GRIP HIGH-ALTITUDE MMIC SOUNDING RADIOMETER (HAMSR) V1

The GRIP High-Altitude MMIC Sounding Radiometer (HAMSR) dataset was collectd by the High Altitude monolithic microwave integrated Circuit (MMIC) Sounding Radiometer (HAMSR) is a microwave atmospheric sounder developed by JPL under the NASA Instrument Incubator Program. The new HAMSR with 183GHz LNA receiver reduces noise to less than a 0.1K level improving observations of small-scale water vapor. HAMSR has 25 spectral channels which are split into 3 bands: an 8-channel band centered 53-GHz, used to infer the 3-D distribution of temperature; a 10-channel band centered at 118 GHz, used for secondary temperature sounding and assessment of scattering; and a 7-channel band centered at 183 GHz, used to measure water vapor (humidity) and cloud liquid water content in the atmosphere. The major goal was to better understand how tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft and the Global Hawk Unmanned Airborne System (UAS), configured with a suite of in situ and remote sensing instruments that were used to observe and characterize the life cycle of hurricanes.

GRIP高海拔单片微波集成电路（MMIC）探测辐射计（HAMSR）数据集由NASA仪器孵化器计划下的喷气推进实验室（JPL）开发。新型HAMSR配备了183GHz低噪声放大器（LNA）接收器，将噪声降低至0.1K以下，从而提高了对小尺度水蒸气的观测。HAMSR拥有25个光谱通道，分为三个波段：一个以53GHz为中心的8通道波段，用于推断温度的三维分布；一个以118GHz为中心的10通道波段，用于辅助温度探测和散射评估；以及一个以183GHz为中心的7通道波段，用于测量大气中的水蒸气（湿度）和云中液态水含量。其主要目标在于更深入地理解热带风暴如何形成并发展成大型飓风。NASA利用DC-8飞机、WB-57飞机以及全球鹰无人机系统（UAS），配备了一套原位和遥感仪器，用于观测和描述飓风的生命周期。
