TCSP HIGH ALTITUDE MMIC SOUNDING RADIOMETER (HAMSR) V1

The High Altitude MMIC Sounding Radiometer (HAMSR) is a 25-channel microwave atmospheric sounder operating as a cross-track scanner. There are three bands: an 8-channel band near 50-GHz, used for primary temperature sounding; a 10-channel band near 118 GHz, used for secondary temperature sounding and assessment of scattering; a 7-channel band near 183 GHz, used for water vapor sounding. The instrument is continuously self-calibrating using internal calibration targets. Radiometric sensitivity at the composite sampling cells provided in the archive is typically 0.1 and ranges up to 0.25 K for the stratospheric channels. Calibration accuracy is estimated at better than 1 K for temperature sounding and better than 2 K for water vapor sounding. Temperature weighting function peaks are distributed between the surface and the flight altitude. HAMSR was mounted in a wing pod of a NASA ER-2 research aircraft. The TCSP mission collected data for research and documentation of cyclogenesis, the interaction of temperature, humidity, precipitation, wind and air pressure that creates ideal birthing conditions for tropical storms, hurricanes and related phenomena. The goal of this mission was to help us better understand how hurricanes and other tropical storms are formed and intensify. Regular image processing was available beginning on 12 July. The scan schedule was maintained through the end of July.

高海拔毫米波辐射计（High Altitude MMIC Sounding Radiometer，简称 HAMSR）是一种25通道微波大气探测仪，以横切扫描方式工作。该设备包含三个频段：一个位于50-GHz附近的8通道频段，用于主要温度探测；一个位于118 GHz附近的10通道频段，用于次级温度探测及散射评估；一个位于183 GHz附近的7通道频段，用于水汽探测。该仪器通过内部校准目标进行连续自校准。在存档提供的复合采样单元中，辐射计量灵敏度通常为0.1，对于平流层通道，其范围可达0.25 K。校准精度估计在温度探测方面优于1 K，在水汽探测方面优于2 K。温度权重函数的峰值分布在地面与飞行高度之间。HAMSR被安装在美国国家航空航天局ER-2研究飞机的翼盒内。TCSP任务旨在收集数据，以研究并记录气旋生成过程，即温度、湿度、降水、风速和气压相互作用，为热带风暴、飓风及其相关现象的理想孕育条件。此次任务的目标是帮助我们更好地理解飓风及其他热带风暴的形成与增强过程。从7月12日起，常规图像处理成为可用。扫描计划一直维持至7月底。
