Abstract: Provided are techniques for numerically integrating an intensity distribution function over a numerical aperture in a manner dependent on a determination of whether the numerical aperture spans a Rayleigh singularity. Where a singularity exists, Gaussian quadrature (cubature) is performed using a set of weights and points (nodes) that account for the effect of the Wood anomaly present within the aperture space. The numerical aperture may be divided into subregions separated by curves where the Wood anomaly condition is satisfied. Each subregion is then numerically integrated and a weighted sum of the subregion contributions is the estimate of the integral. Alternatively, generalized Gaussian quadrature (cubature) is performed where an analytical polynomial function which accounts for the effect of the Wood anomaly present within the aperture space is integrated. Points and nodes generated from a fit of the analytical polynomial function are then used for integration of the intensity distribution function.

Abstract: Liquid precipitation and snow precipitation measurements having a first resolution and spanning a first time period are aggregated with data from a computer generated model of current liquid precipitation and snowfall estimates having a second resolution and spanning a second time period to form near up-to-date estimates of liquid precipitation and snowfall over a determined time period. The measurements are received from various weather history data severs over a network. The data is processed into a gridded data set for a determined geographical region. The current conditions estimates are received over a network from a different sever. The processor then aggregates the processed liquid and snow precipitation estimates with the current precipitation estimates corresponding to the period from the most recent precipitation and snowfall data until present.
