DRAKKAR data DRAKKAR is an upward pointing, two channel microwave radiometer. Its channels are 23.8 and 36.5 GHz, and the antenna aperture is about 15deg. It has been developed at CRPE on the base of the ATSR/M (ERS-1/MWR) design. Its basic sampling was 0.5s during ASTEX. The calibration was performed before the campaign, verified using a cold load on 12 June, and verified again after return to France. During ASTEX, DRAKKAR was located on the upper level, upward pointing. The file `xx_06_92.DAT' corresponds to the day xx of JUNE 1992. Each article is respectively composed by: * the hour of the beginning of the 30s seconds period on which averages are done. * the 6 following numbers are the mean and the standard deviation of the microwave brightness temperatures - 23.8 GHz and 36.5 GHz-, and of the integrated water vapor content (in g/cm2). Empirical corrections have been done for the first june to the seventh (calibration variation due to the change of the "radome" sheet). Data processed at CRPE by E. Gerard and L. Eymard
