The following daily average vertical column abundances were retrieved from solar absorption spectra measured by the Bruker Interferometer, a FTIR spectrometer, in Bremen. The retrieval of the column abundances was performed by the GFIT algorithm, which used temperature profiles from sondes launched daily in Ny-Aalesund, and an initial set of vmr profiles derived from MkIV balloon measurements (G. Toon, JPL), which were then stretched/compressed to account for day-to-day variations in the tropopause altitude and subsidence. The errors tabulated in the main part of the data file, determined from the quality of the spectral fits, represent the 1-sigma measurement precisions. These errors are appropriate for comparing columns measured on different days. For most gases, the main systematic errors arise from uncertainties in the assumed vmr profiles shapes, and from uncertainties in the spectroscopic parameters (of both the target gas and interfering gases). PRIMARY VARIABLES. All primary variables are vertical column abundances in molec.cm-2 AUXILIARY VARIABLES. year Mean time of observation (fractional years) day Mean time of observation (fractional day of the year) hour Mean time of observation (fractional UT hour of the day) run extension of spectrum file name (for internal use only) lat Latitude (degrees, N +ve) of observing instrument long Longitude (degrees, E +ve) of observing instrument zobs Geometric Altitude (km) of observing instrument pobs Outside pressure (mbar) at observing instrument tobs Outside temperature (C) at observing instrument asza Astronomical Solar Zenith Angle (deg.) at observing instrument zmin Lowest press. altitude (km) encountered along path of chief ray graw Spectral point spacing (cm-1) of spectrum opd Optical Path Difference (cm) of interferogram fovi Internal Field Of View (rad) of radiation inside FTIR. Note that "day" and "hour" are completely redundant since day = 365.25*(year-int(year)) ; hour = 24.000*(day-int(day)) They are nevertheless included for the convenience of the user. Note that hour is allowed to exceed 24.0 in order to avoid introducing an apparent time discontinuity between observations made at 3:59 pm local time and 4:01 pm local time on the same day (Pacific Time is 8 hours behind UT). The true UT hour can be obtained simply by amod(hour,24.). Although in theory ZOBS (the geometric altitude) and ZMIN (the altitude at which the model pressure equals POBS) should be identical for solar zenith angles less than 90 degrees, in practice they differ by up to 100m due to uncertainties in the observation pressure (POBS) and the T/P model. --------------------------------------------------------------------------- 1 2008.33705612 123.36254
