A field program was carried out at Wallops Island, Virginia in which a number of in situ soundings were made during February to May 1980 in conjunction with near overpasses of NOAA-6. A comparison of NOAA-6 measured and derived quantities with those of in situ instruments was made. Positive temperature biases (satellite warmer) were found to appear in the lower troposphere and tropopause regions; negative differences generally were found to appear in the middle and upper stratosphere. Average geopotential height differences were relatively small at all levels, but increasing rms errors showed decreasing reliability with height of satellite geopotential heights. Satellite-derived geostrophic winds were found to have less shear than in situ determined winds. Bias in the directional differences was found to range from less than 5 deg to about 20 deg, with rms differences apparently decreasing near the level of wind speed.
