<br />8 <br /> <br />V, Ill:" and U700 were determined for eaGh period when simultaneous <br />rawinsonde and radiometer data were available. Th~ individual values of <br /> <br />these variables for each rawinsonde launch are summarizeq in Table II. <br /> <br />,. <br /> <br />The data were also compiled for each STORM and ~re summqrized in Table <br /> <br />III. <br /> <br />Rawinsonde and radioDleter data were available for different parts <br /> <br />of eaoh decl~red .storm period. Nearly all data loss occurred during <br /> <br />storms 1-4 when the radiometer was not operating.
