25 1001 Loewenstein, M., Jost, H., Sharer, P., Grose, J., Jensen, S., Mai, N., Marmie, J. NASA-Ames Methane (Argus) OMS/STRAT 1 1 1997 02 14 1997 04 11 0 Elapsed time in UT seconds from 0 hours on the given flight date 1 1.0 9999.999 Methane Mixing Ratio (ppb) 6 This is a prliminary data set for this flight. A refined analysis algorithm has been developed to analyze the data. Some missing data is due to remaining problems with the Argus instrument that cause data dropouts in some portions fo the flight. While both the data and the analysis appear secure, it is too early to assign error estimates. 4 ****** Preliminary Data ****** Data from the Dual Channel Laser Spectrometer, Argus, flown aboard the OMS in situ gondola from Juazeiro do Norte, Brazil 7.2 S, 39.3 W.
