Temperature soundings from rocketstondes used by the USSR have been compared to temperature retrievals obtained in low, middle, and high latitudes by the LIMS instrument on Nimbus 7. The rocket and satellite temperatures agree at low altitudes, but the rocket temperatures are about 10 K cooler near the stratopause. There is a tendency for the agreement to become better in the mesosphere, but there appear to be significant differences between day and night comparisons. A day-night correction curve is derived, and the USSR comparisons are converted to day conditions. A comparison between LIMS and U. S. rocketsondes in the same latitude bands shows generally good agreement up to the stratopause, but above that the U. S. rocket temperatures are warmer. Then, using the LIMS as a transfer standard, rocketsondes from the United States and the Soviet Union are intercompared. The differences are similar in all three latitude bands but larger than those found in the previous (1977) intercomparison. The differences determined in this study should be more representative, since they represent a variety of locations and seasons as well as standard operational procedures. |
