【摘要】 将乌鲁木齐探空站400 MHz电子探空数据与MP-3000A型地基微波辐射计探测数据进行比较,主要分析了距地高度在0～10 000 m的58个高度层的温度、相对湿度误差情况,分析了误差产生的原因,简单介绍了地基微波辐射计物理量垂直廓线图的实际应用情况,认为MP-3000A型地基微波辐射计提供的物理量垂直廓线图在监测和分析天气系统方面有一定的优势;地基微波辐射计的探测准确性远低于传统气球探空,准确性不高是目前的主要问题;地基微波辐射计还需要在实践中不断改进和完善;气象技术人员还需要不断积累地基微波辐射计的应用经验和技巧;地基微波辐射计在气象领域的前景较好。更多还原

【Abstract】 We compared the 400MHz electronic sounding data from Urumqi sounding station with the explored data from MP-3000A ground-based microwave radiometer,analyzed the error of temperature,relative humidity at 58 height layer within 0-10000 meters high from the ground,discussed the causes of errors and introduced briefly the actual application status for the vertical profile chart of physical quantities from MP-3000A ground-based microwave radiometer.The vertical profile charts offered by MP-3000A have certain advantages in monitoring and analysis of weather systems.The exploration accuracy of MP-3000A is much lower than that of conventional balloon sounding,and the low accuracy is the main problem for MP-3000A.The ground-based microwave radiometer needs to be improved constantly in practice operation,and meteorological technicians also need to accumulate the experience and technique for the application of ground-based microwave radiometer.MP-3000A ground-based microwave radiometer has a promisingfuture in the field of meteorology.更多还原
