. Future plans The current DFRm method does not use the dual-frequency data fully. It is expected that the dual-frequency data give us useful information about the phase of particles in the upper part of storm (e.g., Liao and Meneghini 2011 ). If we develop a method to analyze the DFRm in the upper part of storm extensively, then we may be able to use that information, for example, for the type classification of the almost snow-only case in the mid- and high latitudes in winter. Other future plans

Pole, and global AVHRR wind product coverage—(bottom left) on MSG disk area and (bottom right) over North Pole. Table 1. AVHRR wind products extracted at EUMETSAT. 2. Description of the algorithm The MetOp satellites are part of the EUMETSAT fleet of meteorological satellites, providing weather and climate data. The EPS program consists of a series of three polar-orbiting MetOp satellites that are planned for more than 14 years of operation ( Klaes et al. 2007 ). The satellites MetOp-A (launched

the Ka-band single- and dual-frequency estimates, studies using measured raindrop size distributions show that p is not constant but depends on the parameters of the size distribution. Whether improvements in the determination of p can be made with the measurements available is an open question. Several refinements and upgrades to the algorithm are planned. The most important is implementation of the temporal reference. Although this will begin with a 0.5° grid resolution, an example of which
