This dataset contains netCDF data files that hold selected variables from the NCAR Gulfstream V (GV) aircraft, instrument observations, and large-scale meteorological variables interpolated in space and time from the high-resolution NCEP Global Forecast System (GFS) 6-hourly global analyses. Variables are given at 1-second time resolution for the duration of the flight.
The files also include a number of derived variables, such as equivalent latitude, potential temperature lapse rate (stability), temperature at the tropopause, etc. The equivalent latitude suffers from ambiguities when the isentropic surface of interest intersects the ground. Therefore, the eqlat_GFS variable has attributes listing the theta surfaces on which it was computed and the amount of missing data on each surface. This can be used as a measure of the reliability of the equivalent latitude.
Merging of the instrument data is completed directly for instruments with 1-second sample times. For instruments with longer sample times, the data are merged at the central time of the sample window.
See the README files for the instrument and GFS data files for further details of the included parameters. An ncdump of a sample merged file is given below.
