Abstract: A possible method for assimilating large quantities of asynoptic data, such as satellite observations, into numerical weather forecasts, is investigated. The method is based on a transformation of the time coordinate to ...

Abstract: A study is made of the geophysical algorithms relating the Seasat-A scatterometer (SASS) backscatter measurements σ° with a wind parameter. It is shown that although σ° is closely related to surface features, identification ...

Abstract: An investigation of three finite-difference methods and their response to the insertion of simulated satellite data is presented. A simple one-level barotropic model is used as the ?forecast? model, while the Mintz-Arakawa ...

Abstract: Objective analysis can he performed on irregularly spaced observation points by fitting selected functions to the observations. A simple least-squares fit is found to be both impractical and ill-conditioned, the latter ...

Abstract: During March, 1978 on a snow-covered field near Lee Vining, California, measurements were made that included: 1) variations above the snow surface of the net radiative flux and the profile of wind speed, air temperature ...
