A device that automatically and continuously records the water equivalent of snow on a given surface as a function of time. A small sample of a radioactive salt is placed in the ground in a lead-shiel
ded collimator that directs a beam of radioactive particles vertically upward. A Geiger-M ller counting system (located above the snow level) measures the amount of depletion of radiation caused by the presence of the snow.
Emissions of the sun in radio wavelengthsfrom centimeters to dekameters, under both quiet and disturbed conditions.Radio Bursts can be "Type I" consisting of many short, narrow-band bursts inthe metri
c range (300 - 50 MHz).; "Type II" consisting of narrow-bandemission that begins in the meter range (300 MHz) and sweeps slowly (tens ofminutes) toward dekameter wavelengths (10 MHz).; "Type III" consisting ofnarrow-band bursts that sweep rapidly (seconds) from decimeter to dekameterwavelengths (500 - 0.5 MHz); and "Type IV" consisting of a smooth continuumof broad-band bursts primarily in the meter range (300 - 30 MHz).
