Abstract

Passive microwave radiometry from satellites provides more precise atmospheric temperature information than that obtained from the relatively sparse distribution of thermometers over the earth's surface. Accurate global atmospheric temperature estimates are needed for detection of possible greenhouse warming, evaluation of computer models of climate change, and for understanding important factors in the climate system. Analysis of the first 10 years (1979 to 1988) of satellite measurements of lower atmospheric temperature changes reveals a monthly precision of 0.01 degrees C, large temperature variability on time scales from weeks to several years, but no obvious trend for the 10-year period. The warmest years, in descending order, were 1987, 1988, 1983, and 1980. The years 1984, 1985, and 1986 were the coolest.

摘要

卫星被动微波辐射测量比从地球表面相对稀疏的温度计分布中获得的大气温度信息更精确。为了检测可能的温室效应变暖，评估气候变化的计算机模型，以及了解气候系统中的重要因素，需要准确的全球大气温度估计。对卫星测量的低层大气温度变化的前 10 年（1979 年至 1988 年）的分析表明，每月的精度为 0.01 摄氏度，在从数周到数年的时间尺度上存在较大的温度变化，但在 10 年期间没有明显的趋势。最温暖的年份依次为 1987 年、1988 年、1983 年和 1980 年。1984 年、1985 年和 1986 年是最冷的年份。
