Unit with GPS occultation data collected by the GPS/MET experiment. We choose to validate only the lower stratospheric MSU climatology in order to circumvent the wet-dry ambiguity associated with GPS occultation in the midto lower troposphere. We simulate the lower stratospheric channel’s brightness temperature by co...

Recently there has been increased interest within the U.S. Navy in the use of climatology-based products to support the planning and execution of military operations. Climatological databases of atmospheric features that impact electromagnetic (EM) propagation have been developed to provide guidance on weapons and sensor system performance for expected environmental conditions. However, the mar...

We expect a numerical simulation to improve upon our first guess; typically some sort of climatology. If a model is not better than this initial estimate of the ocean state, the model provides no new information and serves no purpose. Very often in coastal regions we are interested in predicting events—episodes when the ocean state differs greatly from the climatology. The ability of a model to...
