GENEVA (AP) -- The hole in the earth's ozone layer is growing faster than ever and is already twice the size it was this time last year, the U.N. weather agency said Tuesday. Ozone, a gas in the stratosphere, prevents harmful ultraviolet radiation from reaching the earth. Its depletion, caused in large part by industrial chemicals, is believed to increase the incidence of skin cancer and cataracts. The hole, first observed over Antarctica in the 1980s, has reappeared each September and October since then. With the onset of winter in the polar region, temperatures plung in the stratosphere and hasten ozone depletion. The hole is getting bigger despite a reduction in ozone-destroying chemicals such s chlorine and bromine because these chemicals have a life of 60 to 100 years. So far the hole has expanded to 3.9 million square miles -- roughly the size of Europe -- according to the World Meteorological Organization. At that rate, the hole could surpass the record 24 million square

VLF Radio Receiver Development Bibiography     A. INTRODUCTION   The ultra-low-power radio receiver will measure extremely low frequency (ELF, 30 Hz to 3 kHz) and very low frequency (VLF, 3 kHz to 30 kHz) electromagnetic waves in polar regions. The receiver will be compact and low cost enough to allow for deployment of multiple units in a ELF/VLF interferometer configuration (e.g., see Figure 6), to determine the spatial location, shape and extent of ionospheric exit regions illuminated (from above) by plasma waves of magnetospheric origin. It would provide substantial advances in o
