Positive means a positive test charge would drift to the right of the direction of the aircraft under the influence of the field. Positive means a positive test charge would drift upward under the influence of the field. The direction of motion relative to the ground with respect to true north, derived from the GPS ground track angle with respect to magnetic north. 290 X-acceleration Acceleration in the direction of aircraft motion. Acceleration toward the left yields a positive value.
Upward acceleration produces a positive value.
341 Calculated FSSP Total Count Observed FSSP total counts with minor corrections made in an attempt to correct for the effects of ice particles on FSSP droplet spectra. Not fully proven. Calculated FSSP Average Diameter FSSP average droplet diameter estimated from spectra calculated using the Baumgardner FSSP data reduction procedure. 344 Calculated FSSP Water Liquid water concentration estimated using the Baumgardner FSSP data reduction procedure. 348 Calculated FSSP Equivalent Diameter Computed as for tag 144, but using FSSP spectra derived using the Baumgardner FSSP data reduction procedure.
