Application of Airborne Passive Microwave Measurements for INDOEX

该项目支持将在1999年2月至3月期间进行的印度洋实验。INDOEX的主要目标是测量气溶胶对对流层辐射能量收支的直接和间接影响。为了支持INDOEX，我们建议在NCAR C-130研究飞机飞行INDOEX期间部署先进的微波成像辐射计(AIMR)。我们计划分析AIMR的数据，以确定在辐射计的带状区域上确定的云液态水路径(垂直积分的云液态水的量)。该数据集还可用于确定降雨率和估计综合水汽路径(可降水量)。该项目通过提供有关低层云的液态水路径中的梯度的信息来支持INDOEX的主要科学目标，以帮助解释气溶胶对辐射通量的间接影响。

This project supports the Indian Ocean Experiment (INDOEX) to be conducted during the period February-March 1999. The principal goal of INDOEX is to measure the direct and indirect effects of aerosol on the tropospheric radiative energy budget. To support INDOEX, we propose to deploy the Advanced Microwave Imaging Radiometer (AIMR) on the NCAR C-130 research aircraft during its flights for INDOEX. We plan to analyze the AIMR data for cloud liquid water path (vertically integrated amount of cloud liquid water) determined over the swath of the radiometer. This dataset can also be used to determine rainfall rate and to estimate integrated water vapor path (precipitable water). This project supports INDOEX primary scientific objectives by providing information on gradients in the liquid water path of low-level clouds, to aid in the interpretation of the indirect effect of aerosols on the radiative fluxes.
