Abstract
The Rayleigh Temperature and Density Lidar (RDTL) at Poker Flat Research Range (PFRR) characterizes gravity wave activity in the middle atmosphere through measurement of atmospheric density fluctuations. To date the measurements have been used to analyze wave activity in the 40-50 km altitude range using the noise variance subtraction method. We apply the recently developed interleaved method to the existing RDTL data acquisition process and present the results. We compare the results obtained from the interleaved method with the previously used noise variance subtraction method. The method shows significant differences in the estimates of the gravity wave activity at higher altitudes.
